Best Motorcycle Lock Chain: Compare 10 Security Chains

#1 · Best Overall

1. KOHLBURG Alcatraz 7ft

• dimensions: 82.68 x 3.94 x 1.57 in
• Weight: 8 kg
• Material: Specially hardened manganese-chromium steel

Best for: Long-reach motorcycle anchoring.

Why it ranks #1: This motorcycle-specific 7ft chain lists Sold Secure Diamond approval and includes a padlock and four keys, though its 8 kg weight limits portability.

A 7-foot chain gives the KOHLBURG Alcatraz unusually broad reach for securing a motorcycle to an anchor set farther away. Its specially hardened manganese-chromium steel construction and Sold Secure Diamond approval make it a serious option for buyers who want a long chain and a high-security designation.

The 7-foot length gives riders more flexibility when the anchor point is not immediately beside the vehicle, while the 8kg listed weight signals a substantial chain that is better suited to stationary security than effortless daily carrying. The package includes a security padlock and four keys, so the core locking components arrive together. Its hardened manganese-chromium steel construction supports the heavy-duty positioning; plan storage and transport around the chain’s mass and 82.68-inch length.

Skip it if you want a shorter chain that is easier to carry; the 5-foot KOHLBURG Alcatraz weighs 6kg.

The Alcatraz 7-footer fits owners securing a motorcycle to a more distant fixed point and prioritizing its Sold Secure Diamond approval. Its 8kg weight and long profile call for a storage and transport plan.

#2 · Best Shorter Diamond Chain

2. KOHLBURG Alcatraz 5ft

• dimensions: 59.06 x 3.94 x 1.57 in
• Weight: 6 kg
• Material: Specially hardened manganese-chromium steel

Best for: Heavy security with midrange reach.

Why it ranks #2: Its 5ft manganese-chromium steel chain also lists Sold Secure Diamond approval and includes four keys and a padlock, with less reach than the 7ft version.

The KOHLBURG Alcatraz combines a 5-foot chain with Sold Secure Diamond approval, balancing meaningful anchoring reach with a shorter profile than its 7-foot counterpart. Specially hardened manganese-chromium steel gives buyers a heavy-duty material specification for securing a motorcycle to a fixed point.

At 5 feet, the chain can accommodate more anchor positions than compact chains while remaining shorter than the 7-foot Alcatraz option. Its 6kg listed weight is substantial, so it makes more sense for planned security than frequent casual carrying. The package includes a padlock and four keys, providing the core components for locking without a separate padlock purchase. The hardened manganese-chromium steel and Sold Secure Diamond approval support buyers prioritizing security credentials alongside useful reach.

Skip it if you need extra reach around a distant anchor; the 7-foot KOHLBURG Alcatraz extends the chain length.

This Alcatraz suits motorcycle owners who want Diamond-approved security and 5 feet of anchoring reach. Its 6kg weight favors a planned parking setup, so consider carrying demands as well as anchor distance.

#3 · Best High-Security Set

3. Kryptonite New York Fahgettaboudit 1410

• dimensions: 39.37 x 0.55 x 0.55 in
• Weight: 10.8 lb
• Material: Alloy Steel

Best for: High-risk-area chain security.

Why it ranks #3: The set pairs a 3.25ft chain of 14mm heat-treated boron manganese links with a New York disc lock and 15mm hardened steel shackle.

Fourteen-millimeter, six-sided links of triple heat-treated boron manganese steel give the Kryptonite New York Fahgettaboudit chain a security-focused foundation. Its 3.25-foot length suits riders who can lock close to an anchor and want the included New York disc lock integrated into the security setup.

The narrow inner width of each chain link is specified to defend against leverage attacks, while the included disc lock adds a 15mm ovalized hardened-steel shackle and a hardened-steel sleeve over its crossbar. Together, chain and lock create a matched system rather than a chain awaiting a separate padlock. A protective nylon cover with hook-and-loop fasteners helps keep the chain covered; at 15.25 pounds in the feature listing, portability is a substantial tradeoff.

Skip it if you need a lighter chain for frequent carrying; the 1.9-pound BIGLUFU 4-foot chain is the lighter listed option.

This suits riders prioritizing a substantial chain-and-disc-lock combination in a high-theft area. Its 3.25-foot reach and listed 15.25-pound weight make anchor distance and carrying demands important fit considerations.

#4 · Thickest Links

4. OKG Motorcycle Chain Lock

• dimensions: 39.3 x 4.33 x 0.47 in
• Weight: 9 lb
• Material: 3T Manganese Steel, Stainless Steel Cylinder…

Best for: Thick-link chain with shrouded U lock.

