An injection of hyperactivity.
Powered by a hardcore race-bred 5-valve 450cc engine and running a lightweight high-tech chassis with a wide track, the YFZ450R is the ultimate Sport ATV. This model is a sharply focused sport ATV that has dominated the competition scene for the last decade.
The YFZ450R now includes stronger high-speed power as well as a new slipper clutch and uprated suspension, to give the model an even more race-winning engine and chassis performance to keep the YFZ450R way out front.
Rider safety is our priority. This ATV should only be ridden by riders aged 16 years and older.

The fuel-injected 449cc now includes a range of modifications to improve the overall high rpm power feel, and deliver an even quicker and sharper throttle response.
The YFZ450R is equipped with an assist and slipper clutch - the first time that this design has been used on a sport ATV. The main benefit of this type of clutch is that it partially disengages when decelerating sharply and downshifting rapidly for corners, allowing the rider to control corner entry speed more precisely by using only the brakes.
High-specification front and rear shock absorbers offer an improved cushioning effect during the initial stages of compression to give a more comfortable ride, together with improved terrain following capabilities while reducing unsprung weight.
