This BDL 2″ belt drive is of a ‘wide-open’ design. Features a 2-piece motor plate for that nice open look between the engine and transmission as found in many Shovelhead type open drives. Comes with a 52-69 pulley drive ratio and a 6-bolt diapragm clutch configuration with a slightly different, more true, feel. Note: See 518533 for the replacement 132t. 2″ wide 8mm belt.
