• Class-leading power-to-weight
ratio for outstanding acceleration and handling.
• Smaller, lighter, more compact inline
four-cylinder engine. • Improved
midrange performance and enhanced peak power.
• Significant weight reduction in
engine and chassis. • Repositioned
transmission shafts within crankcase allow
for shorter engine. • New lightweight
forged-aluminum pistons incorporate special
shot peening for added toughness. •
Lightweight magnesium head cover. •
New single exhaust-valve springs. •
Smaller, lighter neodymium magnet within
alternator. • New transmission
gear ratios. • Smaller, lighter
clutch. • New front-brake vertical-piston
master-cylinder system. • Lighter
weight stainless steel four-into-one exhaust
features new inline-exhaust valve to control
exhaust pressure for maximum performance.
• New intake-air control valve (IACV)
minimizes torque reaction and smoothes response
to small throttle changes through gradual
reductions of air and fuel intake when the
throttle is opened and closed. •
New non-resonance knock sensor maintains
optimum spark advance while constantly monitoring
combustion performance during midto high-speed
operation. • New nose-mounted
ram-air induction directs fresh, cool air
to a higher-volume airbox. • New
smaller and lighter Honda Electronic Steering
Damper (HESD). • Newly designed
Fine Die-Cast (FDC) frame uses four large
castings for lighter weight. •
Improved mass centralization. •
Redesigned radiator with compact dimensions
improves cooling capacity. • All-new
bodywork enhances handling and performance.
• Handlebars raised 10mm for improved
rider comfort. • Centre of gravity
revised for more neutral response and easier
side-to-side flickability. • New
compact instrument design.
Engine/Drivetrain
• New liquid-cooled
DOHC 16-valve 599cc four-stroke inline four-cylinder
engine features oversquare bore and stroke
of 67mm x 42.5mm. • High-revving
engine redlines at 15,000 rpm. •
Intake port surface treatment revised for
improved efficiency. • Oil jet
relocated beneath piston for additional
friction reduction and cooling. •
Iridium-tip sparkplugs improve fuel combustion
and performance. • DSFI system
features 40mm throttle bodies and two injectors
per cylinder — one upper and one lower
— controlled by an electronic control
system (ECU) that senses rpm and throttle
opening. Lower injector enhances rideability
while upper injector improves top-end horsepower.
• Denso 12-hole injectors deliver
finely atomized fuel mixture for optimum
combustion efficiency and power. •
Auto enrichment system is integrated into
programmed fuel injection (PGM-FI) module,
eliminating the need for a manual choke.
• Two-stage ram-air system provides
high volume of cool air to the airbox for
linear power delivery and incredible engine
performance. • Cylinder head features
angled valve insets to improve airflow.
• Cylinder head features two springs
per intake valve and one spring per exhaust
valve for optimum high-rpm valve operation
and durability. • Direct shim-under-bucket
valve actuation ensures high-rpm performance
and durability. • Lighter pistons
and lighter, nutless connecting rods contribute
to quicker acceleration. • Double-pivot
tensioner for cam-chain durability.
• Right-side starter gears allow increased
lean angle. • Smooth-shifting
close-ratio six-speed transmission with
new gear ratios is closely matched to the
engine's powerband. • MotoGP-style
RC211V centre-up exhaust system.
Chassis/Suspension
• 41mm inverted HMAS
cartridge front fork features spring preload,
rebound and compression damping adjustability
for precise action. • Unit Pro-Link
rear suspension system is patterned after
RC211V GP racer. In this two-piece shock
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 from being transmitted into the frame,
allowing optimum frame rigidity and improved
rideability out of corners. •
Braking system features twin four-piston
radial-mounted front calipers, dual 310mm
front discs and a single 220mm rear disc
for optimum stopping power. •
New vertical-piston master-cylinder system
produces superior leverage ratio at the
front brake lever for higher braking efficiency
with excellent feel and controllability.
This layout permits the use of a longer
brake lever, which means more braking force
with less effort from the rider. •
Lighter aluminum steering stem.
Additional Features
• Industry-leading
ergonomic design features maximum rider
comfort for minimum fatigue in all riding
conditions. • Centrally mounted
fuel tank is positioned low in the frame,
increasing mass centralization and allowing
a more compact design. • Plastic
tank shell cover protects tank and airbox.
• Line-beam headlights feature three-piece
reflector design utilizing two H7 bulbs
for optimum light distribution and a unique
compact design. • New instrumentation
is very compact and features LCD panel with
tachometer, odometer, twin tripmeters speedometer,
fuel gauge and clock. • Attractive
hollow-spoke aluminum-alloy wheels feature
race-spec 3.5 x 17-inch front and 5.5 x
17-inch rear dimensions. • One-piece
fan assembly for maximum cooling efficiency.
• Maintenance-free battery. •
Optional seat cowl. • Compact
rear cowl storage compartment for U-type
locking devices (lock not included) under
the passenger seat. • Pivoting,
aerodynamic mirrors. • Integrated
ignition-switch/fork lock for added security.
• Convenient push-to-cancel turn-signal
switch. • Transferable one-year,
unlimited mileage limited warranty
