A strong motorcycle chain and lock pairs a substantial, hardened chain with a compatible locking mechanism and enough length to secure the bike to a fixed object. The best fit depends on where you park, how much chain you can carry, and whether you need a longer reach or a more compact setup. This roundup compares 10 options, from the 6mm Titanker to the 14mm Kryptonite New York, plus chains from 3.25 feet to 10 feet long.
The KOHLBURG Alcatraz stands out for its stated Sold Secure Diamond approval, 5-foot length, and 6kg weight. Other picks offer thicker links, a U-lock included in the package, or more reach.
Check your anchor point and storage space before choosing: added chain length and heft can make daily handling less convenient.
The KOHLBURG Alcatraz is the leading pick for motorcycle security because it combines a 5-foot chain made from specially hardened manganese-chromium steel with stated Sold Secure Diamond approval. At 6kg, it is a substantial option rather than a light carry-around lock. Choose it if you need extra reach to a suitable fixed anchor and can manage the weight.
Riders prioritizing thicker links in a shorter setup should compare the 14mm Kryptonite New York Fahgettaboudit 1410.

Detailed Reviews: Best Chain And Lock For Motorcycle

#1 · Best Overall
1. KOHLBURG Alcatraz
- dimensions: 59.06 x 3.94 x 1.57 in
- Weight: 6 kg
- Material: Specially hardened manganese-chromium steel
Best for: Maximum-mass chain security.
Why it ranks #1: Its 5-foot chain uses specially hardened manganese-chromium steel and carries stated Sold Secure Diamond approval; the 6kg weight suits security-focused parking.
At 6 kg with a five-foot chain, the KOHLBURG Alcatraz prioritizes substantial hardware and reach for riders securing a motorcycle to a fixed point. Its specially hardened manganese-chromium steel and Sold Secure Diamond designation make it a clear option for buyers focused on security credentials and chain mass.
The five-foot length gives more room to route the chain around a motorcycle and anchor than a shorter chain, while its 6 kg weight signals a substantial item to carry and handle. Specially hardened manganese-chromium steel forms the chain, and the Sold Secure Diamond designation provides a named security credential for comparison. The included padlock and four keys complete the locking setup, with the protective sheath covering the chain during use and storage.
- Five-foot chain provides useful reach
- Specially hardened manganese-chromium steel
- Sold Secure Diamond designation
- Includes padlock and four keys
- At 6 kg, the chain is heavy to carry and handle.
Skip it if you want a lighter 4-foot setup; the Venzio 10mm chain is listed at four feet.
The Alcatraz fits riders who prioritize a five-foot chain and a Sold Secure Diamond designation for anchored motorcycle parking. Its 6 kg weight is an important handling consideration for anyone who needs to carry the lock regularly.

#2 · Thickest Chain
2. Kryptonite New York Fahgettaboudit
- dimensions: 39.37 x 0.55 x 0.55 in
- Weight: 10.8 lb
- Material: Alloy Steel
Best for: High-theft-area chain protection.
Why it ranks #2: The 3.25-foot chain has 14mm triple-heat-treated boron-manganese links and includes a New York disc lock with a 15mm hardened-steel shackle.
The 14mm hexagonal chain and included New York disc lock make Kryptonite’s Fahgettaboudit 1410 a security-focused option for motorcycle parking in high-theft areas. Triple-heat-treated boron manganese steel links and a 15mm hardened-steel shackle pair chain strength with a dedicated locking mechanism.
Narrow inner link widths are specified to defend against leverage attacks, while the New York disc lock adds a 15mm ovalized hardened-steel shackle and a hardened sleeve over the crossbar. Together, these features make the chain-and-disc-lock pairing relevant for riders seeking more than a chain alone. The chain measures 3.25 feet, so it works best when the motorcycle can be positioned close to its anchor; its protective nylon cover uses hook-and-loop fasteners.
- 14mm triple-heat-treated boron manganese steel links
- Narrow inner widths defend against leverage attacks
- Includes New York disc lock with 15mm shackle
- Protective nylon cover has hook-and-loop fasteners
- The 3.25-foot chain restricts reach to nearby anchors.
Skip it if you need more chain reach; the five-foot KOHLBURG Alcatraz extends farther to an anchor.
This Kryptonite set suits riders seeking a chain and disc lock for high-theft-area parking with a nearby anchor. Its 3.25-foot chain length is the key fit boundary, especially when positioning the motorcycle is difficult.

