FEATURES AND BENEFITS ENGINE High performance 2-stroke engine Ultimate development of the legendary KX250 2-stroke engine. Kawasaki Integrated Powervalve System KIPS varies the exhaust port height to broaden the useful rpm range for good low end and mid-range without sacrificing the top-end power. Kawasaki Throttle Responsive Ignition Control (K-TRIC) A throttle position sensor communicates load to the igniter so its micro computer can maximise ignition timing and power jet settings for quicker throttle response and maximum power. Fuel system Keihin Power Jet PWK38S carburettor gives excellent performance and response across the rev range. Digital Capacitor Discharge Ignition (CDI) Single spark system with acceleration compensator provides ideal ignition timing, especially under hard acceleration. TRANSMISSION 5-speed transmission Lightweight, compact and reliable 5-speed transmission. A ratchet-type shift mechanism for excellent shift response and feel. CHASSIS High-tensile steel perimeter frame High footpeg design improves riding position and increases the bank angle and ground clearance. Inverted 48 mm front fork 48 mm inverted twin chamber type fork with 16 way compression and rebound damping adjustment. Uni-Trak ® rear suspension Uni-Trak ® rear suspension offers superb traction and smooth suspension action across the whole stroke in a lightweight and compact suspension package. 18 way (low-speed), 2 turns (high-speed) compression and 16 way rebound damping with spring preload adjustment to tune suspension to all conditions. Front and rear disc brakes A single 250 mm semi floating front disc with twin piston caliper and a single 240 mm rear disc with single piston caliper ensure excellent stopping power and feel. Petal shaped brake discs are used on the front and rear. The wave shape helps clean the brake pads and reduces unsprung weight. Solid petal discs are available as an option for wet races. Wheels Front and rear DID rims feature an extremely light weight design to reduce unpsrung weight. Detail features A flat seat shape improves rider mobility while the two tone urethane material has the top textured for grip, and smooth sides for movement. Works style aluminium Renthal straight handlebar contributes to weight reduction. On the fly clutch adjuster allows mid race adjustments.
