It's a real problem that many insurers simply wont tackle. Carol Nash must have changed their policy recently because when I asked them if they would insure my bike with termi's they simply asked "if where they on the bike from new" my answer was "no" like most ducati owners. As such the bike was no longer standard and they would not be able to help me... Silly me for mentioning it.
I would say that most ducatis with 'termi' pipes are doing so due to non discloseure.
Unless of course you have a bike that has them fitted as standard, I think that is the Foggy rep only?
Thanks for all the advice guys. I rang Premium Choice and they said Equity Red Star will not insure with termis. Still unsure what to do but thanks again. If I was due to renew then I could phone around but not due until November.
