Thunderbird Commander Insurance problems

Has any one had a problem insuring their Thunderbird Commander?
I bought a Commander in march 2015 and carried the insurance over from my Yam xjr, when I came to insure my Commander in it's own right I found that two different bhp models are listed for my registration, 85bhp and 95bhp, nearly all insurance companies will give me a price for the 85bhp model but only one company will quote for the 95bhp model, I've checked my v5 and converted the kwh and it works out 94.5bhp, I've phoned numerous insurance companies asking why no one lists a price for the 95bhp model and can't get an answer just keep being told they'll ask their underwriters for a price, compare the market only list the Commander as one model (but don't say which) so when I got a price I phoned the company I wanted to insure with and checked they had quoted for the 85bhp model Grrrrrrrrrrr, even Triumph can't/won't help
