Segment: ATV/Quad
Production years: 2012, 2013
The 2012 Yamaha YFZ450R is an ATV designed to race the motocross and dirt tracks, loaded with all the high-performance specs one might expect form such a machine. 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.
The 2012 YFZ450R 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. A counterbalancing shaft reduces vibrations and the low-to-mid rpm range tuning of the power plant ensures you get tremendous thrust right off idle. And with Yamaha's proprietary fuel injection, precise throttling makes the 2011 YFZ450R a razor-sharp racing beast.
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 to easily pass over obstacles and keep a good balance during jumps/
