Duncan -- Currently insured via Bennetts , previously via Motorcycle Direct and have always declared all the mods , including the wheels (off a '98 R1100S) , all with no problem -- except the wheels in my second year with Bennetts .
Initially they refused me cover ; this after having insured me the previous year ! After some discussion - including me asking them to put the reason for refusal in writing , they agreed to continue offerring cover - I used the , "you've been insuring me for the past year without any problem" together with coolcan's line of , "the wheels allow me to fit road tyres which are much safer therefore you should be lowering the premium offerred !" These arguements worked - as does the conversion !!!
All the best , James
