My bikes have been checked by SGS just to make sure the VIN was clear and not been tampered with. They also wanted to check the bike was in standard spec to make sure a age related plate was suitable for the bike. If the bike has been modifed it won't get a age related plate. Every bike must have a NOVA number record on the sytem or the DVLA won't except it. Just about every post says on registering a bike says you need a NOVA number, This has been the case since April 2013. Simple as that, even if no duty was due.. The V5C arrived within a week.
