The WR gained an aluminum frame dropping the weight from 249 to 246 pounds. In addition to the aluminum frame, the 2007 WR450F saw a revised dry-sump engine, with a new balancer, cylinder head, and camshafts with less lift and duration than previous generations and restyled plastics.
. Yamaha also introduced a new model, the YZ450FX, a more Enduro competition oriented version of the off-road 450 utilizing more design elements of the motocross model such as stiffer suspension while maintaining electric start and the 18" rear wheel.
The WR was given the reverse slant, 4-valve, fuel injected motor previously available in the YZ450F
The WR450F largely remained the same, except for modifications to the air box cover as well as a change from silver to black rims.
The WR450F remained similar to the 2016-2017 models, with a large distinction being that the bike was no longer available to register as green sticker in the state of California. 2018 also saw the removal of the kick starter.
