Racing motorcycle seat with rollers and toothed belt

摘要

A seat which may be for a racing motorcycle has a frame 1 having a plurality of tapered rollers 3 mounted thereon. A pair of toothed flat belts 2 engage with 3 of said rollers. A pair of further rollers are located one on either side of the three centre rollers and are connected via geared sprockets 4. The friction, rotation and recoil of said rollers may be adjusted via dials 5. A motorbike rider shifts his weight across the seat and hence leans from one side to the other to change direction. Movement across the longitudinal axis of the motorbike causes the rider to move the belt with respect to the rollers. The rider uses their thigh and buttock muscles to control movement.
