BSA Crankcase complete with fixed fittings
BSA A70 crankcase assembly, complete with its fixed fittings, from the same parts family as the A65 Lightning.
This is the crankcase assembly for the BSA A70 engine, listed in the catalog as complete with its fixed fittings. The A70 figure notes that apart from a short list of differences, the model shares its parts with the A65 Lightning, so this casting sits in that same family of BSA unit twins.

The catalog entry we have is a single line with no further breakdown of what "fixed fittings" includes, so we can't tell you from our records exactly which studs, plugs, or bushes come attached versus fitted separately. If you're matching this against a numbers-off engine, bring your old cases or numbers so we can confirm you're getting the right casting.
This is a BSA part, not a Triumph part — don't confuse it with any Triumph crankcase numbers even if the shapes look similar.
We've never carried this one. Tell us what you're after and we'll go looking — you'll get a price and photos before you commit to anything.
