Protector 13mm hardened boron steel chain (select length below), plus the super-compact RL21 RoundLock. The RoundLock is Sold Secure Motorcycle Gold/Quad & ATV Gold/Bicycle Gold/Motor Scooter Gold approved and the chain is Sold Secure Motorcycle Gold/Bicycle approved. The chain is 2.9kg/metre; the RoundLock padlock is another 0.6kg. The chain is supplied with usually bronze colour sleeving, and the chain itself is finished with either zinc plating or a black finish.
This can make an excellent compromise for portable security for motorcycles.
3 keys supplied.
Keyed-alike available at initial order only (not available retrospectively) when ordering more than one lock together, and only amongst other RL21(A) locks and/or DIB-Series D-Locks. These locks can't be keyed-alike with any of the Squire locks. Please note that the Keyed Alike option must be selected for *all* locks in the set that you wish to be Keyed Alike.
The RoundLock also fits our 16mm chain but is generally not suitable for our 19mm chain unless the optional extra RL21A socket is also purchased and that is used in place of the standard RL21 socket. The RL21A socket is available separately - Please Click for the RL21A Socket product listing. However, please note that some batches of 19mm chain are a little wider such that the RL21A special socket is not required: In those situations, it is better to simply use the standard (non-chamfered) socket that is supplied with the RoundLock. The recommendation, always, is to use the closest-fitting lock arrangement that is possible.
The RoundLock can also be used as a motorcycle disc lock - Check that you have a suitable opening that will take the 21mm diameter shackle in your brake disc or disc carrier. You can then use this with a chain when at home and as a disc lock when out and about. Note that disc locks do not prevent a bike from being lifted into the back of a van, which is a common technique employed by thieves. Adding a chain and physically chaining the bike to something solid can make the difference!

The Protector 13mm chain has the following link dimensions (nominal): 106 x 48mm outside; 80 x 22mm inside. It is constructed from 13mm diameter bar and has a fabric sleeve that is usually bronze in colour (adding about 4mm maximum to the width noted above). If you've got a round hole 52mm diameter, the 13mm chain should slide through OK. It will also fit through a rectangular hole, e.g. 52mm x 35mm, but that requires the links to settle against each other, and more closely as the slot gets narrower, down to the absolute minimum of around 52mm x 30mm high (where it would be quite fiddley to get it to go through).
