| Introduction | | | | With the debut of the exciting new SH300i, Honda proudly presents the sleek and dynamic new standard of mid-displacement scooters for years to come. A direct DNA descendant of Europe’s best-selling scooter, the SH150i/SH125i, the gracefully attractive new SH300i inherits its predecessor’s design concept of ‘light, compact and best balanced.’ It also inherits the original SH’s distinctive large-diameter 16" wheels, wide, flat step-through floorboard, sleek design and comfortable riding proportions that have made the SH150i such a remarkable hit on the urban streets of Europe. The new, larger-displacement SH also features a totally new fuel-injected four-valve, four-stroke engine that delivers the strongest acceleration in its class, and a rigid new chassis design with an innovative floating link system that ensures peerless handling on both crowded city streets and open suburban highways.
Honda’s engineers saw a glaring need for a perfect model to bridge the gap between the slim size and effortless riding ease of the popular SH150i/SH125i and the stronger performance of the bigger and bulkier models found in the scooter market’s larger-displacement classes. They thus boldly set out to create an entirely new scooter concept that could provide the exhilarating power, acceleration and handling of a larger-displacement scooter or motorcycle while maintaining the more manageable size and proportions—and effortless convenience—that have made the SH150i/SH125i one of the most popular scooters on the streets of Europe.
With an eye toward expanding the versatile appeal of scooters beyond the dense traffic of city centres to more open suburban roads and highways, Honda’s engineers designed the new SH300i from the ground up to provide an exhilarating yet totally satisfying blend of performance, comfort and convenience that will surely establish it as the strongest and most versatile mid-distance city commuter on the roads of Europe.
Slender and compact for the ultimate in riding ease, yet quick, powerful, and sure-handling to cover longer distances with quietly assured confidence, the new SH300i is also fully equipped with ample carrying capacity and convenience features. Optionally available with the superior stopping control of Honda’s most advanced Combined Antilock Brake System, and sleekly styled with a cosmopolitan sophistication and attention to quality and detail that will surely make it one of the most widely popular commuters for these times, with the debut of the all-new SH300i, the new Standard of mid-displacement scooters has finally arrived. |
| | | back to top | | | | Development Concept | | | | Starting from the chosen goal of creating Europe’s ‘Best Commuting Partner,’ Honda’s scooter development team set out to expand on the established attractions of the popular SH150i/SH125i with the added benefits of stronger performance and confident high-speed handling ease. Four points of focus were determined from the start:
• Light weight and compact proportions for brisk, light-handling manoeuvrability
• Easy and convenient operation
• High quality and comfort in both look and function
Desired features included:
1) A more powerful engine with the fastest acceleration and smoothest operation in its displacement class. However, without the size and weight common to other scooter engines in this class.
2) A slim and lightweight configuration with the shortest wheelbase in its class, for easier manoeuvrability and sharper cornering control.
3) The large-diameter 16" wheels made popular with the SH series, which provide smoother and more comfortable handling, especially at the higher speeds that this new mid-displacement scooter would be capable of reaching.
4) The spacious flat floorboard area also strongly associated with the SH concept, which permits easy mounting and dismounting, and greater foot and leg positioning freedom, unlike the large central frame tunnel designs found on many models in the class.
5) Ample and secure carrying capacity.
6) Large-diameter hydraulic disc brakes with ABS also available in an additional version.
7) Low noise and vibration to complement its stronger high-speed performance.
8) Low fuel consumption and ultra-low exhaust emissions to reflect the world’s ever-growing concern for the environment and comply with the latest, most strict EURO-3 emissions regulations.
However, accomplishing these and other related goals proved to be much easier to conceive of than to actually carry out. An entirely new engine had to be designed and developed that could deliver the desired top performance from an unprecedented compact form. A new approach to frame construction also had to be thought out in order to ensure the highest degree of rigidity for top riding performance and handling ease while still preserving the main features that make the SH series so popular, such as its slim proportions and flat floorboard.
Simply maintaining the SH’s characteristic spacious flat floorboard—the only one of its kind in the entire mid-displacement scooter class—proved to be a major challenge, and unique design innovations were developed to ensure that the frame could capably withstand the extra power and torsional forces that would be exerted on a higher-displacement version of the SH at motorway speeds.
