|More Information on the Kawasaki KR-1/KR-1S|
The KR-1 and KR-1S were motorcycles introduced in 1988 by Kawasaki Heavy Industries. The two-stroke motorcycles were replicas of their successful KR-250 road racing competition motorcycles.
In 1988, Kawasaki produced a road racing replica motorcycle. The initial models were the B1, B2 series of the KR-1. In 1989, due to the sales success and updated models of competing manufacturers (RGV, NSR, TZR) the KR-1 (B series) evolved into the KR-1S and KR-1R (C, D series). The C1, C2, C3 and D1, D2 models shared the same engine (minor updates) and bodywork (different colour schemes) of the previous KR-1. The S and R models differed slightly in construction of frame, wheels, brakes, and colour schemes.
The engine for all KR-1 models was a two-cylinder, reed valve induction two-stroke motor of 249 cc (somewhat based on the previous Yamaha TZ/TZR configurations). The 180° firing parallel twin configuration featured a crank driven balance shaft. The power delivery was broadened with the use of the Kawasaki Integrated Powervalve System (K.I.P.S.) arrangement shared by other Kawasaki two-strokes.
Total production of all models in KR-1 (B/C/D) series was less than 10,000 units worldwide. The low production numbers has increased collectibility. Worldwide markets for sales were Japan, United Kingdom, Europe, Australia, New Zealand, South Africa (excluded USA due to emissions restrictions). Considered to be least successful of the four Japanese 250 cc Race Replicas (in terms of sales), the KR-1 series was notable for excellent handling, due to its light weight and steering geometry and least difficult to modify and increase the power output of the engine. Proven to be fastest of all 250 cc models (Suzuki RGV250, Yamaha TZR250, Honda NSR250R, Aprilia RS250) with a top speed of 139 mph (225 km/h) - tested by Performance Bikes Magazine and subsequently at Bonneville Speedway (World's Fastest Production 250 cc)
The KR-1R (D1,D2 models) were sold only for the Japanese market for 599,000yen (559,000yen for S model)
In New Zealand, specifically for production racing, the Sports Production (SP/C3A) variant of the S model was produced. In very limited numbers, (less than 12 units) the SP was the based on a 'S' model and fitted with the 35 mm carburetors from the R model, and modified cylinder porting and compression ratio.
