High Output Alternator Kit, 107mm

High Output Alternator Kit, 107mm

Introducing the EnDuraLast III 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 on BMW R Airhead's from 1977-1995. The EnDuraLast III charging system modernizes the electrical system on your bike at a reasonable price.
