How long a chain do you need to secure your bike. I see locks that are 85cm and once you wrap it around something on the bike i'm guessing there's really not much left to secure it to something else. Looking for a chain to use when parking the bike so I guess you don't want a chain that is too long and heavy. Will be using the chain to secure it to a pole in the garage too. Currently have my eye on this KRYPTONITE New York Fahgettaboudit Chain 1410 - 14mm x 100cm. I have a 92 honda cbr250RR if that helps.
