Segment: Enduro/Offroad
Production years: 2005, 2006
The YZ450F is the flagship off-road bike in Yamaha's 2005 line-up and it comes as an all-new machine, with a new engine, new frame and obviously, a new transmission. The YZ450F was improved in all sectors, from the high-performance, hi-revving titanium valves to the new intake, modified inclination angle for the cylinder, a more centralized mass and easier servicing.
Multiple works' style features have also been implemented, and the 2005 YZ450F is ready to take on the roughest tracks and help you start gathering trophies. Suspensions have not been overlooked, with revalving adding more precision to the ground tracking job and offering better directional control.
