The 2008 Yamaha YFZ450R is a pure sport quad, engineered to deliver the ultimate performance on the dirt track, drawing its cues from the MX world. It boasts a hybrid aluminium chassis for reduced weight and flex, but which is extremely strong, dramatically improving cornering and precise tracking at high speed.

The 5-valve DOHC engine is placed low in the frame for better mass centralization, a great match for the slightly wider profile and revised suspension geometry, all ensuring a performance boost in the hands of the skilled rider. Wide foot pegs and a redesigned seat provide excellent support in tight turns and when landing a hard one.
