Description
This is the correct fit rotor for all Moto Guzzi's with a Bosch charging system.
Buyer Beware: There are two Bosch alternator rotors that look the same but the one for the BMW is 1/2mm smaller and allows too much air gap and will not charge properly when used on the Moto Guzzi.
Correct measurement for the Moto Guzzi rotor is 73.5mm.
BMW measures 73mm. 1/2mm = .020 excessive air gap.
We only sell the OEM rotor for the Moto Guzzi.
