You just need the vin number I’m not sure what form it is but the last time I done it for one of my cars I had to trailer the car to the local DVLA office for them, to check it and they issued an age related reg that day as the previous Reg was being used by another car ( the car was 40years old ) but if the Reg is still with the vin number you get it back
All Yamahahas since 1982 have 17 digit VIN numbers
4JH-001785 is the frame serial number, you’ll also find an engine serial number, something like 4JH-001785, stamped directly into the crankcase. The frame and engine serial numbers may or may not match depending on the mo’cycles history.
The 17 digit VIN should be stamped directly into the right side of the headstock and it’ll look something like JYA4JHSOXPA017785
If you can’t find the VIN on the headstock check the right hand frame spar.
Just checked the Honda VIN, seemed like a good idea, made in Italy :ermm:
