OK......
I guess I must be the only one who does this.
I shed my gear, thread a cable lock through the pant legs, jacket arms and helmet strap, and thread through my Heli-bars, all on the seat.
I then cover the bike with my full-size bike cover, you know, out of sight out of mind.
I have even used a personal alarm that is attached to the hooks on the covers bottomm if it is pulled on from either side, it lets out a 130db screem for 2 minutes then shuts off. But I have only used it a couple times, and really didn't seem to need it.
I have never had a problem with this on any bike, from my early on 650's , my Gold Wings and now a couple Connies. A good full-coverage cover and a cable lock does just fine.
I also know, that if they want it that bad, they are not going to mess with the individual crap, they are just going to take the whole bike.
Good luck with what ever you choose.
Ride safe all.
