[quote name=My question: on what ground that you call me "wrong"? Like I said a bike with a 300 wide tire that is currently avalible will be slower than the same bike with a more traditional size. 1)300 tires are not currently made in sticky or soft copounds= slower off the line,probably spinning! 2)300 wide tires have more weight and drag= lower top speed! 3)Bikes don't turn as well or as easily with wide tires! 4)Most 300 tire kits use a prop shaft or jack shaft set up.Those are soooo cool! 5)posers love them!!!!!!!!!
