10 Best Motorcycle Locks in 2026

Kryptonite gives this chain lock a 10 out of 10 security rating, and the 15mm six-sided hardened manganese steel links are why. The chain resists cutting, sawing, and leverage attacks, so it’s built for the highest-risk urban environments where you’d leave a motorcycle or e-bike locked up. At five feet long, the chain works with large bike racks, poles, and street furniture, letting you wrap it around different objects in several configurations.

The trade-off is plain: 14.7 pounds is a lot to lug around in a backpack or strap to a saddlebag every day. If you ride short errands and want something far lighter, a disc lock like the URBAN UR14S at 1.6 pounds is an alternative. But for a motorcycle that sits outside in a high-risk urban area, the extra heft is part of what makes this chain a serious deterrent. The reinforced hardened steel lock head and disc-style cylinder are engineered to resist picking, drilling, and tampering attempts.

A 14mm double-locking shaft that locks at both ends doubles the resistance against prying and cutting, making this disc lock a serious deterrent for anyone after your bike. The 120dB alarm can be switched on or off by pressing the lock cylinder, so you decide when the siren is active. That flexibility, paired with the SRA and Sold Secure Gold certifications, means you get verified security without being locked into a constant alarm. It suits riders who park in moderate-risk areas and want an audible warning that keeps thieves from even touching the bike.

The trade-off is that 1.6 pounds is heavier than many compact disc locks, so it adds noticeable bulk in a jacket pocket or under a seat. Compared to the ABUS Granit Detecto X-Plus 8077, which weighs 1.9 pounds and also offers an alarm, the URBAN is lighter but still not a featherweight. For a rider who wants certified protection with a customizable alarm, this is a well-rounded pick.

The 12mm hardened steel locking pin and advanced material technology let this disc lock withstand sustained angle grinder attacks, a level of protection that matters most when you park in high-risk areas. It suits riders who want maximum physical security in a compact package, backed by high-level Sold Secure and ART certifications that confirm its toughness.

Weight is the main trade-off: at 2.5 pounds it is noticeably heavier than an alarm disc lock such as the URBAN UR14S, and it offers no audible deterrent. For someone who prioritizes cut resistance over electronics, this is a focused, capable choice.

This lock earned the highest Sold Secure Diamond rating, meaning it resisted bolt cutters, hydraulic jacks, and drills in official tests. The 13 mm hardened manganese-chromium steel chain and 16 mm shackle are built to survive attacks that would defeat many other locks. So if you park a high-value motorcycle or e-bike in a high-risk area, this is the level of protection you want. The 5-foot length gives you enough reach to wrap around a lamppost, tree, or wide anchor, and the multi-disc cylinder adds real pick and drill resistance.

At 13.2 pounds, this chain lock is meant to stay at a fixed parking spot rather than travel in a backpack or on a bicycle frame. The Kryptonite New York Legend 1515 is a bit heavier at 14.7 pounds, but both are too heavy for daily carry on a bike. For portable security, a disc lock such as the URBAN UR14S makes more sense, but for a motorcycle or scooter parked in the same place every day, this chain provides real deterrence.

The ABUS Granit Detecto X-Plus 8077 uses a 13.5 mm hardened steel locking bolt and an XPlus cylinder that offers very high protection against tampering attempts such as picking. Movement on the motorcycle triggers an intelligent pre-alarm, and if the disturbance continues, a 100 dB alarm sounds for 15 seconds. That sequence gives riders a chance to scare off a thief before they can get to work on the lock itself. The brake disc detection system also lets you transport the bike while the lock is closed without setting off the alarm.

The alarm only sounds for 15 seconds, which is enough to draw attention but not a sustained deterrent compared to locks with longer or repeating alarms. It also weighs 1.9 pounds, so it is light enough for a jacket pocket, but as a disc lock it only secures the brake rotor, not the frame or wheel to a post. If you need to lock your motorcycle to a lamp post or railing, a chain like the Kryptonite New York Legend 1515 would be a better fit, though you lose the pre-alarm convenience. For quick stops where visibility and noise matter most, this ABUS delivers exactly that.

