Have had feedback on covering the above.
Having spoken to underwriters, most mods can be accepted (there are some limits) and underwriters usually deal with this by applying a standard parts clause which limits the cost, where a part needs to be replaced, to the cost of the standard part.
The question is how much does a modification become worth when it has been put on a bike? Minor modifications such as carbon don't seem to make a huge amount of difference to 2nd hand values, sometimes the price is bought down on a comparable standard bike.
Another question - say a set of Marchesini or Marvic wheels were fitted, bike crashes and wheel is buckled - needs replacing - whats an acceptable settlement? Assume new Marchesini = £1600, S/hand £1000, Replacement standard Ducati Wheels = £not sure!
How much extra would you pay to cover modifications (main items, wheels, exhaust and forks) - on the above example:
Replacement as new addl £80
Indemnity (s/hand value) £50
Or contribution to value of standard parts only - no extra cost?
Look forward to hearing from you all! http://www.insuremyducati.co.uk
