Well saw a zx10 in action last nite...1/8th mile track...The rider was not familiar with the lights or launch...Bike ran close to a 100mph in 1st gear...Didn't have to swap to 2nd until 50-75 yards before end of track...If it's regeared it's gonna be hell to deal with...The times weren't good low 7's but that's due to the rider...Don't freak around with this bike...If one pulls up on you and knods you better chop it's head and chop it quick...
