If you leave the stock fender on you can fit a 120/90. However, I have heard some riders say the 120/90 rubbed the fender bracket at high speeds, so they trimmed the bracket to solve the problem. I have a 120/90 on the front of my "cruiser" America, but I have Honda fender with plenty of room. On my "bruiser" America I have a 150/80-16... Of coarse I had to change the rim and I could never fit a fender.
