XENA disc Lock/Alarm? Xenasecurtiyusa.com check it out tell my what you guys think?

 

I've had one for a year. I'm pretty happy with it. Mine was $70 off ebay.
I was thinking about buying a chain but it would suck to carry it around all the time, while xena lock is small and convenient. The model I bought is a bit heavy, but you can buy a more expensive model which is lighter.
The alarm is pretty loud, however I can silent it pretty good by pressing my arm on top of it, so I'm sure a thief could find a way to silence it too. I happened to forget I had it on a few times and it did prevent me from riding away with it.
My best anti-theft investment is my bike itself, I figure: who wants to mess with a 1991 cbr F2 when you have so many brand new bikes around? I don't think I couldsleep safewith a 2007 model as an everyday bike no matter how many chains, alarms and locks I would put on it, especially when I live in Brooklyn.

 

Good point, and thanks for the info
