I can tell you personally that the Rocket can hang with ANY production bike in a drag race. Maybe it won't win EVERY race, but it'll never get embarrassed. And only bikes like the Hayabusa will straight-up beat it on a quarter-mile. Some folks say that the V-Max will beat the Rocket. What a joke. I've smoked every V-Max that I ran against in the 1/4.
The twisties... well that's a different story. Yes, the Rocket handles surprisingly well for a bike it's size. In fact, it probably handles better than EVERY other cruiser made. But let's face it, it's no sportbike. Still, it handles well enough that a talented rider on the Rocket will still beat a less talented rider on a sportbike. But given riders of equivalent talent, the sportbike will win, of course.
Performance aside, the Rocket looks like it was made to stand next to the Speed Triple, no? ;D
