bikes to steer in the opposite direction of the turn (negative steering angle) to maintain control in response to significant rear wheel slippage. Motorcycle speedway racing takes place on an oval track with a loose surface of dirt, cinders or shale. Riders slide their machines sideways, powersliding or broadsiding into the turns, using an extreme form of this type of countersteering that is maintained throughout the turn. This also works, without power, for bicycles on loose or slippery surfaces, although it is an advanced technique. The term is also used in the discussion of the automobile driving technique called drifting.
