I recently bought a CB125S from a guy local to me and didnt pay very much for it. I thought it was an S model but it is a 1973 'M' reg and so Im now thinking it isnt a CB125S at all.
Does anyone know how to check what model the frame is and what model the engine is, I can post the first few numbers from the V5 registration document if required, but id like to order a few parts for it and see if I can get it going?
