WR450F

WR450F - 450-Class Torque, 250-Class Agility

The latest WR450F from Yamaha comes with a wide range of advanced engine and chassis technology that’s designed to deliver winning performance on the track and all-round versatility on the trail. At the heart of this remarkably capable enduro bike is a gutsy and reliable 450cc 5-valve engine which is renowned for its strong and useable power. And for 2012 we’ve equipped this legendary powerplant with an advanced fuel injection system for even more stable and responsive performance. The chassis also gets a serious upgrade, and the latest WR450F now runs with a compact 250-class bilateral beam frame for quicker turning and enhanced agility.
