I was also thinking about some other type of anti-theft device that I haven't seen anywhere to buy, maybe someone else has?
It would be somehting like a wire inside a wire that would trigger the alarm if it would be cut off. Maybe I could connect it to the motorcycles battery so that I don't have to worry about batteries. The main thing would be that it could trigger a horn or something like that but besides that, it could send a wireless signal to a receiver in my pocket so I would know that someone is trying to steal my motorcycle.
It could be made of some kind of relativley thin wire so that it could also act as an "honeypot" for sealers so if they try to steal the bike, maybe they'll first try to cut that wire, and then go to disc lock, big chain or some other kind of anti-theft device.
It would be nice for receiver to have a range of around 500 meters. I'm thinking about this device as a way to leave my bike without worries while staying in a hotel or just leaving it in front of my building.
The receiver could also have a reverse kind of alarming, for example motorcycle could send a "ping" every 5 seconds, and if the recevier doesn't get a signal for 15 seconds it would alarm you. This way if someone finds a way around the wirecutting or turns of the motorcycle battery first, I could still be alarmed that something is wrong.
BTW I like Adventure950 idea about welding a lock to my central stand, I'll see if I can put that instead of disclock for example... Less things to carry in my top case...
