Looks sweet and definitely debunks that first photo as a fake, no reverse head here. I think the reverse head would cause issues for tank size on the WR as the YZ has the tank over top of air filter. The YZ has a 6 litre tank :huh: not going to far in the bush on 6 litres.
Now when are Yamaha going to bring out a WR450R like they do with the 250. Thats a bike I would be interested in.
