Best Motorcycle Locks To Prevent Theft: 10 Options Compared

#1 · Best Overall

1. YOHOOLYO Alarm Disc Lock

• Weight: 12.32 oz

Best for: Alarm-minded motorcycle parkers.

Why it ranks #1: Motorcycle-focused disc lock combines a 7 mm pin, stated 110 dB alarm and included 5 ft reminder cable for a useful layered deterrent.

A 110 dB alarm gives the YOHOOLYO disc lock an audible deterrent, while its 7 mm pin lets riders position it at 360 degrees. That pairing suits motorcycle, bicycle, and scooter owners who want a compact wheel-locking step with an alert built in.

The all-metal construction and waterproof description support use as an outdoor disc brake lock, while the alarm adds a sound-based warning when the locked vehicle is disturbed. Its 7 mm pin can be set at 360 degrees, giving more placement flexibility around a compatible disc. The title also lists a 5 ft reminder cable and carry pouch, useful for remembering the lock before moving off and keeping it together between stops. Compatibility is listed for motorcycles, bicycles, and scooters.

Skip it if you need a chain to secure the bike to a fixed anchor; NDakter’s U-lock set includes a 4 ft chain.

Choose it if you park a motorcycle, bicycle, or scooter and want an audible alert in a portable disc-lock format. The 7 mm pin still requires a compatible brake disc, and it is not a fixed-anchor chain.

#2 · Hardened Disc Lock

2. Kryptonite Evolution Disc Lock

• Weight: 1.4 lb
• Material: manmade
• Dimensions: 3.15 x 1.18 x 1.18 in

Best for: Compact motorcycle disc-lock users.

Why it ranks #2: Its 13 mm hardened-steel shackle, double deadbolt and compact rotor-fitting plate make it a strong key-operated disc-lock alternative.

A 13 mm hardened steel shackle and flat-top plate make the Kryptonite Evolution Compact a compact disc lock with a specified rotor attachment approach. Its plate can attach to the rotor spider in more than one location, while the design requires two cuts to defeat.

The hardened double deadbolt is intended to add protection against twist attacks, complementing the shackle’s stated resistance to bolt cutters and leverage. Its compact 3.15 by 1.18 by 1.18 inch dimensions make it suited to carrying as a disc-lock option rather than as a chain for reaching an anchor. The package includes three stainless-steel keys and a replaceable LED key fob. A bright orange reminder is also listed to prompt removal before riding.

Skip it if you need chain reach to a fixed anchor; Kryptonite Keeper 785 provides a 2.8 ft chain.

Choose it if you want a compact disc lock with a 13 mm shackle, double-deadbolt design, and reminder. It secures at the rotor rather than reaching an anchor, so that distinction should match your parking setup.

#3 · Helmet Lock Combo

3. Matework Motorcycle Lock

• Weight: 0.55 kg
• Material: CNC aluminum alloy

Best for: Riders securing helmet and bike.

Why it ranks #3: This motorcycle-specific CNC aluminum alloy lock includes a separate helmet lock and is described as weather resistant and cut resistant.

The included helmet lock gives the Matework package a second job beyond motorcycle security: riders can secure a helmet as well as the bike. Its CNC aluminum-alloy construction and anodized surface are specified alongside weather resistance and corrosion resistance for outdoor use.

The package lists a motorcycle lock, helmet lock, and key, making it useful for riders who want to keep helmet security in the same kit as their bike lock. Matework describes the lock as waterproof and cut-resistant, while the anodized CNC aluminum-alloy surface is presented as corrosion-resistant. The product information also mentions an anti-scratch pad and four replacement adhesive tapes if the pad’s adhesion does not work, an installation detail worth considering before use.

Skip it if you need a stated handlebar diameter range; TOKCKYBL lists adjustable fit for 1.4–1.6 inch handlebars.

This package fits riders who want a motorcycle lock and a separate helmet-lock component, with corrosion-resistant construction for outdoor use. The listing does not give a locking-point dimension, so its fit may be less straightforward to assess in advance.

#4 · Handlebar Lock

4. TOKCKYBL Handlebar Lock

• Weight: 0.55 kg
• Material: CNC Auminum Alloy
• Dimensions: 5.9 x 4.8 x 1.4 in

Best for: Handlebar-and-helmet security.

