OnGuard Beast Chain Loop and T Lock 4.6 5 5 5
Withstands Florida rain and heat!! I live in a not so nice neighborhood in Panhandle Florida and this security chain for my bike is absolutely perfect. The sleeve on the heavy duty chain protects the powder coated finish on my wheel and heavy duty construction of the locking mechanism withstands the constant beating it takes from intense heat and UV ray, and heavy downpour we see often in our climate.

Does the job but make sure it will fit. I have had this for a month now and it does the job. my FZ09 is wide open so I thought it would fit easily. The only place this is keeping my bike secure is through the headers. I goofed up one morning and left it on while running, therefore it burned up the rubber to my headers pretty bad. All in all this has worked as a good deterrent and makes me feel safe. October 15, 2014
Aptly Named This chain is a BEAST! Seriously, it weighs around 10 lbs but nobody is going to get your bike. This thing is thick, beefy and mean looking, I love it. Checked on the OnGuard site and saw that this chain is one of the most secure they offer, has a security rating of 97 out of 100. The pole makes it better than other similar chains, you can stick the rod through any opening on your bike, so thieves would have to either cut the chain, that you tied the chain to, or the actual bike frame to get at your bike. You don't have to worry about securing the chain to a wheel (which are easy comparatively to remove) if you don't want to! My only complaint is when I threaded the rod through my bike, the space just over my engine was the only place open on my bike I could put the rod, the heat from the engine sorta melted the actual rod. It's not straight anymore and I do not know how that effects the strength of the metal, so just a heads up to everybody out there, give your engine plenty of room to cool down before you lock up or find a different place in the frame to lock up. For people who think this chain is overkill, think of it this way, you spend 100 dollars to protect a 3,000+ investment. Think about it :) May 6, 2013
Is what it says Pretty cool design - most chains are actually only half the advertised length since you generally loop them around something, but since this chain loops onto itself it's close to the advertised length, which is nice when you can't just park over a chain anchor. Heavy chain, durable parts - only fail point on this I could foresee is the lock on the end of the rod which affixes it to the bike, but after handling the mechanism and moving it around a little it feels pretty rock solid. Didn't want to go ahead and test it with a hammer, but I sleep easy at night with this through my front wheel (and a disk lock on the back chain). April 22, 2013
Easier to cut the bike I have the previous version of this lock. It's been two years of all-out weather - one blizzard and many days of 114 degree blistering sun. This lock abides. The chain has that blue and orange tint of hardened steel. Just looking at it a thief knows it would be easier to cut through the bike rather than the chain. The rod fits nicely through the disks on my front tire. My bike is going nowhere. March 11, 2013
