This one has had the engine rebuilt in our service dept, both the top, and the bottom end. New chain, and sprockets too. The front suspension is all rebuilt also. This was the time that the factorys "joined forces". The joint effort between Kawasaki and Suzuki to design and develop the green 250cc four-stroke motocross machine brought together the best ideas from both companies. Independent efforts by Kawasaki and Suzuki to develop a machine for this category came together after Kawasaki and Suzuki formed the “Alliance” (sounds like something out of Star Wars, doesn’t it?). in the end, the basic engine design came from Suzuki, while Kawasaki contributed the chassis (including a new version of its now famous perimeter frame), suspension and bodywork. Kawasaki also had primary responsibility for testing and evaluation of the product during its development phase. As the identical machines roll off the assembly line, some receive green plastic, while others receive yellow plastic.
The four-stroke, 250cc double-overhead cam, four-valve engine has been rebuilt. Like everything else on the bike, the engine is designed to be compact and lightweight.
The motor features titanium valves (31mm intake and 25mm exhaust), a titanium header pipe, and magnesium head, generator and clutch covers. This one has an aftermarket pipe on it too. The motor also features some innovative designs to reduce pumping losses (important in a four-stroke) and vent crank case pressure to the atmosphere. With a five-speed transmission, the motor is fed its fuel/air mixture by a Keihin FCR carburetor, and ignition is controlled by a sophisticated CDI unit with 3D mapping. These bikes are a blast to ride!! Rebuilt engine, front suspension and the every thing else has been fully serviced, Ready to ride off road, the KX250F is!!