A 14mm double locking pin made from hardened stainless steel means this lock is built to stand up to saws, shears, and hammers long after cheaper locks give way. That kind of certified protection, with both SRA approval and Sold Secure Gold, makes it a serious choice for anyone parking a bike in a high-risk area. The 120dB alarm adds a second layer of defense, giving off warning beeps first and then a full blast if the tampering continues, so you get both deterrence and mechanical strength in one package.

Size and weight are the main drawbacks here. At nearly ten inches long, it takes up more room in a bag or pocket than a compact disc lock such as the URBAN UR14S. You will need to buy the transport bracket separately if you want to carry it on the bike. That extra bulk is the price of the double locking mechanism and the heavy stainless build, but for riders who prioritize stopping theft over convenience, it is a worthwhile swap.

A truly waterproof design means this lock keeps working through rain, humidity, and outdoor parking without skipping a beat. The hermetically sealed alarm module and anti-rust treatment let you leave your bike confident in any weather. The 120 dB alarm, paired with a warning pre-alert that chirps before the full blast, gives thieves a reason to move on before they even get started. You can also choose to run it silently if you prefer, and the replaceable electronic module means you won’t toss the whole lock when the battery eventually dies after two to three years.

The 6 mm pin fits most standard brake discs but won’t work with larger rotor holes. If your bike has those, you will need the URBAN UR10 or a similar model with a thicker pin. Compared to the ABUS Granit Detecto X-Plus 8077, which is heavier and bulkier at 1.9 pounds, the UR6 is lighter and more compact, making it easier to carry in a jacket or bag. Just remember that the optional carrying mount is sold separately, so if you want to keep it locked on the bike for convenience, you will need to budget for that extra piece.

A 120dB alarm that blasts for ten full seconds on sustained vibration means this lock doesn’t just block the wheel, it announces the theft attempt to the whole parking lot. The built-in 500mAh rechargeable battery charges in 1.5 hours via Type-C and keeps standby for two to three months, so you’re not hunting for coin cells or buying replacements. That convenience, paired with IP67 waterproofing and a vibration sensor that gives a warning beep before the full alarm, makes it a strong fit for daily commuters who park in shared lots or on city streets and want audible deterrence without fussing with batteries.

The disc lock only fits rotors 7mm or thinner, so it won’t work on many heavy-duty adventure bikes or dual-sport motorcycles with thicker brake discs. For a standard commuter scooter, e-bike, or sportbike, the rechargeable battery and included reminder cable add convenience that some other disc locks don’t offer.

A Sold Secure Gold rating and an 8/10 on Kryptonite’s own security scale mean this chain lock is built for high-risk urban parking, overnight storage, and campus lots where thieves carry bolt cutters. The 10mm six-sided manganese steel links and reinforced oval crossbar lock head are designed to resist cutting and leverage attacks, while the pick-resistant disc cylinder adds to the security. The nylon sleeve helps protect your bike frame from scratches, and the dust cover helps shield the cylinder from moisture and dirt.

At 6.1 pounds, this lock is heavy enough to feel substantial but still portable enough to carry in a bag or strap to a frame. The 3-foot chain gives you enough reach to wrap around a thick pole or post, while keeping the total weight manageable for everyday use. If you need to secure both wheels and the frame to a larger object, a longer chain like the 5-foot Kryptonite New York Legend 1515 offers more flexibility.

An 18mm manganese alloy steel shackle that withstands 90 kN of cutting force makes this compact U-lock a serious barrier against bolt cutters and portable grinders. It is built for riders who need maximum security in a package small enough to stash in a saddlebag or backpack. The dual-deadbolt design locks both sides of the shackle so a pry bar has nowhere to get leverage. The electro-galvanized and PVC-coated finish has been salt spray tested for 300 hours, which means it should resist rust for 6+ years in harsh environments according to the manufacturer.

The compact size, just 5 inches tall with a 1.7-inch internal width, limits where you can lock your motorcycle. You may struggle to loop it around a thick post or through both the frame and a wheel, unlike the Kryptonite New York Legend 1515 chain which offers a 5-foot reach for more anchoring options. If your parking spot has a skinny rail or you only need to secure the disc rotor, this lock delivers exceptional strength in a small footprint. If you need to wrap around a tree or street sign, a chain lock will serve you better.
