Hi all, i have read all the similar threads about this but still can't decide so maybe you can help me out. I race Enduros and Hare scrambles and i also want to try MX.I'm 6.7, 246 pounds and i'm riding a WR450f 04 since 2004. I have done all the free mods and the bike is perfect, lot of power,very aggresive and fast. The only ''popular'' problem is weight. Every time i fall it's really difficult to lift the bike up. After all those years i decided to buy a new bike with aluminium frame of course. I can't decide which bike to buy, i badly want to buy a YZ450 because i know it's really light and cheaper than the WR but 1)Am i gonna be satisfied? 2)Will the YZ450 fit me? 3)Is it difficult to get used to it compared with the WR? 4)Can i ride the YZ in trails or i have to do some mods first?
