"Okay, here's how it works, how a single bolt can remove the rotor. Its different to the DT magneto which has a full length tapered shaft. The XS 250 has a part threaded section within the rotor body.\n \n\n\n\t\n \n\n\n\tN.B. the normal short bolt with its washer, holds it all in place. \n \n\n\n\t \n \n"
