t might not have been a match made in heaven, but the alliance between Kawasaki and Suzuki got at least one thing accomplished: It got the two manufacturers on the 250F boat before it left the dock with just the Yamaha and Honda on board. As far as the 250cc four-stroke is concerned, from a manufacturing point of view, the short-term joint venture between Kawasaki and Suzuki was a successful one, as the two companies combined efforts and resources to design and build a bike that went on to win five titles - all on green bikes - over the pre-agreed two-year marriage. But from a marketing point a view, things didn't go as smoothly. After all, how can two manufacturers take credit for race wins - or for championship titles, for that matter? So, as you can probably imagine, things got a little "weird" between the two companies. But things should start getting back to normal again now that the two manufacturers are going their own way in '06...well, sort of. While Kawasaki does have its own KX250F this year ('06), it will still produce the '06 RMZ250 for Suzuki, which we understand will be identical to the 'OS but with some changes to the motor. CWe expect Suzuki to have its very own 250cc four-stroke in '07.) So, even though the marriage is over, the two companies are still talking to each other. While Suzuki had its design team working on the RM-Z450 the past two years, the Kawasaki team instead focused its attention on it first purebred KX250F (and 450, as well), which, for all intents and purposes, has nothing in common with the previous KX250Fs. Few parts, if any, are interchangeable between the 'OS and '06 KX-Fs. In designing the new KX2S0F, Kawasaki had three objectives in mind: to have the most horsepower in class, a well-balanced chassis, and "superior" rear-wheel traction. As a result, the new KX250F got a complete overhaul, which Includes a new aluminum frame and a new suspension supplier.
