So I ring up my current insurers, Carole Nash, with whom I renewed on 6 September, to tell them I've changed my bike from the S4R to a 996SPS. Thank you for telling us sir and your premium will now go up from £261 to £461, also we need to cancel the original ppolicy and take out a new one and the return premium will be £123 - so that's £138 for 6 weeks cover!!!
I ask them to look further into the market and get back to me.
In the meantime I contact Ducati Insurance
and they quote me £344 for both bikes (SPS and Norton). Since Carole Nash can't improve their terms I've now switched to Ducati Insurance. I have now written to Carole Nash asking for an explanation.
