That's a huge chain hence the use for a motorcycle. I have a friend who had a Harley Davidson that he used a chain similar to that that he locked his bike up with then the chain was locked to a real thick hardened steel shackle bolted into the cement garage floor, then of course the garage was locked. Somebody(s) opened the electric garage door by driving wedge right in the center of the garage door at the top, then reached in with some sort of perhaps a coat hanger and grabbed the emergency release cord to the garage door and opened the door. Then they cut the chain with a cordless angle grinder. how long they spent in the garage doing that we don't know, but the bike was stolen and was never recovered. Of course his insurance covered it but it was a hassle never the less. So he now installed a burglar alarm on the garage and house, and he cut the plastic handle off the cord that releases the garage door so they can't grab onto the cord. I did the same thing to my garage door too.
