Ace says... [QUOTE] OTOH WTF are you doing to get through a BT45 in that time on a 600 commuter? Burnouts at every traffic light, perhaps? I used to get that much out of a BT57 or 020 on the Sprint ST I had, even when doing commuting miles, and it's considerably more powerful on a considerably more grippy tyre, which defies logic.[/QUOTE] I used to destroy a BT45 on the back of the 350LC in about 3500 miles maximum. They grip well though.
