Hi Mo,
I tried the motorcycle NCB but they weren't interested the premium started off at £651.00 but I managed to get down because I earn a NCB as a named driver on the wife's policy.
The problem is I've had a company car for the last 12 years with the bikes, I couldn't even use the NCB from the Company Car because I reversed that into a taxi last year
The cars more than worth it so I'm reasonably happy to pay.
