Selling this aluminum excenter swingarm made by JMC in UK. Had used it on my M/A kettle for 1 season some years ago, but decided then to convert the bike to 100% stock condition. This swingarm is 100% plug&play, nothing more needed to install. Fits with both original exhaust system or aftermarket pipes. Some scratches to be polished out, but guaranteed free of any damage and 100% straight.
