I am glad you got it sorted insurance should be cancelled as soon as you don't have the vehicle. There were some horror story's going around a while ago about ex owners, who hadn't cancelled the insurance for a vehicle they had sold, being liable for the excess on a crashed vehicle because they were still insuring it.
What gets me is when I re insured the FZ, swintons (previous insurers) said that without me telling them I don't want to renew with them they would have automatically reinsured the bike. Another is the credit searches that the compare sites do - even if you want to pay in one go or at renewal time and you haven't asked for a compare quote again!
