The 2011 Yamaha YFZ450R SE is the ultimate ATV motocross racing machine designed to deliver premium performance in the most demanding situations. Since handling is one of the key ingredients of winning a race, the 2011 YFZ450R SE comes with a weldless aluminium frame with a tensile steel bottom part for a lowered center of gravity and more stability.
The titanium valve 449cc engine has been tuned to deliver low-to-midrange torque for powerful acceleration during slow corners and plenty of torque to tackle obstacles. With piggyback reservoir adjustable suspensions, the 2011 YFZ450R SE can be rapidly set up for various riders and a multitude of terrain types, delivering great grip and excellent balance.
With a wide wheel spacing and generous wheel travel, this ATV also comes with good ground clearance, making fun for trail riding as well. And in case you crash, the bodywork parts can be easily swapped without tools, and without too much hassle.
