My worry with stuff like this is, You get an online quote or speak to an advisor, and your bike 'aint in the list and they say:-
"Oh, well we'll put it down as a lamaZukiSaki 750, it's the same really."
YOU sign the agreement that states that "everything to the best of your knowledge is accurate and correct"
You prang or a "smidsy" hits you, and the Insurance Assessor says, "I'm sorry your insurance is invalid because YOU falsified information on the application form, we cannot pay out".
In the UK that also means your Road Tax License is in valid to. The Question is, are you :-
1. Commiting Fraud.
2. Driving without valid insurance.
3. Driving without valid Road Tax
Am I parranoid?
