FEATURES & BENEFITS

Key Features

998cc Four-Cylinder, DOHC Engine

Very compact, narrow and lightweight design
The upper crankcase and cylinder are a one-piece casting, which is more than two pounds lighter than using a separate cylinder and offers increased rigidity. A slanted casting process rotates the piece during casting to eliminate imperfections and excess casting material
Channels in the case mounting surfaces route oil to various parts of the engine, eliminating oil lines and saving weight
Crank axis, input shaft and output shaft create a stacked triangular layout that reduces engine length and lowers the center of gravity
Narrow engine design allows excellent ground clearance for 52 degrees of lean angle
Round (not cam-shaped) throttle pulley provides low throttle resistance and combines with revised ECU mapping to provide linear transitional power characteristics when the rider gets back on the gas coming out of a turn. Ultra-fine atomizing fuel injectors aid combustion efficiency and power output
Lightweight Denso radiator has tightly packed cores for optimum cooling
A high-efficiency, liquid-cooled aluminum oil cooler uses specially designed internal fins to dissipate heat and cool the oil

Four-Valve Cylinder Head

Compact valve train reduces cylinder head height
Intake ports and coolant passages developed using flow analysis for efficient cylinder filling and more power, and maximum cooling efficiency
Camshafts are carved from forged chromoly billet, which is more than one-half pound lighter than cast cams. The cams and tappets are treated with soft nitriding to prevent galling and seizing with the aggressive, high lift profiles
Single valve springs with oval cross sections are light and lower to reduce overall cylinder head height
Forged sintered aluminum spring retainers are half the weight of steel retainers and allow higher rpm

Forged Pistons

Forged pistons are lighter, stronger and more heat resistant than cast versions. Flat-top design matches the compact combustion chamber and improves combustion efficiency

Ram Air Induction

Central ram air duct produces a straighter path to the airbox for maximum intake efficiency and provides the mounting surface for the instrument panel, eliminating brackets and weight
Flow analysis used to design efficient ducts to the airbox that also prevent water from reaching the air filter
Compact airbox and air cleaner are highly efficient and contribute to the compact riding position

TCBI Ignition with Digital Advance

Titanium Exhaust with Butterfly Valve

All-titanium system provides the ultimate light weight exhaust
Butterfly valve, located before the exhaust splits to the mufflers, is controlled by rpm, throttle position and gear position to improve low-end response and help smooth overall power. Optimum exhaust tuning is attained at all engine speeds to prevent blowback that can occur with high speed overlapping valve timing

Six-Speed Transmission

The splines on the transmission shafts are barrel ground so the gears slide smoothly for improved shift action
Close ratio transmission increases circuit performance
A back-torque limiting clutch automatically disengages the clutch under hard braking and deceleration to prevent rear wheel hop during corner entry. Optional springs, spring retainers and shims are available to fine-tune the clutch for specific conditions

Aluminum Twin Spar Backbone Frame

Combination of pressed and cast aluminum components are welded to form the twin-spar backbone-type frame. By combining cast and pressed pieces frame weight is kept to a minimum while still providing high strength and stability with responsive handling
Twin-spar backbone design provides 600cc class width
Die-cast, one-piece subframe is strong and light
Chassis features optimum center of gravity for easy roll response, this is particularly important when riding through a series of esses or returning to vertical as the rider exits a corner

Uni-Trak Rear Suspension

Short, compact frame allows the swingarm to be longer, which makes it easier to control rear wheel powerslides
Rear shock is fully adjustable for preload, compression and rebound damping. Ride height can be adjusted by adding/removing optional 1mm shims at the upper shock mount
Equipped with top-out spring that allows the rear wheel to better follow the road surface when the rear end is light due to hard braking
Small piggyback shock reservoir is designed to save weight

43mm Inverted Cartridge Front Fork

Kayaba 43mm inverted cartridge fork provides exceptional rigidity
Equipped with top-out springs which allow the front wheel to better follow the road surface when the front end is light due to hard acceleration
Stiff settings suitable for track use
Fully adjustable for preload, compression and rebound damping

Aluminum Wheels

Six-spoke cast aluminum wheels are practically as light as race-specific wheels. The six-spoke design requires much less material between spokes so that rim thickness is thinner and lighter

Radial Mounted Front Disc Brakes

Radial mounted 4-piston front brake calipers. Instead of mounting the calipers with threaded tabs cast near the top of the caliper, the radial design utilizes integrated mounting points at both the top and bottom of the caliper, with the mounting bolts inserted through the rear of the caliper instead of the side/front. This makes the caliper more rigid, which improves brake feel over a wider range of operation
A separate brake pad is used for each piston. One large pad tends to deform with the heat generated by hard track style riding, resulting in a loss of brake feel at the lever. Individual pads provide increased cooling efficiency and can absorb more heat without deforming so they maintain consistent brake feel lap after lap
Petal design brake discs offer excellent cooling and warp resistance

Radial-Pump Front Brake Master Cylinder

Aerodynamic Bodywork

Light and compact projector beam headlights allow a more aerodynamic fairing as well as a more efficient Ram Air duct
The fuel tank has a unique concave top that allows the rider to tuck in further and improve aerodynamics
The rear seat cowl improves airflow around the back of the ZX-10R, reducing turbulence and drag
The dual under-seat exhaust also serves to minimize drag by eliminating the turbulence associated with most mufflers
By integrating the front and rear turn signals into the fairing, wind resistance is further minimized.
Three-piece front fender designed for aero efficiency
Different color panels create a sporty, aggressive image
