Ok just got back. Rode both the WR450 was fine, 250 was ass, had to wind it out way more. I can touch with both feet to the ground "tippy toes" so that part was fine too. I could pick up both bikes. This one was rejetted and titanium exhaust which I will put back to stock for now. I was told by the 250 guy in Canada there is no throttle stop or grey wire that it was only a US thing.... In the end I think because of the Italian factor I was fine, hahaha. I just have to be more careful with it, and like buddy said just use my head. But man the wr450 is a nice ****ing bike for sure!!! so, did you buy the 450? I think the grey wire and throttle stop are on canadian bikes as well. any canadians know about this?
