Paul, It's probably OK, it's a Yamaha thing. DVLA does not recognise dashes "-" on VIN numbers, so substitutes them with a "0". There is some stuff about this on the RD forum. I learnt this when I HPI'd my matching number "4L0" RD350LC before I bought it and got an error when putting the same VIN & engine number in for a matching numbers bike. They remove the "-" from the engine number, but substitute the "-" for the "0" on the frame number. Clear as mud? Anyway, see what I mean below.
