I have many bikes that used these size tires and any of these are great to very good: Pirellin Sport Demons, Shinko 230, Bridgestone Battleaxe 45 or S-11.
These I will never buy ever again!: Continental, Dunlop, Kenda, IRC (These brands are ONLY good for dirt bike tires as they tend to be hard as rock)
www.motorcyclesuperstore is the best place to buy tires. Incredibly FAST shipping and FREE if you buy over a certain price. (usually the price of one tire or tire with tube.
