BSA B40 identification HELP please

Featured Replies

I have just purchased what I've been told is a 1968 BSA B40 Otter Military with engine number B40 GB 1123 can anyone help with confirming the age of the bike? I'm also looking for a manual and want to make sure i purchase the correct one

Many thanks in advance

The Otter frame is one thing,made later than the engine which was originally fitted into a BSA frame. Not sure if you can date an Otter frame,has it got any numbers on it ?  The engine can be dated from the factory dispatch records, the BSA owners club can help with that.

Many thanks Hughie that was great to get that info and  see the pictures of the bike. Can you possibly confirm the age i was told it was a 68 and when i look up the engine number it is a little confusing to me and think it might be 67

screenshot below if for year 67 i don't seem to bee anything in 68 for B40GB

Any info would be very much appreciated

Cheers, Austin

PS I'm new to these old bikes

Thank you

i haven't seen any numbers on the frame but to be honest i haven't had a real good look and if there were they may have been painted over at some point

Cheers, Austin
