This is the bike that has totally revolutionized the 250 class. With its radical reverse cylinder head, rearward sloping cylinder and underseat fuel tank, the YZ250F is the way ahead for motocross design.
Shortly after its debut this bike took AMA 250 Supercross and Motocross titles, as well as a WMX world crown and multiple GP race wins. And to underline Yamaha's policy of continuous development, we've made a range of technical improvements designed to keep the YZ250F on top.
Featuring important new engine, transmission and chassis changes, the latest YZ250F is built to give even better performance and useability, making it the bike of choice for amateurs and pro riders.
