This is a driveshaft that drives the front wheel on a Rokon motorcycle with an Albion 3 speed transmission. This will also fit Auto bikes that do not have a transmission. This shaft is keyed for the override clutch. It is drilled to fit the original “unlocked” override clutch and it has a second hole to fit the “locked” override clutch that I sell in my store. It will not fit a factory “locked” upgrade override clutch without modifications. It is supplied with 3 new pins and 2 #606 Woodruff keys. I can also supply custom length shafts for Honda conversions.
