Lightweight, ceramic composite plated aluminum cylinder. reduced weight... no sleeve or heavy liner... plating is sprayed directly on the aluminum block ceramic coating insures faster, more uniform heat dissipation coating enhances the thin film of oil between the cylinder & piston, reducing friction & increasing power Cylinder is offset relative to the crankshaft (to exhaust side) reduces frictional losses between piston & cylinder wall during the power stroke Cylinder cutaways allow air trapped under the piston to enter a side chamber (or cutaway). reduces horsepower-robbing pumping losses Crankcase also utilizes special cutaways reduces horsepower-robbing pumping losses crankcase cutaways match cylinder cutaways for maximum efficiency Lightweight, short-skirt, forged aluminum piston. lightweight design means faster throttle response reduced mechanical vibration for excellent durability special coating on piston skirt reduces friction Piston oil cooler jet nozzle directs oil to the cylinder, rod & underside of piston. reduces piston, cylinder & rod temperatures for excellent durability Carburized (type of heat treatment) connecting rod for excellent durability. Lightweight gear driven balancer shaft. reduces vibration for improved rider comfort & reduces rider fatigue 5-speed transmission utilizes a 2-bar, floating shift guide system & a 14 mm shift shaft. smooth, positive shifts good durability in the event of a crash (14 mm shift shaft) see spec page for gear ratios Heavy duty, multi-plate, clutch with quick access magnesium outer cover. quick access outer cover provides fast & easy clutch access light lever pull for reduced hand fatigue 44mm Keihin throttle body fuel injection system. 12-hole injector maximizes fuel atomization for more complete combustion & excellent power delivery FI benefits include automatic adjustments to insure the optimum fuel - air ratio regardless of outside air temperature & altitude other benefits include excellent starting & excellent throttle response cold start knob also doubles as an idle adjuster The injector spray pattern, spray direction and the distance to the intake valves have been optimized. Forward mounted straight intake tract helps to maximize the benefits of the FI system & overall power output. Optional, compact, hand held GYTR Power Tuner allows tailoring of both fuel injection duration & ignition mapping. 9- different setting points can be accessed for both fuel duration & ignition maps maps can be stored & shared with other Power Tuners if desired easy access GYTR Power Tuner connector port Revised forward mounted air box with washable, dual stage foam air filter. No tools required to access air filter new air box cover & new quick release fastners washable design reduces maintenance costs Wet sump lubrication system. reduces weight (no remote oil tank or oil lines) eases maintenance (easier & faster oil changes) oil volume is optimized to reduce oil related drag & weight Easy access cartridge-type oil filter. Compact, lightweight, single core, dual radiators provide outstanding cooling efficiency. Maintenance-free transistor controlled ignition (TCI). produces a strong spark for fast starts provides precise ignition timing / mapping for optimum engine performance at all rpms High capacity AC magneto to power the FI system. Lightweight, wrap-around exhaust system. exhaust exits from the rear of the cylinder & circles cylinder body design ensures the optimum tuned header length maximizes exhaust pulse effect for excellent power delivery centralizes mass by moving weight closer to the centre of the chassis Lightweight, aluminum, re-packable muffler (aka silencer). revised muffler bracket reduces weight sound output is 94 dB meeting CMRC & AMA regulations Launch control system (LCS). provides smoother, quicker starts with less wheel spin & front wheel lift allows rider to concentrate on clutch control, body position & machine system functions in 1st & 2nd gears only and is disabled as soon as the bike is shifted into 3rd gear ECU controls the system and adjusts rpm to limit wheel spin & wheelies activation button is on the LHS handlebar & features a LED indicator light. Special G sensor system shuts down fuel injection system if bike lies on its side for more than 10 seconds helps prevent costly engine damage no special procedure to re-start the bike... just kick it and go. Works-style race-spec barrel adjuster for on-the-fly clutch lever free play adjustments. CHASSIS/SUSPENSION Compact, lightweight Bilateral Beam aluminum frame. centralizes mass for exceptional handling & manoeuvrability frame offers an optimum rigidity balance between strength, rigidity & tuned flex, plus excellent shock absorbing qualities frame design offers excellent rider - machine communication (a.k.a. feedback) key goal of the chassis is fast & easy cornering ... one of the main keys to winning races Lightweight, tapered aluminum swingarm. lightweight design reduces unsprung weight for optimum suspension performance excellent rear wheel traction & control 25mm rear axle Lightweight detachable rear sub frame. constructed of square-section, lightweight aluminum pipe with no bends allows easy access when servicing rear suspension components detachable design reduces costs in the event of a loop out Adjustable handlebar holders offer a total of 4 different handlebar positions with an adjustment range of 30mm. suits wide variety of rider sizes handlebar holders are rubber mounted for reduced vibration & improved rider comfort 48mm, adjustable, inverted, Kayaba SSS cartridge fork with 310mm (12.2) of wheel travel. front fork adjustments include: 20-way compression damping & 20-way rebound damping inner tubes feature a special friction reducing coating 22 mm front axle optional fork springs are available through Genuine Yamaha parts Fork features a twin-chamber, Speed Sensitive System design damper unit is in a separate structure (completely separated air & oil chambers) helps prevent aerated fork oil from entering the inner damper assembly & degrading its damping abilities since the inner damper is pressurized, it also eliminates bubbles forming in the oil.
