YAMAHAYFZ450R 2011 - 2012
The 2011 Yamaha YFZ450R is an ATV created for heavy-duty exploitation on the motocross circuits and is loaded with a heap of features to make it fast, balanced, reliable and easy to handle. While this is definitely not a toy for beginners, it can double as an off-road fun machine in case riding on rough forest trails is among your preferences.
However, it's on the dirt track where the beast will shine: it sports a brawny 449cc engine loaded with titanium valves, with carefully tuned performance to deliver both power and torque right off idle, for hard accelerations and swift cornering.
Adjustable KYB suspensions and a 4-way adjustable ProTaper handlebar provide easy setup for different riders and a multitude of terrain types. Wides-spaced wheels ensure better stability in turns while the aluminium-steel chassis offers better mass centralization and good ground clearance. And with Yamaha's proprietary fuel injection, precise throttling makes the 2011 YFZ450R a razor-sharp racing beast.