#3 · Hardened U-Lock
3. OKG Heavy Duty Chain Lock
- dimensions: 39.3 x 4.33 x 0.47 in
- Weight: 9 lb
- Material: 3T Manganese Steel, Stainless Steel Cylinder…
Best for: Short-reach hardened chain set.
Why it ranks #3: A 12mm hexagonal manganese-steel chain pairs with a 16mm hardened-steel U-lock and double-deadbolt mechanism; four keys are included.
A 12mm hexagonal chain with a 16mm hardened-steel U-lock gives the OKG set a compact, security-focused pairing for motorcycles and other vehicles. Its 3.3-foot length favors parking close to an anchor, while four included keys provide spares for riders who want more than one key on hand.
The triple-heat-treated boron manganese steel chain uses hexagonal links with narrower inner widths, a feature stated to resist bolt-cutter and leverage attacks. A shrouded lock shell, 16mm hardened shackle, and double-deadbolt mechanism add named protections at the lock itself. At 3.3 feet and 9 pounds, this is a substantial but short-reach set; its nylon sleeve helps keep the chain from directly contacting the motorcycle’s finish.
- 12mm triple-heat-treated boron manganese steel chain
- Hexagonal links with narrower inner widths
- 16mm shackle and double-deadbolt locking mechanism
- Includes four keys and a nylon chain sleeve
- The 3.3-foot chain gives less reach than longer listed options.
Skip it if you need to loop around a distant anchor; the five-foot KOHLBURG Alcatraz offers greater chain reach.
Choose the OKG if your motorcycle can be parked close to its anchor and you value the specified chain and U-lock security features. The 3.3-foot length and 9-pound weight are practical limits to consider before carrying it.

#4 · Longer Reach
4. AKM Motorcycle Chain Lock
- Weight: 4.4 kg
- Material: Acrylonitrile Butadiene Styrene, Alloy Steel…
Best for: Five-foot hex-link chain security.
Why it ranks #4: The 5-foot, 12mm 3T manganese-steel chain includes a 16mm U-lock and four keys, giving it a useful balance of reach and substantial links.
A 12mm hexagonal manganese-steel chain extending five feet gives the AKM room to reach an anchor beyond immediate parking distance. Its 16mm U-lock pairs with the chain, while stated 8KN tension and 17KN shear resistance offer concrete strength figures for riders comparing motorcycle security options.
The five-foot chain gives flexibility to route around a motorcycle and a fixed object, and its 12mm hexagonal links are specified to withstand 8KN tension and 17KN shear force. A 16mm U-lock completes the chain setup, with four keys listed among the components. The rotating-switch lock cylinder is described as helping prevent technical issues and intrusion by rain and dust. A nylon sleeve adds a protective layer between the chain and the motorcycle during use and handling.
- Five-foot chain provides extended reach
- 12mm 3T manganese-steel hexagonal links
- 16mm U-lock included
- Rotating-switch cylinder and nylon sleeve
- The listed component details conflict on key count: features say four, specifications say three.
Skip it if you need an unambiguous listed key count; the four-key OKG set specifies four keys in its components.
The AKM fits riders who need five-foot reach, 12mm hexagonal links, and a paired U-lock for motorcycle anchoring. Check the listing’s conflicting key counts when deciding whether its included keys meet your needs.

#5 · Longest Chain
5. ajee Motorcycle Chain Lock
- dimensions: 13.8 x 7.9 x 3.9 in
- Material: Alloy Steel
Best for: Long-reach motorcycle anchoring.
Why it ranks #5: Its 10-foot chain offers the greatest stated reach in this set and uses 10mm square links; a 17mm U-lock and three keys are included.
A 10-foot square-link chain gives this ajee set exceptional reach for motorcycle owners who need to secure a vehicle to a more distant anchor. Its 10mm carbon-steel chain is paired with a 17mm U-lock, and the listed 6KN tension and 10KN shear figures provide specific strength benchmarks.
The three-meter chain can route around a motorcycle and a fixed object that a shorter chain may not reach, making it useful for varied parking layouts. Square links are described as difficult for theft tools to grip for cutting, and the chain’s 10mm diameter is paired with stated tension and shear figures. A 17mm U-lock completes the set, while the product is also listed for generators, gates, scooters, and equipment. The longer chain requires more room to manage and store.
- 10-foot chain offers extended anchor reach
- 10mm square-link carbon-steel chain
- Includes a 17mm U-lock
- Listed for motorcycles, generators, gates, scooters, and equipment
- The 10-foot chain takes more space to handle and store.
Skip it if you need a compact chain for close parking; the three-foot Titanker is shorter to handle.
The ajee set suits motorcycle owners whose parking arrangement calls for a long route to an anchor or who want to secure varied equipment. Its 10-foot length is useful reach but calls for more storage space.

