KX 250
Designed to continue its history of winning the 2020 model KX250 features a new engine with increased power, an even more potent high-rpm range, and a higher rev limit. Complemented by a lightweight, well-balanced chassis with a new fork and stronger brakes, this performance advantage translates to quicker lap times, making it the quickest KX250 to date.
