           The KX design philosophy – to put mid-level to expert riders on the top step of the podium – has not changed since the brand was launched over 40 years ago. The KX250F has a history of winning: in the extremely competitive 4-stroke 250cc class it is the racer with the most AMA Supercross and Motocross titles. Adding to its highly acclaimed engine and chassis performance, numerous industry firsts and advanced technology, the 2017 model offers a more powerful engine, a significantly lighter chassis, and slimmer ergonomics, making the new model the fastest KX250F yet. In fact, the new model gets around the track 1.6 seconds quicker* than its predecessor.
