Theft protection

[Barry]

I use XENA xx14 disc lock because it has build in alarm. Id rather replace the expensive cr2 battery then have the normal alarm drain my bikes battery. Seems pretty solid apart from the pin, which is not made out steel... its been coated to make it look like steel. I dunno if Ive bought a fake one. Hope not.

That's the disc lock I'm planning to buy, there's also an adapter for it so you can attach a chain/cable to the disc lock!
