If you could build a new bike, there will be one hell of a problem in the UK - DVLA, and into europe type approval, and no doubt the US would have another set of regulation. DVLA here seem to be falling into one of 4 camps -
Bike that was UK registered, but has old paperwork and or on system - keep original number or age related plate no problem.
A discrepancy in the above and a maybe a new 17 didgit VIN number supplied, and age related plate.
No paperwork, made from second hand and new parts, vehicle inspection, submit all receipts including proof of duty paid, age related plate or not registered at all - Q plates rare now in these cases.
New bike - SVA depending on the numbers you build - new current registrations issued.
In the UK bikes must ideally come with paperwork - just look at recent UK aution prices, not ebad, but auction houses, the difference in price is staggering.
