The 500 definitely has more passing power. For those who say the 500 runs out of breath at 80-85, something's wrong with either your bike or your riding style. My 500 will get right on up to 100 in a snap. I suspect some who say that don't know to downshift into the rev range before passing. The 300 is the same way. You have to downshift into the rev range for passing power, but the 500 definitely has more torque there. You just need to know how to get on it.
, try taking your ninja out onto the freeway and get up to 80...then downshift from 6th to 5th and throttle on hard at the same time. Do that and then tell us how you feel about its passing ability. The ninja 300 can do it.
