Segment: ATV/Quad
Production years: 2009, 2010
The perfect blend of power for the toughest terrain and situations and the precise handling MX machinery needed to get the rider past the finish line, the 2009 Yamaha YFZ450R is a spectacular ATV. It sports the incredibly sturdy, light hybrid chassis rolling on adjustable long-travel suspension. The wide-track architecture offers great stability even in fast corners, while the sporty 449cc engine can produce enough torque for strong accelerations in pretty much any situation.
The new wheels have rolled in inner lips, and this decreases weight while increasing strength. The easy and precise throttle lever requires little effort, so riding it all day long will be less fatiguing and more rewarding. And with a 5-speed manual gearbox, riders will be able to squeeze the last drop of power from this evil MX machine. And still, the 2009 Yamaha YFZ450R can be also used as a fun-focused ATV for casual trail riding.
