2012 Yamaha 450F. Don't know much about it yet, but do know the guy that had it races and he gets a new one every year. He said that after he raced it, it went back to the factory..?? Anyway don't know much bout the bike, my dad just told me that his pastor is getting the bike and that he is going to bring it by for dad to look at and maybe keep it around for a week. Said that the only thing that wasn't done on it was the transmission. Anyway, don't know a whole lot bout 450F. just have a YZ250. What do ya'll think I should have him look for, do not know if I will be able to take a look at it or not.