6. BIGLUFU Motorcycle Chain Lock
- dimensions: 12.6 x 4.7 x 2.9 in
- Weight: 1.9 lb
- Material: Acrylonitrile Butadiene Styrene
Best for: Compact chain-and-U-lock pairing.
Why it ranks #6: The 4-foot, 10mm square-link manganese-steel chain includes a 16mm U-lock and states 6KN tension and 13KN shear resistance.
A 10mm square-link chain paired with a 16mm U-lock gives this BIGLUFU set two distinct locking components for securing a motorcycle. The 4-foot length provides room to reach a nearby fixed point, while a water-resistant nylon sleeve helps protect the finish from chain contact and wear.
The chain’s 3T manganese steel construction and stated 6KN tension and 13KN shear resistance provide concrete security specifications for buyers comparing cut resistance. Its square links are paired with an included 16mm U-lock, so the set offers both chain and shackle locking rather than a chain alone. At 4 feet, it suits parking situations where the anchor is close; the nylon sleeve is water-resistant and helps prevent scratches during handling and use.
- 10mm square-linked 3T manganese steel chain
- Includes a 16mm U-lock
- 4-foot chain reaches nearby anchors
- Water-resistant nylon sleeve helps prevent scratches
- The 4-foot chain limits reach when the anchor is farther away.
Skip it if you need a longer run to reach a distant anchor; the 10-foot ajee chain offers more length.
This set suits riders who want a chain-and-U-lock combination for a motorcycle parked near a usable anchor. Choose it when four feet provides enough reach; its compact length is a boundary for more distant locking points.

View on AmazonWhy it ranks #7: This motorcycle-specific option provides a 4-foot, 10mm heat-treated steel chain with a protective sleeve and a 12mm U-lock.
A 10mm heat-treated steel chain in a four-foot length gives the Venzio a useful balance of reach and substantial links for motorcycle anchoring. Its protective fabric sleeve helps prevent scratches on the frame, and the included U-lock provides a paired locking component for outdoor security.
The stated 10mm chain length of four feet gives room to secure the motorcycle to a nearby fixed object, while the heat-treated steel construction is described as resisting sawing, prying, and leverage attacks. A protective fabric sleeve helps prevent contact scratches on the motorcycle’s frame. The included U-lock means the setup combines a flexible chain with a shackle lock, and the listed weather-resistant feature supports outdoor use. Two keys are included for operating the set.
- 10mm heat-treated steel chain
- Four-foot length for nearby anchors
- Protective fabric sleeve helps prevent frame scratches
- Includes U-lock and two keys
- The listing does not specify the U-lock shackle thickness.
Skip it if you need a stated shackle thickness; the 17mm ajee U-lock provides that figure.
The Venzio suits riders wanting a four-foot chain-and-U-lock setup for outdoor motorcycle parking near an anchor. Its chain thickness is specified, but the listing does not state the U-lock shackle thickness for close comparisons.

8. Kryptonite Keeper 712
- dimensions: 7.09 x 7.09 x 1.18 in
- Weight: 3.7 lb
- Material: Alloy Steel
Best for: Everyday flexible chain locking.
Why it ranks #8: The 4-foot chain has 7mm hardened manganese-steel links, a hardened deadbolt, and a disc-style cylinder; its thinner chain is less substantial than higher-ranked options.
A four-foot chain and hardened deadbolt locking system give the Kryptonite Keeper 712 practical reach for securing a motorcycle to a nearby fixed object. Its 7mm four-sided manganese-steel links and integrated lock focus on everyday anti-theft use, while the patent-pending end link secures the chain to the deadbolt.
The 120cm chain can be routed around a frame and a fixed object, and its four-foot length helps when the anchor is not immediately beside the motorcycle. Hardened manganese-steel links provide the stated chain material, while the end-link design connects directly to the hardened deadbolt to address a critical vulnerability. A disc-style cylinder described as pick- and drill-resistant completes the integrated setup. The 7mm links are thinner than the heavy-duty chains in this roundup.
- Four-foot chain offers flexible routing
- 7mm four-sided hardened manganese-steel links
- End link secures chain to hardened deadbolt
- Disc-style cylinder is described as pick- and drill-resistant
- The 7mm chain is thinner than the 10mm and 12mm options listed here.
Skip it if you want a thicker chain; the 12mm OKG hexagonal chain offers a heavier-link specification.
The Keeper 712 is a fit for riders who want an integrated, four-foot chain lock for everyday motorcycle parking near an anchor. Its 7mm links are the relevant boundary for shoppers prioritizing thicker chain specifications.

