Engine/Drivetrain

- Liquid-cooled DOHC 16-valve 998cc four-stroke inline four-cylinder engine
features bore and stroke dimensions of 75mm x 56.5mm.

- Sixteen-valve cylinder head features 29mm intake and 24mm exhaust valves
with an 12.2:1 compression ratio for efficient combustion and high horsepower.

- Lightweight nutless connecting rods.

- Direct shim-under-bucket valve actuation system ensures high-rpm durability
and allows 16,000-mile valve maintenance intervals.

- Iridium-tip spark plugs improve fuel combustion and performance.

- Dual Stage Fuel Injection (DSFI) system features two injectors per cylinder--one
upper and one lower--controlled by an ECU that senses rpm and throttle opening.
Lower injector enhances rideability while upper injector improves top-end
horsepower. At lower rpm only the lower injector is working. At higher rpm,
both injectors are activated. The system uses 44mm throttle bodies.

- Denso injectors with lightweight valving for faster reaction time and 12
holes per injector improve atomization of fuel mixture for optimum combustion
efficiency and power.

- Auto-enriching system is integrated into PGM-FI module, eliminating the
need for a manual choke.

- Forged aluminum pistons with moly surface treatment for reduced friction.

- Aluminum composite cylinder sleeves are high-pressure-formed from sintered
aluminum powder impregnated with ceramic and graphite. The lightweight composite
sleeves provide better wear resistance and superior heat dissipation compared
to conventional sleeves.

- Electronic ECU provides two digital 3-D fuel injection maps for each cylinder
and two digital 3-D ignition maps for cylinder pairs, creating ideal fuel
mixture and spark advance settings for superb rideability.

- Newly designed ram-air system allows higher volume of cool air to the 8.35-liter
airbox for linear power delivery and incredible engine performance.

- Stainless steel four-into-two-into-one center-up exhaust with twin outlets
and titanium core increases lean angle and reduces wind drag.

- Liquid-cooled aluminum oil cooler is lightweight and efficient.

- Maintenance-free automatic cam-chain tensioner.

- Starter gears located on the right side to produce narrow engine and increased
lean angle.

- Eight-plate clutch is compact and tough, featuring durable friction plate
material.

- Cassette-type, close-ratio six-speed transmission is easily accessible
for rapid gear ratio changes and maintenance at the race track.

- Durable #530 O-ring-sealed drive chain.
