Foot shift to jockey shift conversion kit. A radical custom set-up to fit bikes with 52-E79 Big Twin 4-speed transmissions with the stock early 52-E79 style ratchet top only. This suicide clutch set-up enables you to install the shift lever directly to the ratchet top on the transmission; placing the shift lever below the left side of your seat. The ''suicide'' clutch is a controlled by the left foot and functions just like the clutch pedal in a car; without any friction-hold system like used on the foot clutches of stock tank-shift models.
