I've just sent in my application for my WB30. It's not finished yet but I've temporarily hung some more major components on for pictures to go with my application. I've done this loads of times over the last 30 odd years.
The latest procedure is :-
You need a dating letter to start with. Owners club or VMCC (In my case the Military Vehicle Trust)
Download DVLA form V55/5 and follow the instructions in leaflet V355/5
A lot of it doesn't apply to a "Historic" motorcycle so leave those questions blank.
Include pictures of the bike and clear pictures of the frame and engine numbers ......Include a cheque for £55 made out to DVLA.
No need for an MOT or insurance or a NOVA certificate if it hasn't been imported.
