Alternator
High output.
Alternator Charging System with heavy duty stator and rotor with increased electrical output.
The EnDuraLast III uses the same Bosch design with upgraded diode board, regulator, stator, and rotor.
Replaces the under performing Bosch charging system with a 107mm outside diameter stator (timing cover side) and stator frame side outside diameter is 107.5mm on BMW R Airhead's from 1976-1995.
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. Technical specifications according to the manufacturer.
