Liquid-cooled DOHC
16-valve 998cc four-stroke inline
four-cylinder engine features bore
and stroke dimensions of 75mm x 56.5mm
for high-revving performance.
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 ensures high-rpm durability
and allows lengthy valve-maintenance
intervals.
Iridium-tip sparkplugs
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-litre airbox for linear
power delivery and incredible engine
performance.
Stainless steel four-into-two-into-one
underseat 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.
Aluminum-hybrid
rear swingarm is longest in class
for superior traction under hard acceleration.
Aluminum subframe
is lightweight and easily removed
for ease of maintenance.
Honda Electronic
Steering Damper (HESD) is a rotary
type steering damper that electronically
modulates steering damping based on
road speed and acceleration. An ECU
unit senses road speed and acceleration
and then sends a signal to a solenoid.
The solenoid controls an oil pressure
relief valve within the damper unit.
At slower speeds the relief valve
is open, allowing for a free flow
of oil through the damper unit, resulting
in reduced damping force and lighter
steering effort. At higher speeds
the flow of oil is restricted, resulting
in increased damping force and additional
stability. HESD is the first steering
damping system that makes it possible
to increase high-speed performance
while maintaining low-speed handling.
43mm inverted aluminum-slider
Honda Multi-Action System (HMAS) cartridge
front fork features spring preload,
rebound and compression damping adjustability,
and offers precise action and unparalleled
rigidity.
Unit Pro-Link rear
suspension system is patterned after
the RC211V MotoGP machine's. In this
system, the upper shock mount is contained
within the swingarm rather than the
frame. With no top frame-mount for
the shock, this unique system reduces
negative suspension energy being transmitted
into the frame, allowing optimum frame
rigidity and improved rideability
out of corners. The HMAS shock offers
rebound and compression damping and
spring preload adjustability.
Front brake system
features radial-mounted four-piston
calipers and 320mm floating discs,
and a 220mm rear disc with a single-piston
caliper for exceptional stopping power.
Super-light aluminum-alloy
hollow-spoke wheels feature race-spec
3.5 x 17-inch front and 6.0 x 17-inch
rear dimensions.
Centrally mounted
18.2-litre fuel tank is positioned
low in the frame, increasing mass
centralization and allowing a more
compact design. This design positions
the rider farther forward for optimum
handling.
Additional Features
High-capacity 350-watt AC generator.
High-tech instrument display features
tachometer, LCD readouts for speedometer,
coolant temperature, odometer, two
tripmeters and a clock. A low-fuel
LED light and shift indicator light
is located in the tachometer.
Line Beam Headlight features three-piece
reflector design utilizing two H7
bulbs for optimum light distribution
and unique compact design.
LED taillights for improved appearance.
Plastic tank shell cover protects
tank and airbox.
One-piece fan assembly increases
cooling efficiency.
