Yamaha YZ450F

Lighter, faster, quicker – the ultimate YZ

Faster and more responsive, the 2014 YZ450F is the absolute peak of all our knowledge, experience and immense passion for off-road. This is the ultimate.

The new YZ450F has been overhauled to bring a razor edge to the strongest elements of the bike. The innovative fuel injected rearward-slanting single cylinder engine has been reworked for more usable power while the snaking exhaust pipe is just one of a raft of fresh features to centralise the weight of the motorcycle.

A brand new chassis further compacts the machine. A redesigned sub-frame, refined gear-shift system, a repositioned fuel tank along with slim and sleek plastics make this motorcycle a tractable weapon.
