SUPER-RESPONSIVE , 2-STROKE RACING ENGINE
*The high-performance 84cc liquid-cooled 2-stroke engine features the Kawasaki Integrated Power-valve
®
System (KIPS ) that varies exhaust port height for increased horsepower and torque.
Maximum power of 21.0 kW {28.5 PS}is produced at 12,000 rpm.
Maximum torque is 17.2 N-m at 11,000 rpm.
The cylinder is Electrofusion plated for efficient seizure resistance, heat transfer and long wear.
A Keihin PWK 28 semi-flat slide carburettor positions the nozzle jet close to the cylinder for sharp response
across the rev range.
The intake system is controlled by piston port design using 2-petal type carbon fibre reeds for quick
response and durability.
Precise, digital CDI ignition delivers a hot spark and reliable ignition.
The large air intake on the right side of the airbox improves airflow to the air cleaner. Filter maintenance is
simple.
Transmission
Race proven 6-speed manual gearbox with ratios chosen to deliver optimum performance.
The wet type multi-disc clutch is designed to survive the tough environment of motocross competition.

among the best in class. The lightweight chassis is designed to take years
of competition without failure.
The 36 mm upside-down front forks deliver sharp handling and smooth

features a remote-reservoir gas charged shock that is fully adjustable for
spring preload, compression and rebound damping.The sturdy race
developed swingarm delivers good handling performance over rough