Why it ranks #4: The two-in-one lock includes a detachable helmet lock and fits stated handlebar diameters of 1.4 to 1.6 inches.

An adjustable handlebar lock and detachable helmet lock combine bike and gear security in TOKCKYBL’s two-in-one package. The stated 1.4–1.6 inch handlebar fit gives riders a concrete compatibility range, while the weather-resistant coating suits outdoor parking.

The hardened aluminum-alloy construction is paired with a tamper-proof key cylinder and features listed to resist cutting and drilling. Its adjustable fit is specified for handlebars measuring 1.4 to 1.6 inches, so riders can compare that range with their bike before choosing it. The detachable helmet lock adds a separate way to secure gear when parked. The product is also listed for dirt bikes and snowmobiles, extending its stated use beyond standard motorcycles.

Skip it if your handlebar diameter falls outside 1.4–1.6 inches; Matework’s listing does not specify a handlebar diameter range.

Suitable for riders whose handlebars fall within the stated 1.4–1.6 inch range and who want a detachable helmet-lock component too. Check the handlebar dimension first; this lock’s stated compatibility is specific rather than universal.

#5 · Longest Chain

5. FIGODE Stainless Chain Lock

• Material: Stainless Steel
• Dimensions: 47.2 x 23.6 x 1.25 in

Best for: Weather-exposed chain-lock owners.

Why it ranks #5: Its 110 cm stainless-steel chain and stainless-steel lock head suit riders seeking a flexible tether, with four same keys included.

A 110 cm stainless-steel 304 chain gives FIGODE riders substantial reach while its rust-resistant material is specified for outdoor and wet conditions. The luminous nylon cover adds a visible, protective layer, and the matching stainless-steel lock head comes with four keys.

The chain measures 110 cm, with a stated total length of 120 cm including the lock, allowing more reach to an anchor than a short chain. Stainless steel 304 is listed for both chain and lock, and the description says it can be used underwater and in bad weather. A brass cylinder and snake-shaped keyway are intended to help keep foreign matter from entering the cylinder. Four brass keys are included for sharing or backup.

Skip it if you need a specified heavy-duty link thickness; NDakter lists a 6 mm chain for its U-lock set.

A good fit for riders who need 110 cm of chain reach and want stainless-steel construction for outdoor or wet use. Chain thickness is not stated in the supplied details, which may matter when comparing security specifications.

#6

6. OKG Heavy Duty U-Lock

• Weight: 2 lb
• Material: 3T Hardened Alloy Steel U-Shackle, Reinforced…
• Dimensions: 4.4 x 1.7 x 5 in

Best for: Compact high-security U-lock users.

Why it ranks #6: An 18 mm hardened manganese-alloy shackle and dual-deadbolt mechanism provide a substantial U-lock option, though no chain is included.

An 18 mm hardened manganese-alloy shackle and dual-deadbolt mechanism are the OKG lock’s defining security features. The compact 4.4 by 1.7 by 5 inch form suits motorcycle, ATV, trailer, and e-bike owners seeking a small U-lock without a chain.

OKG lists 90 kN cutting force and 75 kN tensile strength, with testing to ART 4-Class standards; those figures give security-focused buyers concrete resistance specifications to weigh. The dual-deadbolt design is stated to block pry tools, bolt cutters, and portable grinder attacks. Its small dimensions may help with storage, but also limit how much can fit inside the shackle. Four keys are included, and the product is identified as weatherproof and rust-resistant.

Skip it if you need extra reach around a remote anchor; NDakter’s set includes a 120 cm chain with its U-lock.

Consider it if your motorcycle, ATV, trailer, or e-bike can be secured within a compact U-shackle and you prioritize its listed strength specifications. It does not include a chain, so the locking point must fit its small opening.

#7

7. NDakter U-Lock and Chain

• Material: Brass
• Dimensions: 7.09 x 3.15 x 1.18 in

Best for: Chain-and-U-lock commuters.

Why it ranks #7: This set pairs an 18 mm hardened-steel shackle with a 120 cm, 6 mm chain and three keys for more flexible securing.

An 18 mm hardened-steel shackle paired with a 4 ft chain gives the NDakter set two locking components for securing a wheel and reaching an anchor. Its large U shape suits riders of ebikes, scooters, mopeds, and fat-tire dirt bikes who need more than a standalone disc lock.