Exceptional comfort and control were also priorities in this new scooter’s design, and impressive design innovations in the form of a unique floating link unit swingarm make possible one of the smoothest, quietest, and most comfortable rides to be found in any class of scooter, yet remarkably coupled with the swift, responsive high-speed handling that can make longer commutes a more pleasant experience, and only thought possible on a true motorcycle till now.
In keeping with its stated design goal of becoming ‘Europe’s Best Commuting Partner,’ the new SH300i was also designed from the start to be equipped with Honda’s most advanced Combined antilock brake system (Combined ABS), for effortless stopping control on par with the new model’s exceptional performance and handling, and a unique feature in its class.
Slim, compact and sleekly attractive styling; breathtaking engine performance and acceleration; precise and confident handing on both city streets and high-speed motorways; luxurious comfort, modern convenience and impeccable attention to detail. Never before thought possible, and only made possible by the world’s number one motorcycle manufacturer. Not just another scooter, it’s time for the world to make room for the all-new Honda SH300i. The next generation of two-wheeled transportation has finally arrived. |
| | | back to top | | | | Styling | | | | The all-new SH300i features a ‘Solid and Elegant’ design image of sleek lines and slim proportions that exude the highest sense of quality and prestige. Borrowing many of its distinctive design fundamentals from the phenomenally popular SH150i/SH125i big-wheeled scooter that has taken Europe by storm since its 2001 debut, the new SH300i carries the slim and lively SH concept to a larger class and a new generation of riding and commuting pleasure.
Slim & Compact Configuration
Specially designed to be slimmer and easier to handle than the vast majority of scooters in the mid-displacement class, the SH300i’s overall length is only 3% longer than that of its smaller-displacement predecessor, the SH150i/SH125i. One of the lightest, narrowest and most compact models in its class, the SH300i establishes a new direction in scooter design and function, providing exceptionally comfortable riding ease combined with its impressively strong power delivery and crisper, more sporty handling.
Like its predecessor, the SH300i’s most distinctive design features include:
a) Slim proportions, especially compared to other scooters in its displacement class,
b) Spacious flat floorboard area for easy mounting and dismounting and enhanced leg and foot manoeuvring ease while on the move and
c) Big, motorcycle-like 16-inch (40.6cm) diameter wheels mounted with wide, low-profile tyres, which provide a smooth and confidently assured ride that compares more favourably to a real motorcycle than do the much smaller wheels found on many other scooters.
d) Easy-mounting 785mm seat height, which provides an ideal balance of optimal rider eye level and comfortable seating with a relatively easy reach to the ground thanks to its narrow proportions.
Attention-Getting Lighting
The SH300’s fuller, more elegantly curvaceous scooter styling comfortably surrounds the rider, and is highlighted in front by a large clear-lens multi-reflector headlight designed to provide maximum illumination over a wide area for excellent night-time visibility. The sleek front bodywork also incorporates distinctive clear-face front indicators with amber bulbs into its smooth design, which also feature ever-on position lamps positioned behind clear plastic lenses which work together with the headlight to enhance visibility and ease other motorists’ judgement of the vehicle’s distance and approaching speed. At the rear, a fully integrated tail-light and rear indicator assembly. |
| | | back to top | | | | Colouring Concept | | | | The new SH300i will be released in five luxurious colour variations that beautifully accentuate its inherent feel of quality and prestige. Leading off is a regal metallic red that exudes a luxurious and lively image to complement its slim lines, light weight and responsive performance. Next, a crisp, brightly reflective metallic silver gives expression to the SH’s technological sophistication. In deep pearlescent blue, the new SH sets the tone of success for business district commuters with people to see and schedules to keep. A bottomless pearlescent black shimmers in the bright lights to project an urbane sense of quality and sophistication in keeping with the new leader of the mid-displacement scooter class. Last, a glistening light pearlescent green exudes the comfort and confidence of an experienced traveller that is just as happy in the city’s hustle and bustle as it is speeding down the highway.

| | | back to top | | | | Engine | | | | The new SH300i is powered by an all-new liquid-cooled, fuel-injected engine which produces the highest performance and strongest acceleration in its class. Not merely a larger displacement version of an existing design, the SH300i’s advanced power unit was uniquely developed and crafted to meet its specific needs, and packed with design features and technologies developed in the racing world and then adapted to this next-generation scooter.
