Alternator Rotors
13 products
The spinning magnetic rotor that drives the charging system — when it demagnetises or loses output, the battery dies. We stock rotors from MCS, Standard, and Rick's Motorsport Electronics covering Big Twin, Sportster, and Twin Cam, including higher-output options for bikes running heated gear, extra lights, or audio. Check rotor spacing during fitment to keep the air gap correct.
