I looked into Datatool's TrakKING before I bought my '09. For me, it made no difference to the insurance premium, but with any preventative/insurance measure (outwith the legal requirement, of course), if the comfort outweighs the associated costs, then it's worth it.
Interesting.. Will have a look at that. PB did an article on something similar. Parking the bike in central London every day I'd like to know where it is!