9. Titanker Heavy Duty Chain
- dimensions: 9.21 x 4.69 x 1.65 in
- Material: Alloy Steel
Best for: Short-chain everyday locking.
Why it ranks #9: It is listed for motorcycles and includes two keys, but its 3-foot chain has the thinnest stated links here at 6mm.
A three-foot chain with 6mm steel links makes the Titanker a compact option for motorcycle owners who park close to a secure anchor. Its protective cloth sleeve helps guard against scratches and rust, while a dust cover shields the keyhole from dust and the package includes two keys.
The three-foot length suits situations where the motorcycle and anchor are close together, avoiding excess chain to handle in a confined parking spot. Titanker lists 6mm heavy-duty steel links for cut resistance, and the cloth sleeve helps limit rust and scratches during use. A keyhole dust cover adds protection at the lock opening. The supplied care guidance recommends regular lubrication of the lock hole and keyhole to prolong service life, so upkeep is part of ownership.
- Three-foot chain suits nearby anchors
- 6mm heavy-duty steel links
- Protective cloth sleeve helps guard against rust and scratches
- Keyhole dust cover and two keys included
- The 6mm chain is thinner than the larger-link options listed.
Skip it if you need more reach and thicker links; the 12mm AKM chain measures five feet.
This Titanker suits riders wanting a short chain for close-anchored motorcycle parking, with a sleeve and keyhole cover for everyday handling. Its three-foot length and 6mm links define the fit and security trade-offs.

10. GRIFEMA Keyed Chain Lock
- dimensions: 47.24 x 1.57 x 1.57 in
- Weight: 795 g
- Material: Zinc
Best for: Quick snap-locking convenience.
Why it ranks #10: Although listed for motorcycles, it provides a 4-foot chain and two keys without a stated link thickness, and its material listing is zinc.
The GRIFEMA chain snaps together to lock without using the key, which can simplify routine stops when a motorcycle is parked near an anchor. Its four-foot hardened-steel chain comes with a nylon protective cover, while a sliding lock cover helps shield the mechanism from rain and dust.
The key-free snap-to-lock operation streamlines securing the chain at a stop, and two dedicated keys are included for unlocking. A four-foot chain provides room to reach a nearby fixed object, while the nylon sleeve helps protect the motorcycle from scratches where chain and bodywork meet. GRIFEMA also specifies a sliding cover for the lock to protect against rain and dust. These usability and covering features accompany a chain intended for motorcycles, scooters, e-bikes, and other listed uses.
- Locks by snapping together without using a key
- Four-foot hardened-steel chain
- Nylon protective sleeve helps prevent scratches
- Sliding cover protects lock from rain and dust
- The listing gives no chain thickness specification for comparison.
Skip it if you require a stated chain thickness; the 10mm Venzio chain provides that specification.
The GRIFEMA fits riders who value quick key-free locking and a covered lock for routine stops near an anchor. Buyers comparing chain thickness specifications should note that one is not provided in its listing.

