Disc lock does not work with dirt bikes unless it has a vibration alarm. I was riding out of state and stayed overnight in a hotel. I backed my truck up with bike in the back right up to side of building. A person could not fit between truck and building. I was only 4 spaces from front door. I had cars parked on both sides of me when I went to bed, Woke up next morning to go riding at 7 am and my bike was gone(KTM 450 XCF). I called police and police said the only way they could have gotten that bike out was with a boom truck. Lifting the bike over the roof of my truck. Cars on both sides were too tight to fit a bike between. My truck or cars had not 1 scratch. I think the guy at the front desk had something to do with it. How could he not see it happen 4 spots from front door. Moral of the story if had an lock on the disk bike it would still be gone. If I had a lock with vibration alarm, I might still have that bike.
