How much would the insurance be for a motorcycle or scooter worth less than 4,000GBP in London?

I'm hoping that it would be a lot less than a 50cc scooter in Dublin worth about 400GBP costing 200GBP for insurance per year.

insurers it seems that the main motor cyclist is bennets although there are other companies i would give bennets a try as they motor cycle racing.
