Boards should not be installed in place of a footpeg on a peg mount secured with a single fastener and no anti-rotation mechanism. The board will apply too much force and loosen the mount from the bike. Passenger applications utilizing P/N 7916 requires 1" clearance from bottom of footpeg mount and exhaust. Sits 1" farther out than stock. P/N 4455 is recommended for Passenger use only; bracket design elevates board above existing peg locations about 1-1/4". P/N 7916 can be used for Driver or Passenger. Verify operation of existing shift lever and brake pedal will not be adversely affected by installation.
