Oxford Bumper Cable Lock 4.3 5 3 3
Does the job.. Small enough to fit under my seat but sturdy enough to keep my helmet secured.. Best feature is the protective coating that keeps the lock from scratching my paint.. August 17, 2015
Good, compact lock...but with a big caveat This lock is a good size and length and comes with two keys. It is easy to store in a smallish space on the bike or in a pocket. It has a nice coating that won't scratch my bikes or my helmets. The main thing to be aware of is that the end will not fit through all brands of helmet D-rings! I have multiple helmets and this lock works fine with my Bell and Fulmer helmets but not with my AGV and Shoei helmets. With the AGV and Shoei's, if I want to use this lock I have to use another helmet lock (like the carabiner type for example) that will fit through the D-rings and then put this lock through that helmet lock. So if it fits through your particular D-rings, it rocks! If not, not so much. April 13, 2015
nice little lock This is a nice little lock to secure your stuff in relativity safe areas. It is small, lightweight and easy to keep with you. My bike does not have a helmet lock so I use this to lock it to my handlebars. March 9, 2015

KM Y: It goes through one of the bigger D ring of the HJC helmet. The small end diameter is about 9/16th inch. I think locking the D ring defeats the purpose of the helmet cable lock. May 28, 2015
