So i had the chance to go to Gene Romero's short track series opener. It was in Vegas tonite and they run on a polished concrete floor, to get grip they squeegy on a layer of Pepsi cola Syrop and let it get tacky.
The riders I spoke with said the hookup was working pretty well, they just dont run enough races on it in a season to get the gearing and tire pressure really dialed.
The older (bsa, triumph,TT) bikes dont have room to wind up much but the newer 450 motocross mod bikes were flying.

Anybody else ever seen this concrete/pepsi combo stuff? it was new to me.
