There's an "M" Version for motorcycles with a G-Sensor. Looks like the factory is here in Shenzhen.
Maybe need to go have a look and ask about supplemental power. Any good bike thief will sever the battery cables immediately, so need to have some kind of alternative power supply that will last 24 hours. Shouldn't require much more than a good strong cell phone battery.
Edit: Posted at the same time as you LJH... FWIW, I have an alarm system on my V-Strom and it can go about a year without killing the battery.
Cheers!
