Title: B31 with odd frame number
Post by: Crispy Crouton on 17 March, 2017, 07:43:22
Hi. I'm new to the site and hope I'm posting this in the right place!

I have a swinging arm BSA B31. According to the log book the date of first registration was 12/08/1963. However, the frame is stamped with the prefix C15. This doesn't relate to any frame numbering info I have researched, so I'm completely at a loss. It is most definitely a B31 or B33 style frame. Identical to my A10 frame but with the kink in the lower right frame rail. I'm not particularly bothered, more curious really. Thanks for any thoughts on this. Shaun.

There was a posting last year with a very similar sounding B31 frame with a 1963 C15 number. The originator was William. You should be able to find the thread if you access the old forum from the link and put B31 frame in the search field.

Got to be dodgy, a B31 frame with a C15 number. Cannot think of any other way to describe it.

Could have been a victim of the numberplate trade back in the late 1980s early 1990s, before things were tightened up, when there were a number of reports of frames with multiple numbers stamped on them to facilitate reclaim and selling plates. I seem to remember one report of a Norton frame with 9 different numbers most not even Norton, reported in the classic motorcycle press

Thanks Julian

Just my luck if it's a dodgy number. My intention was to make the bike into a special. I suppose the main question is whether or not it is legal despite having a V5C?

Regards
Shaun

If the frame number does not match the V5c, it ain't legal.

Thank you Star Twin. The frame number does match the V5C. So I guess although it's wrong, it's legal?

With the frame and V5c numbers matching it will be legal as far as DVLA are concerned. However, the frame number has clearly been changed at some time in its past and you have to wonder why. There's no need to re-stamp a legitimate frame.
