Yamaha YZ250F

Extended Description

Motocross races are won or lost in the turns – that’s why, from the ground up, the YZ250F has been designed for exceptional cornering. Perfectly balanced, a lightweight aluminium frame turns effortlessly on the approach to every bend. And, with more linear power delivery through the rev-range, the revised 4-stroke DOHC 5-valve engine lets you power out of the exit.

At the same time, the bike’s responsive suspension gives feedback on the traction while smoothing over the bumps. On and off the track, the YZ250F’s poise and agility are reflected in its sleek styling and its compact, dart-like shape. In every way, the YZ250F leaves the competition behind.
•Lightweight Bilateral Beam aluminium frame
•Improved mass-centralisation for better handling
•4-stroke DOHC single-cylinder 250cc 5-valve engine
•Long-stroke suspension for traction and road feel
•New generation competition styling
