You keep coming up with ingenious ways of destroying your bike – rear tyres on the front, car tyres on the back?
You can't use a car tire on a motorcycle if you expect to be able to lean the bike and turn. Car tires are not made to lean over.
Don't go over to the dark side. Get a proper 140/80-17 tire for your bike. Why are so insistent on this issue of tires? You cannot put a rear tire on the front. Don't try putting a car tire in the back. Handling is evil. And forget about NOS. Put proper tires on your bike and just ride the dmn thing!!! First link for Avon tire $123.95 and free shipping.
