mcman56 Posted October 29, 2009 Report Share Posted October 29, 2009 Would installation of a 1971 swing arm be AHRMA legal on a pre 65 lightweight? I'm planning to install a Bultaco wheel on a C15 but also have the swingarm. It might actually make the swap easier. The rule book mentions frames and engines but says nothing specific about swingarms. I do notice that people modify swingarms and others offer aftermarket arms.
