Legal experts please confirm if I am wrong but............
Tickets are between the driver / rider and the MOT / police with the information available to the insurers.
Claims are between the owner and the insurer and the police only care if there was dirty riding involved.
Someone in the insurance business told me that a collision related surcharge can only be applied to one vehicle, not the owners whole fleet. Obviously the insurer will, if they can, pick the most expensive rate to double up on.
I suspect the tickets are different in that they do apply to the whole fleet.
Claims and tickets have different expiry dates regarding how they affect rates but there can be a tricky question. If the insurer asks if you ever had a claim and you say "No" because it was a dozen years ago you have lied. An better answer would be "Nothing relevant" but I don't know if the insurers have a tick box for honest answers.
Re write offs:
When I wrote off a mini van ages ago I was given the option of keeping the van and taking some fix up money.
I'm not sure how this works but if a vehicle is fixed under an insurance claim it would show on a car fax report but if you fix it yourself it wouldn't.
Also the reason the insurers write off is that a shop won't spend days searching the net for odd parts while having their shop jammed with bikes waiting for deals on parts. If you have a safe work space you have the option of taking your time to save your money. Bikes are relatively easy to repair compared to cars.
Keep the above in mind if you let anyone use your vehicle, even for a test ride. If the test pilot, unfamiliar with the bike and pushing the limits, has an at fault the owner gets the rate increase.
Remember when life was simple?
