Rebuilt alternator/charging style rotors for street bikes. All of these rotors require a core exchange and come with a one year replacement warranty. We cannot repair and do not sell permanent magnet rotors. Field excited charging systems, such as Honda CB750/900s are notorious for charging problems. Click here for testing information on these systems to find the part you need. We also offer rotor pullers to assist in taking your old rotor off. Please give us a call if you would like to purchase a rotor puller.
