2009 Honda CRF450X


Closely based on the high-flying big-bore CRF450R, the enduro-focused CRF450X has been claiming victories in the off-road arena since it first appeared on trails across the world.

Featuring awesome power and a slim, easy-to-ride form, it takes off-road riding to exhilarating peaks of fun and excitement. Its rugged, long-travel suspension systems are augmented by the Honda Progressive Steering Damper (HPSD), which eases control and smoothes handling in cornering and over rugged terrain.

Are you chasing the ultimate accolade, or searching for the incomparable thrills that come from cutting loose on an amazing new cross country trail? The mighty CRF450X is the definitive tool to give you both the adrenaline and the stamina to push your own limits time and time again, and keep you coming back for more.
