YFZ450R

YFZ450R - Race ahead: the number1 racing ATV.

The YFZ450R is the number one choice of racers. And one look at the specification tells you why. The result of a decade of race-winning experience, it’s a total package of sharp-handling, tight suspension and a high-tech engine.

Agile and nimble, competitive performance is what it’s all about. The fast-spinning, 5-valve DOHC 449cc engine is held low in the rigid, lightweight hybrid chassis, while long-travel suspension and a wide track contribute to the overall balance.

The 32-bit fuel injected engine, gearbox, clutch and exhaust deliver the perfect combination of hole-shot acceleration and smooth power – right through the rev range.
