You can do things like that on those SuperMoto bikes that you can't do on a roadracer. It's almost the same as riding a dirt bike. I have spun a dirt bike around and around in circles (in the dirt) while practically laying on it's side. I used to race MX back in the late '70s. To many injuries, the boss told me to either give it up or get fired. But pavement is a whole nother thing. I tried roadracing once on a rented bike, always came in dead last, was told I wasn't leaning over far enough. Every single one of the other racers (this was a track day at the Bondurant Driving School track) talked about crashing multiple times, like it was no big deal. All the employees at the local Cycle Gear store ride sport bikes, and they have all been down. Now, I admit I have ground off the peg feelers on my Ninja 500, but have never come close to crashing, and never will. I simply won't push it that far. Again I see a HUGE difference in going down on a dirt bike, which is to me part of the deal, and crashing a street bike, which is a flat out accident, and is NOT part of the deal.
well to be honest riding a crotch rocket like that its a work out and a half your fighting the force of the bike to want to stand up, your fighting the extreme bucking of the wind
its alot of skill to do something like that tho a mouse turd on the asphalt could spell disaster so either way going that fast and being able to control it.
someone once told me now i dont know if this is true on a crotch rocket when your going a top speed you only got the thickness of a dime making contact with the road if thats even remotly true a mouse turd would do the disaster part easily enuf
