@ #25: The Himalayan has predictable power, a plus for learning sideways travel. Breakaway traction is determined by track surface & tire selection. Even modest HP levels can break the rear tire loose with suitable tires on a suitable track surface. No doubt the Slideschool folks have dialed the track surface & tires in to suit their training program parameters. In the wayback after hours we used to flat track around our old shops linoleum floor on the Italjet folding porta-bikes we were selling. WFO sideways on
maybe 3 HP, steering with the throttle, knee sliding on linoleum, setting up on the 30' straightaway for the tight sweeper around the bosses desk...
Fun is where you find it.
Here's some real guys with real HP at real speeds:
