Hi, it's the village idiot here... what is a slipper clutch? Is it like on a motorcycle? If you back off the throttle at speed, rather than the rear tire trying to wind up the engine the clutch allows the drivetrain to 'slip' rather than engine brake.

Is this how the slipper clutch works on the Rotax, basically the same concept except with wind resistance in a dive keeping the engine from over-reving? Something like that?
