Can you tell what the bike started life as from the frame/engine number. I have just bought (a month ago) a 748 which to me is the best I have ever been on. The bike was sold to me as a BP it looks like an S but it does come with all the original parts. Wheels seat unit etc to put it back to a BP. I bought it as a BP and so am not to concerned either way just it seems to say 748S in a lot of places
