If you ride motocross bikes and have been in high jumps, you know the often disconcerting hesitation that bikes have immediately after they land. The Kawasaki KX250F engine deals with this. The hesitation only lasts for a split-second, but nobody likes it, which is one of the reasons why this engine is so popular. It has a digital fuel injection, Keihin throttle body that transfers the power to the chain and your back wheel as soon as you need it. This engine was introduced in 2004. It is a liquid-cooled, four-stroke, four-valve engine. The initial models were made in a joint venture between Kawasaki and Suzuki, but the latest models are just Kawasaki. The digital fuel injection was added by Kawasaki, and they made the engine lighter to improve its performance. The engines are all 249 cc engines and have five-speed transmissions. There is a vast inventory of Kawasaki KX250F engine parts available on eBay. This includes KX250F engine guards and KX250F engine plugs, as well as crankcases, valves, and pistons. You can even get full engines if you want to do a complete swap.Shop the extensive inventory of motorcycle parts and Kawasaki motorcycle collectibles!
