Welcome to the forum from New Jersey.
No chopper activity in SA. Well you can change that. I know there are go fast people in SA as a Flathead record was just set by a Guy from SA at the Bonneville Salt Flats. His son talked him into going and set the record on his (the son's) bike.
index Paul Freibus owns the shop and the bike and his father Henry set a record - one of them anyhow. Interesting story, you may want to check the link. Hope I remebered the details correctly.
