High security motorcycle disc lock. 10 year guarantee from Squire. Sold Secure Motorcycle Gold.

Note: Most motorcycle thefts involve the bike being lifted into the back of a van. A disc lock on its own, like an alarm, is unlikely to prevent such an attack. You can use a disc lock to also lock a chain around street furniture etc, for much better security. A disc lock on its own is only a small deterrent.

Available Again! Untouchable super-compact padlock. Sold Secure Motorcycle Gold, Classe SRA approved and NF certified. The German-manufactured innovative Untouchable lock is lighter and a lot more compact than the Squire SS65CS whilst offering similar security at a much cheaper price. Note that this is a 2-part lock where the top section comes out completely and is then re-inserted sideways through the chain and into the female lock receiver. It may be harder to use than the SS65CS as a result (although you typically need 2 hands to fit that lock to a chain as well). 21mm diameter shackle. 3 keys supplied. Keyed-alike not available. 0.55kg

Very compact, Sold Secure Motorcycle Gold approved and suitable for Protector 16mm and Protector 13mm chains at a great price!
