TECHNOLOGY
ENGINE
The right side of the airbox is cut back to increase airflow and draw airfrom behind the number plate as well as below the seat.
Quick revving, liquid cooled engine.
Kawasaki Integrated Power Valve System (KIPS) varies exhaust port height for increased horsepower and torque throughout the rev range.
Breather added to KIPS cover relieves exhaust pressure for more precise KIPS valve action contributing to improved high-rpm and overrun performance.
Electrofusion coating on the aluminum cylinder provides rapid heat transfer, superb wear resistance and optimum lubrication retention for increased performance and durability.
Keihin PWK28 carburetor features a crescent shaped slide that enables the needle to sit closer to the intake ports for quick throttle response.
Carbon fibre reeds aid throttle response. The carbon fiber weave of the reed valves is 45 degrees to the intake tract so that the reed is more flexible and correspondingly more responsive at lower rpm.
The right side of the airbox is cut back to increase airflow and draw air from behind the number plate as well as below the seat.
Digital Capacitor Discharge Ignition (CDI) precisely controls timing, no matter how fast the rpm changes.
Lighter magneto rotor uses powerful neodium (rare-earth) magnets to lower inertial moment from 6.3 kg/cm2 to 4.0 kg/cm2 which improves low-rpm response.
Tough 6-speed transmission has bushings added to 2nd, 3rd, and 4th gears on the output shaft for increased durability. Fifth and 6th gears on the transmission input shaft also ride on bushings.
The ends of the shift forks are hard-chrome finished for durability.
Thick base at the clutch housing fingers for increased durability.
The right hand engine cover provides a separate clutch cover for quick servicing at the track without removing the water pump.
Single radiator mounted on the right side keeps the engine cool during long motos.
CHASIS
High Tensile Steel Perimeter Frame combines narrow dimensions, steep rake angle and high rigidity for quick handling without sacrificing straight-line ability.
Bolt on tail section eases repairs and maintenance.
36mm inverted cartridge fork provides a progressive ride to better resist bottoming and fit larger and more aggressive riders.
Inverted forks are more rigid to provide better steering response and control.
Fork compression damping is 18-click adjustable and the cartridge design means better action.
The aluminum upper fork tubes measure 49.5mm in diameter for flex free performance.
Uni-Trak rear suspension settings provide a progressive ride to better resist bottoming and accommodate larger, more aggressive riders.
Fully adjustable rear shock spring preload, 4-click compression damping, and 16-click rebound damping allows the suspension to be tuned for specific conditions.
Mono-tone seat cover uses a high-grip top and smooth sides for good grip when sitting and high mobility when riding on the pegs.
Hydraulic front and rear disc brakes feature drilled discs for light weight.
