Remember those old BSA V-Twins? Me neither. Well, here's one to think about, it's a 1963 BSA A10 frame with an engine created by a P.Thompson in 1991-1992. It uses the BSA A10 gearbox, with cylinders and cylinder heads from a B50 along with a B50 carburetor. Total displacement is 1100cc.
The seller of this bike, over in Germany, says there were only 5 built, of which this is number 3. He also says the bike is complete and runs fine. Since it's made from BSA engine pieces, you wonder why BSA didn't do something like this themselves. Of course, we can ask all sorts of questions of why BSA didn't do one thing or another, but it's nice to know someone went to the trouble to create something like this later on.
A couple of years ago we showed you another V-Twin, the BSA B66 built by Doug Fraser. I guess there is a sub culture of builders that look at BSAs as fertile ground for this sort of thing, though you have to have some serious machining skills to carry it off.
The link for this came up in a comment by Barry a few days ago and it looked like an interesting build. Thanks, Barry!
