your best chance to catch up is between 120mph to 160's. most 600's will do 160's and 1000 at 170's. quarter miles should be around 10.5 at 140 to high 11's for 600's. The trick is to get the bike rider to wheelie, so he has to drop throttle to bring the bike down. What kind of bike are you planning to race? I wouldn't make bets against any bike if the rear wheel sticks past the rear fender (extended swingarm).
