Sounds like a pretty stupid law (structural inspection) as the bike comes with the hump and is part of the design of the bike.
I guess technically everything on the bike would have to be returned to original condition for an inspection. Even changing the air filter to an aftermarket high flow unit would not be allowed.
A friend of mine moved from the UK to France and in order for him to get his motorcycle inspected, he had to change the exhaust as France has a special stamp code requirement for exhaust systems.
No such thing around here, only the basics-lights, horn (switches working), mirror, tires and brakes....the bike doesn't have to run to pass an inspection as long as there's power.