The U-lock has a 5.5 by 7 inch internal opening, a useful fit reference when checking a frame, wheel, or anchor combination. Its 6 mm by 120 cm chain extends the locking reach, so a rider can connect the bike to a fixed point where the setup permits. The set includes three keys and uses a double-open design. At 1.6 kg, it is a substantial carry item rather than a minimal pocket lock.

Skip it if you want a lighter disc-lock setup with an alarm; YOHOOLYO’s 110 dB disc lock is the more direct fit.

A practical choice for riders who want both a U-lock and chain to secure an ebike, scooter, or motorcycle near an anchor. Check the 5.5 by 7 inch opening against your locking arrangement and account for its 1.6 kg weight.

#8

8. Kryptonite Keeper 785 Chain

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

Best for: Short manganese-steel chain users.

Why it ranks #8: A 2.8 ft chain made from 7 mm manganese steel has four-sided links and a disc-style cylinder, but offers less reach than longer chains.

Seven-millimeter four-sided manganese-steel links give the Kryptonite Keeper 785 a defined chain construction for riders securing a motorcycle or bike. Its patented end-link design joins the chain to a hardened deadbolt, addressing a connection point the product describes as a potential weak link.

The 2.8 ft chain works best when the anchor is close enough for its limited reach; its shorter length can also make carrying and positioning simpler than a longer chain. A high-security disc-style cylinder is described as resistant to picking and drilling, while the hardened deadbolt adds holding power. The chain’s rubber coating helps protect surfaces from scratches and wear. Weighing 1.41 kg, it is a substantial chain rather than a lightweight pocket option.

Skip it if you need a longer chain to reach a remote anchor; FIGODE’s 110 cm stainless-steel chain extends farther.

A fit for riders who can park close to an anchor and want a chain with a specified end-link and cylinder design. Its 2.8 ft length is the key boundary when deciding whether it can reach your locking point.

#9

9. Titanker Heavy Duty Chain

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

Best for: Short-reach chain-lock buyers.

Why it ranks #9: The 3 ft alloy-steel chain has 6 mm links and a protective sleeve, but its listed specifications provide fewer motorcycle-specific details.

A 3 ft length and 6 mm steel links make the Titanker a straightforward chain-lock option for riders who need a short reach. Its protective cloth sleeve helps guard against scratches and rust, while the dust cover protects the keyhole between uses.

The 3 ft chain can secure a motorcycle or bike where the available anchor sits within reach, and the alloy-steel links are described as cut-resistant. Its cloth sleeve helps keep the chain from scratching nearby surfaces and protects it from rust, which is useful when carried or used outdoors. The dust cover shields the keyhole from dust, while the listing recommends regular lock-hole and keyhole lubrication to prolong service life. Two keys are included.

Skip it if you need a longer stainless-steel chain; FIGODE’s 110 cm chain offers greater reach and is specified as 304 stainless steel.

A sensible fit for riders who want a compact chain for a nearby anchor and value a sleeve and keyhole cover. Its 3 ft length limits reach, and regular lubrication is recommended for the lock and keyhole.

#10

10. Sportneer Combination Chain

• Weight: 0.64 kg
• Material: Alloy Steel, Zinc
• Dimensions: 4.72 x 5.91 x 2.76 in

Best for: Keyless chain-lock riders.

Why it ranks #10: Its keyless five-digit combination and 3.2, 3.6 or 4 ft chain lengths offer convenience, but the listing is primarily bicycle-focused.

A resettable five-digit combination replaces keys on this Sportneer chain lock, giving riders a keyless way to secure a motorcycle, scooter, or bicycle. The listing states up to 100,000 possible combinations and offers chain lengths of 3.2, 3.6, or 4 ft.

Choosing among three listed lengths lets buyers balance carrying size with the reach needed for a particular parking point. The five-digit combination avoids carrying a separate key, while its resettable design supports setting a personal code. Alloy steel and zinc are the listed materials, and the lock is described as heavy duty. The product information does not give chain thickness in the supplied details, so buyers comparing chain dimensions have less specification detail here than on some alternatives.

Skip it if you require a stated chain thickness; Titanker lists its chain links as 6 mm thick.

Choose it if avoiding keys matters and one of the three chain lengths suits your motorcycle, scooter, or bicycle parking setup. Its listed materials are alloy steel and zinc, but chain thickness is not stated in the supplied details.
