Just wondering. Did any other British bike manufacturer forge their own crankshafts as BSA did? I can't think of another.
Before I get back to work properly next week, I decided to deal with a slightly dismissive inquiry from a young (mid 40s) acquaintance. He wanted to know why the AA used old sidevalve BSAs for their sidecar patrols, when there were more modern bikes available, for example the Nortons used by the RAC patrols!
I've explained that cost would have been a big consideration, both initial outlay and cost of ownership for the entire service life. The low-stress M21 was scheduled by AA for major overhaul at 50k miles and expected to cover 100k miles before replacement.
He wasn't convinced. Does anyone have any references to AA operating guidelines/specifications, please?
