I use a Zena XX14 which I got half price at the start of the year through a UK Bike paper. It's actually louder than the Meta alarm I have on the boke, fits under the seat in a Digi camera case and looks funky. It's sensitive enough to remind you it's there when you forget and try to ride off - it will go off as you take the bike off the side or centre stand so there is no chance of fecking your brake discs which = £££££'s as a mate did about 13 yrs ago on his DR350S.What type of lock do you use for your bike. I live in a apartment complex and don't have the opinion of parking it inside.. What in your opinion is better, U-lock, disc lock, cable, chain etc.... any advise would be helpful.. Thanks.
