HELP, DATE OF ORIGINAL BUILD

HELP....
I've just rebuilt a st70 and was wondering what's the year of manufacture?

Frame number st70 149587
Engine number st70e 148062

Any help much appreciated.
Regards Dean

Hi with the frame and engine number it will be possible to apply for the bikes logbook, with that you will get it original registration number, it does have an element of risk, if the bike is noted as stolen for example you could end up returning it to its registered keeper

Also not a good idea to put the whole frame number on here, could be copied
