Can someone confirm the dates of these numbers please. Vin No- YM2027. Engine No- XM20-2027.
They appear to be matching numbers but not matching years???? Would a YM frame still have girders?
I'll post pictures of it when I've found out a bit more about it

Thanks for that Rick. I see that BSA were not consistent with a new year prefix every year. Bit confusing really. I'll start a new thread about the bike a bit later. Ron
