I'm looking to replace the front tire on my YZ400F. I've got a race at Glen Helen in two weeks so I'm trying to pick the best tire for there. I'm running a 739F on the front and a one of the new 4 ply 739FA's on the back now. I'm happy with the back but the front has the nasty habit on letting go without warning, partly I'm sure because of wear. I'm wondering if anybody's tried the 739"FA"? It's rumored to be a lot better front tire than the 739"F".
Your thoughts?
