1988 Kawasaki KR-1 - 55PS of 250cc 2-stroke 225km/h racer

1988-Kawasaki-KR-1 1988 sees a lot of 250cc 2-stroke performance bike on the market. One of the best bike are this one, Kawasaki KR-1. Fitted with liquid-cooled 2-stroke 250cc engine 180° firing parallel twin configuration, this engine are able to maxes out 55PS  of power at 11,000RPM and have been tested at the Bonneville Speedway to claim the World's Fastest Production 250cc as tested by Performance Bikes Magazine. The speed recorded is 225km/h. That is fast for a bike with just 123kg of weight. Kawasaki Integrated Powervalve System (KIPS) was incorporated in the engine design to widens the power delivery of the engine so that it feels smooth in almost every RPM range. KIPS are still used in the current bike in 2013 as used by the KRR-150ZX.

Is there any of this bike available in Malaysia? Or is it never touch the ground here?
