I got a Zena lock. It works pretty good for a lock. It cost me tooooo much money,bought it at the dealer. It does irritate the neighbors and my wife. The wind or vibration does seem to set it off to often. I also got another lock that actually bolts in place of the left front caliper.This moves the brake caliper down a bit and you have to run a longer brake line. It has a spring loaded pin that you put into the lock,I like it better than the Zena. No noise with the second lock,much much more money,but these bikes aren't cheap are they. Oh yes and you need to remind yourself one way or another that you locked the front wheel. I wish Victory would install a fork lock on the X-bikes. I know that a thief can break them easy, but it is somewhat of a detour-ant.