Why it ranks #4: It combines 12mm hexagonal manganese-steel links with a hardened-steel U-lock and four keys in a motorcycle-focused 3.3ft set.

Twelve-millimeter hexagonal links and a hardened-steel U lock give the OKG a substantial chain-and-lock combination for motorcycle, e-bike, moped, or ATV security. Its 3.3-foot length suits riders locking close to an anchor, while the narrow inner link width is specified to hinder leverage attacks.

The triple heat-treated boron manganese steel chain combines a thick 12mm profile with narrower inner widths intended to prevent bolt cutters and leverage attacks from gaining purchase. Its U lock adds a shrouded shell, a 16mm hardened-steel shackle, and a double deadbolt mechanism. Together, those features make the set more complete than a chain alone. Four keys are included, and the listed 9-pound weight means buyers should consider how often they will transport it.

Skip it if you need more reach than 3.3 feet; the 4-foot BIGLUFU chain offers a longer listed chain.

The OKG fits riders seeking thick chain links and a matching shrouded U lock for a nearby anchor. Its 3.3-foot length and 9-pound weight are key considerations for placement and transport.

Listed on Amazon as: OKG Heavy Duty Motorcycle Chain Lock, 4 Keys, 3.3 ft x 1/2 in (12mm) Thick Hexagonal Cinch Security Chain with 18mm Cut Proof Hardened Alloy Steel U Lock for Motorcycles, E-Bikes, Mopeds, ATVs, Etc.

#5 · Longest 12mm Chain

5. BIGLUFU 12mm Chain Lock

• dimensions: 59.06 x 1.97 x 5 in
• Weight: 9.9 lb
• Material: Alloy Steel

Best for: Longer 12mm BIGLUFU chain.

Why it ranks #5: The 5ft chain has 12mm square links and a U-lock, offering more reach than the shorter 12mm OKG and Kryptonite sets.

A 5-foot length of 12mm square-linked 3T manganese steel gives this BIGLUFU more reach and thicker links than its 4-foot sibling. The chain’s stated 8KN tension and 17KN shear-force resistance support riders seeking a robust chain for a motorcycle or bicycle near a suitable anchor.

The 12mm links and stated strength figures provide a substantial security profile, while the 5-foot length can help reach anchors that a shorter chain cannot. A water-resistant nylon sleeve helps protect the chain from scratching surfaces, making contact with a vehicle less abrasive. The listing specifies a U lock and four keys, so the chain is supplied with a locking component and spare access. At 9.9 pounds, its added length and thickness come with a carrying burden.

Skip it if you need a lighter chain for regular transport; the 4-foot BIGLUFU weighs 1.9 pounds.

This BIGLUFU suits riders who want 12mm links, a 5-foot reach, and an included U lock for securing near a fixed anchor. Its 9.9-pound weight makes transport an important part of the decision.

#6

6. ZEIXIHY 10mm Chain Lock

• dimensions: 39.37 x 3.15 x 0.39 in
• Weight: 2.5 kg
• Material: Alloy Steel

Best for: Multi-vehicle chain and U lock.

Why it ranks #6: This 3.9ft, 10mm hardened-steel chain includes a U-lock and four keys, making it a motorcycle-suitable package with moderate reach.

A 3.9-foot, 10mm hardened-steel square chain arrives with a heavy-duty U lock and four keys, giving the ZEIXIHY a ready-to-use two-part locking setup. Its listed applications span motorcycles, e-bikes, scooters, bicycles, gates, and fences, supporting buyers securing more than one kind of property.

The alloy-steel chain and accompanying U lock provide the main locking components in one package, while the 10mm square links are presented as cut resistant. Its 3.9-foot reach gives some flexibility for attaching a vehicle to a nearby fixed point, and the listed 2.5kg weight is a practical factor for riders carrying it. Four keys provide spares for access. The broad recommended-use list also makes it relevant for gates, fences, grills, ladders, and outdoor equipment.

Skip it if you need a 7-foot chain for a distant anchor; the KOHLBURG Alcatraz offers that longer reach.

The ZEIXIHY suits riders who want chain and U lock together for a motorcycle, scooter, or e-bike and may secure other equipment too. Check that 3.9 feet reaches the intended anchor.

#7

7. BIGLUFU 10mm 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 security.

Why it ranks #7: Its 4ft chain uses 10mm square manganese-steel links and includes a 16mm U-lock, but it is thinner than the leading options.

A 10mm square-linked chain made from 3T manganese steel gives the BIGLUFU a substantial security core in a 4-foot format. That length can help riders secure a motorcycle or bike to a nearby anchor while keeping the setup more manageable than the much longer chains in this lineup.

