How much is your road insurance? is if F&T or fully comp?
You would need to keep the bike MOT'd and taxed presumably for that to be valid, but that might be cheaper than track insurance? Basically if your road insurance is <£500 then keep it road insured TPF&T and daylight MOT it.
There are insurance places that will insure your race/trackbike and all your gear against theft. I can't remember the name of the company that was recommended to me, but ask on here
www.motoforum.net as that is where I got the info.
Anyway, when I phoned up, I found the price pretty steep and they wanted a tracker fitted ...
To be honest that is probably your best bet anyway ... i.e. get a tracker in it ... as soon as it goes missing, then call in and it can be tracked ...
Oh and finally I figured that bearing in mind the cost of the theft insurance, coupled with the fact that when in use I have to accept I could throw it down the track - and write it off in an instant anyway, that I bowed down from coughing up to insure against theft ...
Anyway, that was my logic, but you will want to get a quote and make your own decision ... so if no one comes up with some names to try here then put a post up on motoforum
