Has anyone had any luck with a 120/90/19 on the rear of a 06' YZ 450? I was looking at Maxxis' Desert IT tire and I would like to go as wide as possible especially for those nasty SoCal hillclimbs. Do the knobbies clear the swing arm? I have always run a 110, I hate to buy/mount the 120 and find out it doesn't fit. I called numerous dealerships and some of them say it will fit and others said it won't, go figure?? Any feedback would be appreciated.
