Replaces the under performing Bosch charging system with a 105mm outside diameter stator (timing cover side) and stator frame side outside diameter is 105mm on BMW R Airhead's Slash /5 ONLY. The EnDuraLast III charging system will reach charging voltage sooner than any other BOSCH style charging system we offer. Ideal for the urban low RPM rider.
