I do like the idea of a tracker, tried adding one to an insurance quote a couple of years ago and the premium went up.....
Locating anything on the bobber is a pain in the bum to say the least, cant even find a bunged frame rail to slip something into these days, no faring, no cowl and even a non standard seat that makes it impossible to slip something into, it's a real brain bender.
Rest assured the first thing they look for is a tracker when it's in the back of a van or a lockup 2 miles from where it was nicked, but too few places to hide one.
I just go for a garish disk lock, but that dont even stop the little scrotes, seen em smashing a disk with a hammer after scoring it with a grinder (easier than cutting thru) in broad daylight in central London (Luckily it was on camera and i was 2 feet from a red phone, amazing the response you get from picking one of them up then the bollocking for using it for that purpose!)
0-60 in .......oh! wait.... I really don't care anymore (but it's still 1200cc of raw throbbing Trumpet so bugger off Mr.Scooter!)
