Note that the XN15 sample that Xena sent us is actually too large for the Ducati GT1000 brake disk rotor shown in these photos. The XN collection also includes the big XN18, which is 113 mm (4.5″) long and also features an 18mm diameter four-pin locking system and an LED light to let you know it’s active. The Xena Disc Lock comes in four different sizes, from the 80 mm long XN10 (3.25″) and XN14 to the 102 mm long XN15 (4.0″) shown here. It has to be the heftiest disk lock I’ve ever tried. So I’m impressed by the Xena “Disc Lock Alarm”. This isn’t the place to save a few bucks. Now I’ve seen some pretty cheap-looking disk locks for sale and more than a few that cost only a few bucks and will probably break as soon as the wheel turned one rotation. It would be nice if they installed some ground anchors to use with the chain, or if they provided motorcyclists with the same type of enclosed and locking bicycle huts they have for bicycles, but I’m not holding my breath. And if I think I might not be back until after dark, I’ll throw a chain around the wheel also. I always use a disk lock when I park, because it just doesn’t make sense to leave the motorcycle behind with only the fork lock to protect it. I occasionally ride down to the nearest Metro stop and park in the little fenced-in area they have set aside for scooters and motorcycles before I take the train the rest of the way into downtown D.C. The situation I can definitely relate to is parking a motorcycle at the Washington D.C. This will surely prevent the vast majority of “casual” thievery, no? Second, a layering strategy should be employed, combining, say, an alarm system with a disk lock or a chain or other anti-theft device. But while our mates are hashing it out in the pub, there are at least two things that sensible motorcyclists can do to protect their pride and joy.įirst, to help prevent a “crime of opportunity”, an anti-theft device should be used, and just about any anti-theft device is better than none. Of course, both of those arguments could be debated ad infinitum without settlement. So it could very well be that a motorcycle protected with one or more anti-theft devices might get a pass from said thief. The counter argument says the thief wants to act as quietly and as quickly as possible, attracting little notice. That’s determination…but surely determination of that sort must be pretty rare? This may or may not be true - but what, exactly, does the word “determined” mean?Ī motorcycle could have disk locks on every brake rotor, chains holding it to floor anchors and an alarm system on the bike and the locked door of the garage.īut still, someone with the time, energy and motivation, could steal the bike anyway. Some will say that disk locks, Grip Locks ( wBW review), alarms and even monster chains like the OnGuard “Beast” we reviewed won’t prevent a determined and experienced thief from stealing a motorcycle. Shackle may not be long enough to fit around some brake discs

It serves as a good deterrent for a would-be thief and a warning for the owner if the lock is accidentally left in place before riding off.Īppears to be high quality and more robust than other disc locks of its type. High-quality, hefty disk lock includes a shrieking 110 dB alarm.
