The rotor is the rotating magnet component of the alternator, spinning inside the stator to generate the bike's charging current. Lucas made the alternator systems used on these bikes, so a Lucas-branded rotor fits with what we'd expect to find in that assembly.
Our catalog record on this one is thin beyond the single listing, so if you're matching this to what's currently on your bike, give us a call and we'll confirm fitment before you order.
