You are going to go with a notched out swingarm?!?!?!With my last mod for the winter, I am taking the plunge and modifying the rear to put a 300MM tire on. Found a local fabricator that's widening my rim to 10 inches and notching out my swingarm to make room for MAX tire. I saw that RAW DESIGNS does it in their kits (swingarm) so now I dropped off my parts and wait for the fab work. When it's all said and done it should be just under a grand including the tire.
oh, you also have to modify the metal fender to make it work.
