If you don’t have room to carry a big U-lock or a lock and chain, you can still give yourself an edge over bike thieves with a motorcycle lock. Small and easy to carry, they’re so hard to defeat that most thieves see them, reckon it’s not worth the time and exposure to crack them, and move on to a softer target. Here are the top small and portable motorcycle disc locks you can pack in your pocket, a tank bag, or under your seat.

The Granit Sledg 77's 13mm bolt, lock body, and supporting elements are all made of temper-hardened steel. The Abus X-Plus key cylinder provides the highest protection against picking, and two keys are provided, including one with an LED light. A soft plastic cover makes the lock easy to handle and protects the bike from damage. A memory cable is included to prevent unintentional ride-offs with the lock still in place.

Combining a disc lock and an audible alarm, the Granit Detecto XPlus 8008 uses an automatic brake-disc recognition system that means the alarm won't arm unless it's mounted to the disc. The 3-D motion technology first sounds a warning alarm if the bike is moved, then switches to full 100-decibel volume. Other features include a 16mm steel bolt, an Abus XPlus cylinder for the highest protection against picking, CR2 battery for the alarm, and a carrying case.

Abus Granit Victory XPlus 68 Disc Lock

The Granit Victory's small size makes it perfect for pocket carry. It has a 14mm steel bolt, and the bolt, lock body, and supporting elements of the locking mechanism are all made of a special hardened steel. It features the XPlus cylinder for high resistance to picking, and comes with a memory clip, a protective bag, and two keys, one of which is lighted.

The KryptoLok 10-S DFS is a stapler-style disc lock with a 10mm pin made of hardened, drop-forged steel that resists cutting, sawing, freezing, and chiseling. It comes with a dual-reinforced, high-security, disc-style cylinder, two stainless-steel I-keys, and a pouch with a belt clip for easy transport.

Kryptonite New York Lock M18-WL

The New York disc lock has a 14mm hardened Max-Performance steel shackle that resists bolt cutters and leverage attacks. A high-security disc-style cylinder combines with a double dead bolt locking system for extensive holding power. A sliding dust cover protects and extends the cylinder's life. A pouch and three keys, one of them with a high-intensity bulb and a replaceable battery, are standard.

The X2’s unique shape makes it harder to cut through than the standard stapler-style motorcycle disc lock.Amazon

The X2 has a 14mm double locking hardened steel pin and a pick- and ice-spray-resistant key barrel and body. The double-wing shape makes it harder to cut because it presents two separate surfaces, requiring both to be cut to defeat the lock. It comes with three keys.

Xena XX15 Stainless Steel Disc Alarm

The XX15 features one of the loudest alarms available for a motorcycle disc lock, in a sleek profile.Amazon

The XX15 has a stainless-steel body, a double locking system, an ice-spray-proof body and key barrel, and a 14mm carbide-reinforced locking pin. It includes a 120-decibel alarm with shock and movement sensors and an auto arm/disarm function. A battery and three keys are included.

These are great options to protect your motorcycle from thieves, but they are not foolproof. Attaching a motorcycle lock will deter most, but an experienced crook will get your bike. Invest in comprehensive motorcycle insurance to make sure that your investment will be covered in the case that it does get stolen.
