Alarms breaks at the worst possible time:
Friday night on the christmas weekend 500 miles from home.
Middle of a road trip, 50 miles each side from civilisation.
Why not a Xena alarm disc lock (XX15)?
It will even warn you when you forget to remove it
Easier to fix if things go wrong (and things always go wrong).
Just don't lose the keys on Friday nigh...
You'll still want to chain your bike to something solid (wall, floor) whenever possible, even when in a garage, with a solid chain and lock.
Most chains and locks on the market are 60 sec jobs to break in, if that.
When chained to a post, you'll want to be sure you can't just pull the post out of the ground.
I friend got his bike stolen at a supermarket, in front of CCTV and security guards with this method.
Cars can be soundproofed so you don't hear the alarm. And tracker proofed.
Bike can be trashed in the car. It doesn't matter if fairings get damaged. It will be sold as parts anyway.
Consider smartwater, datatag, DataDotDNA.
It is always nice to think that thieves can get caught and have enough evidences on them to be prosecuted.
Don't even put a sticker to warn them.
Alarms do break at the worst times. But I just bought the same one and am going to try it. There is anothe thread about this already, and seems like many say it's a great system. The hookups and jackets are all factory matches, so there's no real cutting and slicing, which is where you usually get your problems. That alone should increase reliability. It also has a mind numbing set of features you can customize with various combinations of pushing the buttons switching the ignition, but the instructions are crap. When I install mine, I'll circle back and report