Advanced Honda Racing Technology
For the Smallest Engine in the 250cc Scooter Class
The SH300i’s newly developed 279cm3 SOHC 4-valve engine borrows much of its highly advanced technology from Honda’s famous CRF series of motorcross racers, which are powered by some of the most compact, lightweight and highly competitive engines in their respective classes. In particular, its innovative sealed crankcase configuration, directly influenced by Honda’s high-performance CRF engine design, makes possible much smaller and more compact dimensions than any single-cylinder scooter engine in its class. Besides being the most compact scooter engine ever developed in its displacement class, the SH300i’s new sealed crankcase engine design also maximises power output by minimising internal resistance losses.
Internal Resistance Minimised For Stronger Power
Unlike most wet sump engines, the SH’s crankshaft never comes into direct contact with the engine’s reservoir of oil. This eliminates the occurrence of power-robbing windage, which results from the crankshaft contacting the upper surface of the oil sump and churning it into a dense foam. Instead, the SH300i’s engine oil is held inside a separate chamber within the engine, and lubricating oil circulating within the crank cavity is quickly evacuated through a one-way reed valve leading back to the oil reservoir cavity with each rotation of the crankshaft. This elimination of oil windage results in significant improvements in power production, quicker acceleration and a major contribution to the SH300i’s excellent fuel economy.
The engine’s sealed crankcase design also allows the oil reservoir to be positioned for the most compact dimensions, and even allows its oil pan to be raised for ample ground clearance while lowering the engine’s centre of gravity.
Reduced Crankcase Air Pressure
The SH300i’s new engine was also designed to minimise power losses associated with air pressure build-up within its compact crank cavity. As an engine’s piston falls on the intake and power-producing combustion strokes, the air inside the lower crankcase compresses, causing air pressure resistance or pumping loss that can act as a damper and drag on power output. Instead of using a crankcase relieve valve to vent excessive air pressure to the atmosphere, the SH300i’s engine utilises the same large one-way reed valve to quickly evacuate both internal oil and building air pressure to the lower reservoir chamber, thus further minimising this source of power-robbing internal resistance.
Plain Bearing Crankshaft
Making another contribution to both reduced frictional loss and smoother operation are plain crankshaft journal bearings replacing the roller bearings normally found in this class of scooter engine. Plain bearings ensure not only smoother, but quieter operation, and further optimise the SH300i’s power characteristics.
Benefits of Reduced Internal Resistance
The end results of these efforts to minimise internal friction and resistance can be immediately seen in the SH300i’s sharper and stronger low-to-midrange acceleration, which combines with its slim, lightweight form to provide surprisingly strong take-offs and impressive performance from such a ‘small’ scooter. In fact, the SH300i’s low-to-midrange acceleration is easily the strongest and fastest in its entire class, and its top-end performance is also well-suited to long cruises on the motorway. No more sluggish acceleration, the SH300i delivers the performance one might expect of a motorcycle with the comfort, ease and elegance of an ideal commuting partner.
Another important benefit is the SH300i’s vastly improved fuel economy, with measured consumption figures of 28 kilometres per litre averaging nearly three kilometres more than most comparable 250cc single-cylinder scooter engines, even with its larger displacement and full EURO-3 emissions compliance taken into consideration.
PGM-FI Electronic Fuel Injection System
The new SH300i’s advanced engine is also equipped with Honda’s most advanced scooter-oriented programmed fuel injection system for remarkably smooth and efficient operation combined with a strong, responsive power delivery. Miniaturised and fully integrated into its 34mm bore throttle body are the system’s electronic control unit (ECU), air temperature and pressure sensors, and even its high-performance digital ignition. This compact system not only ensures dependable starting and strong performance in all riding conditions, it also makes a big contribution to the SH300i’s miserly fuel economy. Its average fuel consumption of approximately 28 kilometres per litre of fuel adds up to a remarkable range of over 250 kilometres on a single tank full of petrol. In these days of rising fuel costs, a fast, friendly and economical commuter like the SH300i really stands out.
Ultra-Low Emissions Meet EURO-3 Regulations
The SH300i’s advanced PGM-FI fuel injection system not only assures optimal performance in virtually all riding conditions, it also plays a central role in maintaining the engine’s remarkably high fuel efficiency and low exhaust emissions. Its HECS3 oxygen-sensing clean emissions system also features a high-efficiency 300-cell catalyser element built into the exhaust system to neutralise harmful exhaust gas emissions and ensure easy compliance with strict EURO-3 exhaust emissions regulations currently in effect.
