anyone have issues with tire rubbing swingarm? the bike had a nearly new pirelli 130-80-16 mc 64p on which promptly got destroyed after about 100 miles. i dont what size you can go on this, apparantly not the size mentioned. the only other thing i can think is that im too heavy at 250lbs and it distorts the tire? thats probably not the case. so im gonna need to buy a tire, can anyone suggest a size to use?
