I have a 2012 Beta 498rr. Will the 5" rear wheel fit my bike? Or will I have to go with the 4.25" rear wheel? An acquaintance of mine told me that he used a 160/60/17 rear tire on the same bike, but wasn't sure if he has a 4.25" or 5" rear wheel. I figured since the tire protrudes out farther than the wheel, the 5" would probably fit, but I'm hoping someone with first hand experience could confirm this.