Stepless V-Matic Transmission
Like most of Honda’s latest scooters, the SH300i gets its power to the ground via a rugged V-Matic belt-converter transmission which provides strong, smooth acceleration at the turn of its throttle. A high-accuracy torque sensor complements the transmission’s wide ratio to take maximum advantage of the engine’s strong low-to-midrange torque output and provide strong surges of acceleration—even when carrying a passenger—combined with smooth, linear engine performance and reliable long-term operation. |
| | | back to top | | | | Chassis | | | | Designed from the ground up to not only provide commuters with a comfortable urban ride, but also superb handling and confident control at faster highway speeds while adhering to its main development concept of achieving a ‘Simple and Slim Design,’ the new SH300i is built on a specially engineered frame with a uniquely designed floating link unit swingarm. Its specially designed chassis also features the shortest wheelbase in the mid-displacement scooter class for exceptionally light handling and easy manoeuvrability in tight traffic situations.
High-Rigidity Step-Through Frame
The SH300i’s big-wheel scooter configuration also features a comfortably low, wide and flat floorboard area that is unique to its displacement class and has become a hallmark of the popular Honda SH series of scooters. In order to ensure that this design also provides the high degree of rigidity required for both its more powerful 280cc engine and precise, responsive handling at highway speeds, the frame is constructed of large-diameter steel tubing in a reinforced design.
Roughly based on the popular SH150i/SH125i’s similar flat floorboard underbone frame design, the new SH300i’s frame further features an added inverted ‘Y’ segment, which reaches down from the top of the steering to the two lower rails at the front base of the floorboard area. Meeting up with the frame’s two main down-tube sections as they curve backward along the lower rails, this added frame component introduces a triangulated construction that assures a much stronger and more rigid forward frame structure. This highly rigid design also plays a significant role in the SH300i’s excellent handling characteristics and stability. This design innovation also maintains a compact front housing configuration that leaves plenty of leg and foot room for the rider.
To ensure easy manoeuvrability in tight urban traffic situations, the SH300i was also specially designed with the shortest wheelbase in its displacement class at 1,420mm. This shorter wheelbase also contributes to the SH300i’s swift, sure handling and light control at highway speeds as well. To help maintain confident control and reassuring handling at high motorway speeds, the new SH300i has also been equipped with an innovative new floating swingarm linkage system that smoothly and precisely controls rear wheel motion to minimise its influence on handling, thus assuring easy high-speed handling even with the SH300i’s relatively short wheelbase.
Floating Link Unit Swingarm
Another highlight of the SH300i’s innovative chassis design can be found in its highly advanced unit swingarm configuration. This system uses an innovative new three-piece articulating linkage to effectively isolate the main frame and rider from road and engine vibration. Significantly, this new floating link also maintains optimal lateral and torsional rigidity for precise handling, especially at the higher speeds the SH300i is easily capable of reaching.
Most modern scooters incorporate their engines into the structure of the rear swingarm as a complete assembled unit. This engine/swingarm unit is usually joined to the main structure of the frame by a single swingarm pivot and supported at the rear by either one or two dampers that absorb most of the bumps of the road.
However, this direct connection of the unit swingarm to the frame tends to transmit a significant portion of both rear wheel shocks and engine vibration through the swingarm pivot to the frame and rider.
One might think that a simple way to reduce this shock and vibration would be to soften the suspension damping or even introduce some damping material at the joint where the swingarm meets the frame. However, while the resulting ‘softer ride’ could conceivably prove effective in enhancing one facet of riding comfort, it could also have quite an unsettling effect on handling, especially at higher speeds.
Setting the goal of achieving a smoother, softer ride while still maintaining the firm torsional rigidity required for sharply responsive handling and confident high-speed control, the SH300i’s development team came up with a highly innovative solution. A new multi-jointed ‘floating’ swingarm link that effectively isolates the frame from most of the shocks and vibration produced at the rear wheel and from the vibration produced by the unit swingarm-mounted engine.
Floating Link System Composition
The SH300i’s three-piece articulating floating link system hangs from a single pivot point under the back of the lower frame. A large yoke section reaches directly back from the first pivoting hanger and surrounds the engine’s unit swingarm pivot. Finally, reaching up from the swingarm pivot is a short swing rod, which connects directly to the side of the engine by way of large vibration-damping rubber bushings.
