How much information do you tell your insurance company

[PieEater]

I very much doubt that un-declared modifications would invalidate third party cover, but what do I know.....nothing probably.

It will be in your policy documents this is a quote from mine;

"If you intend to alter your motorcycle from the manufacturer's standard specification.
Alterations include optional extras and any changes to bodywork; these include but are
not limited to:
- Changes to the bodywork, such as specialist paintwork or body kits.
- Fairing removal/addition, including lowers, huggers and front mudguards.
- The addition of panniers or trunk.
- Changes affecting performance such as changes to the engine management system or
exhaust system.
Please be aware that this is not a full list of all possible changes. All changes made from the
manufacturer’s standard specification must be disclosed.
Failure to notify us of a modification may result in your policy being cancelled or treated as if it never existed, or in your claim being rejected or not fully paid."
