My friend had a funny argument with the WoF guy (similar to your MOT) here in NZ about this. After a bit of debate he just took the seat off. The guy wasn't legally allowed to fail the test because there was no longer a seat fitted. Might be worth keeping that trick up your sleeve...I think that might be the same one, thanks though Noggie, I heard something about failing your MOT if you have no pillion foot pegs but a seat for one? not that i need to worry about MOT just yet.
