Yamaha YZ250F

Lighter, faster, quicker: the ultimate YZ

The 2014 model is a completely new beast and we are ready to free our fuel injected racing machine to decimate tracks across the globe.

After several careful years in making the forward-positioned straight intake, rearward slanted cylinder and 'snaking' exhaust system has arrived. Housing the growling engine developed through Grand Prix is a brand new chassis helping to drop weight even further and centralise the riding sensation for a powerful off-road experience. This is the ultimate.

Without a doubt the 2014 YZ250F is Yamaha’s most responsive, useable and thrilling 250cc machine to materialise from the assembly lines in Iwata.