The combination of these three linked and articulating joints permits a measured degree of free fore-and-aft engine and swingarm movement that minimises the transmission of rear wheel shocks and vibration to the frame. It also effectively isolates most of the engine’s primary vibration, which is generated along the same longitudinal axis.
Rubber bushings used in the attachment of the vertical swing rod to the engine also permit a small amount of vertical engine and swingarm pivot movement that helps damp out vibration in this axis as well.
In the horizontal axis, however, the floating link system’s combination of three linked parallel pivot points, which utilise both needle roller bearings and rubber bushings, provides a solid brace against the twisting lateral movement of the unit swingarm to ensure excellent lateral and torsional rigidity that results in remarkably precise and confident handling control, even while allowing a degree of free fore-and-aft movement.
This new floating link system also has the added benefit of lowering the height of the swingarm pivot compared to conventional scooter unit swingarm designs, thus permitting the SH300i’s dual-damper suspension system to more effectively absorb the vast majority of vertical swingarm movement, rather than allowing it to be transmitted through to the frame through a higher pivot point geometry, resulting in smoother and more stable handling.
Suspension Systems
Another contributing factor to the SH300i’s precise and responsive handling is its smoothly compliant suspension systems. Up front, a sturdy motorcycle-type 35mm-diameter telescopic fork like that featured on all of Honda’s latest high-performance scooters provides smoothly responsive bump absorption combined with swift and sure control, while a pair of dual conventional dampers take up duty in the rear to complement the new floating link swingarm pivot with 95mm of progressive damping for a pleasantly smooth and controlled ride, as well as remarkably sporty tracking and cornering control. Featuring 5-step adjustable spring preload, these dampers enhance riding confidence and high-speed handling, especially when fully loaded with a passenger and carrier-mounted top box.
Like its smaller predecessor, the SH300i rolls on large, lightweight 16-inch-diameter cast aluminium wheels. Both feature a distinctive 6-spoke pattern that complements SH’s slim, attractively curved bodywork for a look of elegant urban style. These wheels also mount wide-bodied, low-profile 110/70–16 front and 130/70–16 rear tubeless tyres that provide sure, responsive control and enhance riding comfort over virtually all road surfaces and riding conditions the new SH300i may encounter.
Easy-Operation Combined Brake System
Like many others models in Honda’s extensive motorcycle and scooter lineups, the SH300i comes fully equipped with Honda’s exclusive Combined Brake System, which links its front and rear disc brakes together for an optimised balance of braking control that significantly enhances riding confidence. This well-proven system features a single Combined three-piston front brake calliper gripping a large-diameter 256mm rotor between sintered metal pads for reassuringly strong braking control. At the rear, a compact single-piston calliper stops another 256mm rotor.
Like most conventional motorcycle brake systems, the right-side brake lever controls the two outer pistons of the three-piston front brake calliper to provide strong and sure braking control. The left-side brake lever, however, not only controls the rear brake, it also directs a carefully regulated level of braking force to the centre piston of the three-piston front brake calliper by way of a delay valve. This system thus provides a more efficient and smoothly controlled balance of front and rear braking forces when only the left-side lever is used. In operation the rear calliper engages first, followed soon thereafter by the engagement of the front calliper, for a more smooth and effective range of braking response. When both levers are used, the SH300i provides a smoothly responsive balance of braking control that brings it to a swift and calmly assured stop.
Combined ABS Version Also Available
The new SH300i will also be made available in an ABS version equipped with Honda’s lightweight, smooth and efficient Antilock Brake System as a welcome complement to its standard equipped Combined Brake System. Like the ABS featured on several other recent Honda motorcycle models, this highly advanced system provides exceptionally smooth and confidence-inspiring braking control in the most extreme braking conditions, where riders of all skill levels need it most.
At the heart of this system is a single, ultra-compact hydraulic modulator that controls the operation of both front and rear brakes, and is overseen by a high-speed computerised electronic control unit (ECU). The ECU constantly monitors a pair of small Hall-effect sensors that track and compare the rotating speeds of louvered pulsar rings attached to the centre of each wheels.
The slightest hint of tyre slippage, which registers as minute fluctuations in the relative speeds of the front and rear wheels—and is usually far too small for riders to detect—causes the ECU to activate the modulator with a rapid cycling of brake pressure Decrease-Hold-Increase micro-intervals that continue to apply just enough brake pressure to provide smooth and steady deceleration, but without allowing either the front or rear wheel to lock up, slip and lose control. All this happens so quickly that the system effectively stops tyre slip before it begins.
