I have a friend that can get Banshee VS 5100s bike alarms, I had one on my gixxer worked really well. It also saved "shortys" R6 last year.
the alarm has a shock sensor (fully adjustable , tilt switch, four way flasher, with an led. Remote controled. Also wires to your ignition.
They are Loud!
$165 aparently retail for almost 300?
Let me know if anyone is interested, I'm not sure how many are available.
