Agree with all the comments about being easy picking for the odd copper that decides he does not like bikes
after all we are public enemy No1.
As for the insurance, come clean and tell them about all mod's etc. Told mine about all the different body work, huggers, decals etc etc and they came back, in writing, to say that in the case of a claim they will treat the bike as standard and will either repair or pay out as a standard bike. No additional premium or owt