Demonstrating Honda’s firm commitment to advanced braking systems, the SH300i’s Combined ABS system represents one of the simplest and most effective such systems in motorcycling, providing the ultimate in riding confidence and control. Over variable traction surfaces, such as wet crossing lines, cobblestone streets or metal plates, this extra level of braking control can make all the difference in maximising a rider’s confidence and overall sense of security, and is sure to be a welcome feature for riders who have not fully developed the polished skills and confidence to operate the SH300i’s brakes to their full potential.
As with all other Honda models equipped with this Antilock Brake System, the control system’s main ECU features a self-diagnostic programme which constantly monitors all main electronic and hydraulic system components. If any malfunction is detected, the system automatically shuts itself off and reverts to the SH’s standard, fully operational Combined brake system, while a red LED warning light on the instrument console provides a visible indication of system failure and the need for timely service. |
| | | back to top | | | | Equipment | | | | Sleekly Styled Instrument Panel
The SH300i’s attractive, large-face instrument panel is cleanly and elegantly integrated into the top of its steering head, and features a more precise and minutely detailed design that provides a constant reminder of Honda’s unerring attention to the smallest detail. Its large, easy-to-read central speedometer is surrounded by coolant temperature and fuel gauges, and the whole assembly is recessed behind an attractively styled, resin-framed clear plastic lens. Indicator lights and a large LCD digital clock and dual-trip meter are positioned in easy view atop the handlebars.
Honda Ignition Security System (HISS)
Like most late-model Honda motorcycles and top line scooters, the SH300i features the highly effective HISS anti-theft security to ward off potential thieves and joyriders by preventing the engine from being started by any other than its two original keys. Since HISS disables the engine at the heart of its ignition system, it cannot be bypassed by either hot-wiring the ignition or exchanging the ignition switch module, thus rendering impossible one of the most common types of vehicle theft, that of being ridden away.
Under-Seat Carrying Space
Like the SH150i/SH125i before it, the SH300i features a compact carrying space under its locking tilt-up seat which opens at the turn of the ignition key and offers welcome carrying convenience and a secure place to store one’s helmet. Designed to hold one of the wide variety of popular stylish ‘semi-jet’ helmets available, this space also provides ample room for other travelling essentials, as well as a bit of light shopping whenever the need arises.
Up front, a slim locking glovebox opens to offer space for such small essentials as gloves, papers and other articles, and even features a utility socket for charging or powering such electrical accessories as a mobile phone. Shopping bags and other bulky items with handles or straps can be easily and securely hung in front, between the rider’s legs, from a convenient spring-loaded carrying hook.
Compact Rear Carrier
Behind the SH300i’s spacious seat sits a compact moulded resin rear carrier that doubles as a comfortable hand grip for pillion passengers. As featured on its smaller sibling, the SH150i/SH125i, this carrier is specially designed with moulded-in attachment points to allow for quick and easy mounting of a specially designed and colour-matched 35-litre top box (optionally available), which quickly and easily clips directly onto the carrier and can be secured with a key. No other mounting hardware is required. |
| | | back to top | | | | Optional Equipment | | | | The SH300i will be supplied with an impressive selection of optional parts and accessories to further broaden its range of operating versatility while complementing its cosmopolitan style. These parts include:
Wide-Coverage Bolt-On Windscreen
A handsome clear plastic bolt-on windscreen offers a broad area of protective comfort from gusts of onrushing wind, as well as bugs and flying debris. Its lightweight yet tough polycarbonate construction offers superior strength and resistance to chipping and scratches. The kit also includes a set of knuckle visors to assure good handling and driveability while enhancing riding comfort on cold days.
Specially Designed Top Box
A stylish 35-litre top-box has also been specially designed for easy mounting on the SH300i’s matching rear carrier. Painted in matching colours, this unique top box mounts and detaches with the flip of a single lever. No other mounting hardware is required.
Heated Hand Grip Kit
Heated hand grips with adjustable thermostat control and Honda-engineered battery-protection circuitry to help prevent excessive battery-power drainage when the grips are in use.
AVERTO Alarm system
This system features a vibration-sensitive electronic anti-theft alarm that warns off vandals and potential thieves with a penetrating high-decibel shriek. |