View on AmazonAvoid the anchor-point reach trap
A chain that is long enough in theory may still fail to reach your intended anchor once it is routed through the motorcycle. The listed options range from 3.25 feet for the Kryptonite New York Fahgettaboudit to 10 feet for the ajee, with 4-foot and 5-foot choices in between. Measure the actual route from a secure frame point to the anchor, allowing slack for the lock body and the shape of the bike.
Also check whether the anchor is positioned so the chain can stay off the ground; a loose, dragging chain can be easier to handle with tools. The longest option is not automatically best: a 10-foot chain is less convenient to carry and store than a compact chain.
Confirm the usable chain length and opening size of the included lock against your anchor before relying on the setup.
Why chain thickness is only part of the lock
A thick chain does not make the whole setup equally strong if the lock or its connection becomes the easier target. The products pair chains with different locking designs: the OKG has a 16mm hardened-steel shackle and double-deadbolt mechanism, while the Kryptonite New York includes a 15mm ovalised hardened-steel shackle and hardened sleeve over its crossbar. The BIGLUFU pairs its 10mm chain with a 16mm U-lock, and the ajee includes a stated 17mm U-lock.
These figures describe different parts and do not establish a direct strength ranking by themselves. Check how the chain end passes through the lock, whether the lock can close around your anchor, and whether the chain sleeve protects the motorcycle’s finish.
A tight fit can reduce excess movement, but it must still allow practical locking.
How to Choose a Motorcycle Chain Lock
Chain thickness and construction
Look for a chain thickness and material suited to the exposure and handling you expect. Listed links range from Titanker’s 6mm alloy-steel chain and Kryptonite Keeper’s 7mm manganese-steel links to 10mm chains from BIGLUFU and ajee, 12mm chains from OKG and AKM, and the Kryptonite New York’s 14mm links. Shape and treatment vary too: several use square or hexagonal links, and some list hardened or triple-heat-treated steel.
These figures are not a common test result, so they do not prove an exact resistance ranking. Riders who leave a motorcycle in a higher-exposure location may prefer the thicker options, while someone prioritizing easier transport may consider a thinner chain.
Length versus carrying weight
Choose a length that reaches your anchor without making everyday transport impractical. The listed chains span 3.25 feet on the Kryptonite New York, 3 feet on the Titanker, 4 feet on several models, 5 feet on the KOHLBURG and AKM, and 10 feet on the ajee. Weight also varies substantially: the KOHLBURG is listed at 6kg, the OKG at 9 pounds, and the AKM at 4.4kg.
Longer chains can offer more routing options, but the listed weights show why added reach may be burdensome to carry. A fixed parking spot with a nearby anchor may suit a shorter chain; changing parking arrangements or a distant anchor may favour added length.
Lock design and included hardware
Check the included lock’s shackle, locking mechanism, and key count rather than judging the chain alone. The OKG specifies a 16mm hardened-steel shackle and double deadbolt, while the Kryptonite New York lists a 15mm ovalised shackle and hardened crossbar sleeve. The AKM includes a 16mm U-lock and four keys; the KOHLBURG includes a padlock and four keys.
Other products list fewer details, so do not assume all included locks offer equivalent protection. Consider whether the lock can pass through both the chain and your chosen anchor, and whether the key arrangement suits your routine.
Riders who already know their anchor dimensions should check clearance before buying; those with several potential anchor points may prefer a flexible chain-and-lock combination.
Which Motorcycle Chain Lock Should I Choose?
For a security-focused setup with a stated independent approval, choose the KOHLBURG Alcatraz: its 5-foot hardened chain carries Sold Secure Diamond approval, though it weighs 6kg. If you want thicker links in a shorter chain, the 14mm Kryptonite New York Fahgettaboudit has a 3.25-foot chain and a 15mm shackle. For a bundled chain and U-lock with four keys, consider the OKG Heavy Duty Chain Lock, which combines a 12mm chain and 16mm shackle.
Pick the AKM Motorcycle Chain Lock for a 5-foot, 12mm chain, or the ajee Motorcycle Chain Lock when 10 feet of reach matters more than portability. For lighter-duty or less demanding use, compare the 4-foot Kryptonite Keeper 712 or 3-foot Titanker, keeping their thinner links in mind.
Frequently Asked Questions
How should I secure a motorcycle chain to a fixed anchor?
Pass the chain through a strong part of the motorcycle frame and around a fixed anchor that cannot be easily moved or dismantled. Keep the chain off the ground where practical, close the lock fully, and avoid leaving slack that could make it easier to manipulate. Check that the anchor itself is secure.
How long should a motorcycle chain lock be for my parking setup?
Choose a chain long enough to pass through your motorcycle’s frame and around your intended anchor without excessive slack. Measure the route where you park before choosing: the listed options range from 3 feet to 10 feet. Longer chains offer more reach but can be less convenient to carry and handle.
Can I leave a motorcycle chain lock outdoors in wet weather?
Outdoor exposure can lead to moisture and grime collecting on the chain and lock. After wet use, wipe them dry and follow the lock maker’s care guidance, including any instructions for maintaining the locking mechanism. A protective sleeve may help shield a chain, but it does not eliminate the need for upkeep.
What should I compare besides chain length?
Compare link thickness, the included locking hardware, and any stated security approval, as well as chain length. For example, the KOHLBURG Alcatraz has a 5-foot chain and stated Sold Secure Diamond approval, while the Kryptonite New York Fahgettaboudit has 14mm links and a 3.25-foot chain. Consider how much weight you can manage, too.
How can I balance security with portability?
Match the chain to how you park and transport it. The KOHLBURG Alcatraz is a substantial 6kg option with a 5-foot chain, while shorter chains such as the 3-foot Titanker may be easier to handle. Consider whether you can carry the chain regularly and whether its reach suits your anchor.
Final Words
For a security-focused choice with stated independent approval and extra anchor reach, the KOHLBURG Alcatraz is the leading pick, provided its 6kg weight suits your routine. Choose the 14mm Kryptonite New York Fahgettaboudit for thicker links in a shorter setup, or the OKG if you want a chain and U-lock bundle with four keys. Match chain length to your actual parking anchor, and weigh portability against reach before deciding.
