Starting with the chassis, the new WR has what Yamaha calls a "YZ250F-inspired" bilateral beam frame, and uses the same KYB SSS air/oil separate 48mm cartridge-type fork and KYB shock as the 2012 YZ250F. It also has a new headlight and all-new, slimmer YZ-style bodywork.
Fuel tank holds 2.1 gallons.
But the big news is that the WR450F is now fuel-injected, so now you can ride to the top of the mountain and back down without having to re-jet the carburetor or make adjustments.