The chain’s stated 6KN tension and 13KN shear resistance provide concrete strength specifications, while its 10mm links give the lock a robust profile for everyday securing. A water-resistant nylon sleeve helps shield the chain and reduce scratching against the vehicle or nearby surfaces. The included 16mm U lock completes the locking setup, so buyers get both chain and lock rather than needing to source a separate locking component. At 4 feet, plan around reachable anchors.

Skip it if you need to reach a distant anchor; the 7-foot KOHLBURG Alcatraz offers more chain length.

Choose the BIGLUFU for a rider seeking a steel chain and included U lock in a 4-foot package. It suits nearby anchoring, but measure the route to your anchor before relying on its reach.

#8

8. WARLION 15ft Security Chain

• dimensions: 12 x 5.12 x 5.12 in
• Weight: 19 lb
• Material: 3T Hardened Alloy Steel, Nylon, Zinc

Best for: Extended-reach cinch chain.

Why it ranks #8: The 15ft, 9mm case-hardened chain and cinch ring provide exceptional reach, but the listing does not include a lock.

A 15-foot length and integrated cinch ring make the WARLION useful when a motorcycle or other equipment needs to be secured around a larger object. Its 9mm case-hardened steel chain is specified to resist cutting, sawing, and hammering, while the ring extends the effective locking length.

The cinch ring helps users tighten the chain around motorcycles, e-bikes, generators, ATVs, and other listed equipment without being limited to a simple end-to-end loop. At 15 feet, it can serve multiple items or reach a more distant anchor, while the 19-pound listed weight makes carrying a meaningful consideration. A removable nylon sleeve and toolbag are included, supporting chain protection and storage. The included components list does not include a lock, so buyers need a compatible locking method.

Skip it if you want a complete chain-and-lock set; the ZEIXIHY CHL-1 includes a U lock and four keys.

This fits owners securing equipment to bulky or distant anchors who value cinch-ring flexibility and have a separate lock. Its 19-pound listed weight and chain-only component list are important practical boundaries.

#9

9. Titanker 6mm Chain Lock

• dimensions: 9.21 x 4.69 x 1.65 in
• Material: Alloy Steel

Best for: Short chain for nearby fixtures.

Why it ranks #9: It includes keys and a 3ft protective-sleeved chain, but its 6mm links and bicycle-oriented listing make it a weaker motorcycle fit.

The Titanker’s 3-foot chain and protective cloth sleeve make it a compact choice for locking to a nearby bike rack, gate, or other listed fixture. Its 6mm heavy-duty steel links are described as cut-resistant, and the package includes two keys for the keyed lock.

The short 3-foot length keeps the chain manageable for close anchor points, but requires the vehicle and fixture to be positioned within reach. A protective cloth sleeve helps guard the chain against rust and scratches, while a dust cover protects the keyhole from dust. The listing recommends regular lubrication of the lock hole and keyhole to prolong service life, adding a straightforward maintenance step. Its stated uses include bikes, motorcycles, doors, gates, fences, and grills.

Skip it if you want thicker chain links; the BIGLUFU 4-foot model uses 10mm square-linked chain.

Choose the Titanker for a short, keyed chain around a nearby fixture, with a sleeve and keyhole dust cover. Its 3-foot reach and 6mm links make anchor distance and chain thickness the main fit considerations.

#10

10. Kryptonite Keeper 785

• dimensions: 1.5 x 2.5 x 18.25 in
• Weight: 1.41 kg
• Material: Alloy Steel

Best for: Portable short-chain locking.

Why it ranks #10: This portable 2.8ft chain has 7mm manganese-steel links and a disc-style cylinder, but its listing identifies it as a bicycle lock.

The Kryptonite Keeper 785 pairs a 2.8-foot chain with a patented end-link design that connects directly to a hardened deadbolt. That arrangement addresses a chain connection point while keeping the overall format short enough for riders who lock near an anchor and value portability.

Its 7mm four-sided manganese-steel links are specified to resist cutting and leverage attacks, while the high-security disc-style cylinder is resistant to picking and drilling. The patented end link secures the chain to the hardened deadbolt, eliminating a weak point in that connection. A rubber coating helps protect contacted surfaces from scratches and wear. The short 2.8-foot length works best when the anchor is close, and the listed 1.41kg weight supports easier carrying than heavier chains.

Skip it if you need to loop around a distant anchor; the 4-foot BIGLUFU chain provides more length.

Choose the Keeper 785 for a rider who wants a portable, short chain with an integrated deadbolt connection and disc-style cylinder. Its 2.8-foot reach makes anchor placement the key fit consideration.
