About Yamaha YZ250F

A masterpiece in the motocross category, the Yamaha YZ250F was first released by Yamaha in 2001. The initial model had a four-stroke DOHC engine supplemented which was five-valve. Yamaha then went with a steel structure for the frame, which later got replaced by an alloy frame. Yamaha changed the structure in 2006, and since then, every year Yamaha YZ250F comes with an alloy frame.

Later enhancement took place in 2008 when Yamaha changed the engine. To make the performance even better, Yamaha introduced a new engine layout in 2010. This layout helped the bike to have a low center of gravity for outstanding balance, something Yamaha YZ250F is highly praised for.

These additions made the bike extremely powerful on the track. Similarly, in 2019, Yamaha installed an electric starter to the Yamaha YZ250F for an easy starting experience.
