Best Helmet Locks For Motorcycles: Compare 10 Options

#1 · Best Overall

1. UR140 Motorcycle Helmet Lock

• Weight: 0.22 kg
• Material: Alloy Steel, Rubber
• Material Type: Alloy Steel, Rubber

Best for: Keyless riders carrying extra gear.

Why it ranks #1: Its kit combines a four-digit keyless carabiner, steel cable, and T-adapter, offering several attachment options in a portable package.

A three-part kit pairs a combination carabiner with a T-bar helmet adapter and flexible steel cable, letting riders secure a helmet without a key. The compact lock can also be placed at different motorcycle points, including a handlebar, grip, or handle, while its rubber protection helps prevent scratches.

The T-bar extension provides a helmet-specific attachment, while the steel cable gives riders another way to secure gear; together, they make the kit more versatile than relying on the carabiner alone. Its four-digit combination avoids carrying a key, and the code is customizable. At 0.22 kg and about 4.33 by 2.76 by 0.79 inches, it is sized to carry along, though the cable’s length is not specified.

Skip it if you need a stated cable length before deciding whether it can reach your motorcycle’s attachment point.

A good match for riders who want a keyless helmet lock with both a T-bar adapter and cable for varied attachment points. Consider the unspecified cable length if your parking setup requires a particular reach.

#2

2. Kewig Aluminum Helmet Lock

• Weight: 6.1 oz

Best for: Handlebar-mounted lock seekers.

Why it ranks #2: The 6061 aluminum lock clamps to 0.875, 1, or 1.125-inch round handlebars and includes rubber inserts and an Allen wrench.

CNC-machined 6061 aluminum alloy and a zinc-alloy cylinder with a double anti-theft structure distinguish this Kewig lock from cable tethers. It clamps to supported round handlebars and uses a customizable three-digit combination, giving riders a mounted helmet-lock option without needing to carry a separate cable for each stop.

The lock supports round handlebars measuring 0.875, 1, or 1.125 inches, with replaceable TPU inserts for 22 mm and 25 mm bars to accommodate those sizes. An included Allen wrench supports installation without a separate tool purchase. The hard-anodized aluminum is described as corrosion-resistant, and the cylinder’s double structure is specified to resist cutting, drilling, prying, and bending. Its three-digit code is customizable, with 000 as the default.

Skip it if you need a flexible cable to reach different attachment points; Urban UR140 includes a steel cable and T-bar adapter.

Best suited to riders whose motorcycle has a supported round handlebar size and who want a mounted, combination-operated helmet lock. The handlebar diameter range is the central fit consideration before choosing this format.

#3 · Longest Stated Cable Reach

3. MEETLOCKS Cableloop Lock

• Weight: 7.04 oz
• Material: Alloy Steel, Polyvinyl Chloride, Zinc
• Material Type: Alloy Steel, Polyvinyl Chloride, Zinc

Best for: Riders needing a long retractable loop.

Why it ranks #3: Its retractable steel cable extends up to 1000mm, and the resettable four-digit combination avoids carrying a key.

A cable that stretches up to 1,000 mm gives the MEETLOCKS combination lock reach for securing a helmet or other gear around varied attachment points. Its four-digit resettable code avoids keys, while the zinc-alloy hook and PVC-wrapped cable help make the lock convenient to carry and less prone to scratching surfaces.

The retractable cable extends up to 1,000 mm, offering more reach than a short fixed loop when the available motorcycle attachment point is farther from the helmet. A resettable four-digit combination provides keyless access, and the zinc-alloy hook forms the locking connection. The PVC cable covering helps guard a helmet or vehicle surface against scratches. At 144 g, the lock can be carried in a pocket or backpack between stops.

Skip it if you prioritize the lightest listed cable lock; ROCKBROS T512-T609 is listed at 124 g.

This suits riders who need a retractable, longer-reach cable and keyless access for helmets or other gear. Its 144 g weight and cable-based format are relevant boundaries for anyone prioritizing the lightest possible carry.

#4 · Best Carabiner Extras

4. BigPantha Helmet Lock

• Material: Rubberized Aluminium, Nickle, Plastic Coated…
• Material Type: Rubberized Aluminium, Nickle, Plastic Coated…

Best for: Riders protecting helmet and gear.

Why it ranks #4: This combination carabiner lock includes a carry pouch and small flashlight, plus a plastic-coated steel wire for securing gear.

A rubberized D-ring carabiner and coated steel cable give this BigPantha lock a scratch-conscious way to secure a helmet, jacket, gloves, or bag. The combination PIN mechanism avoids carrying a key, and the included carry pouch helps keep the lock together when it is not attached to gear.

The rubberized sleeve over the carabiner helps prevent scratches on a helmet or motorcycle, while the plastic-coated steel wire provides the tether for gear. Its stated uses extend beyond helmets to jackets, gloves, and bags, so the same lock can secure several kinds of riding items. A combination PIN mechanism supports keyless access, and the included pouch provides a place to carry the lock between stops. The supplied information does not give a cable length.

Skip it if you need a stated cable reach to plan an attachment; MEETLOCKS MTP0001 lists a cable extending up to 1,000 mm.

Consider this for riders who want a scratch-conscious combination lock for helmets and other small riding gear, with a pouch for carrying it. The unspecified cable length matters if your parking setup requires a particular reach.

#5 · Best Keyed Cable Lock

5. Master Lock 99

• Material: Plastic, Vinyl
• Material Type: Plastic, Vinyl

Best for: Key-lock traditionalists needing a cable.

Why it ranks #5: The 14-inch vinyl-covered cable has a 5mm diameter, a four-pin tumbler, and a dead-locking mechanism.

A 14-inch vinyl-covered cable and keyed four-pin tumbler give the Master Lock 99 a straightforward, key-operated helmet-lock format. The package includes the lock and two keys, while a plastic cover helps prevent helmet scratches and the dead-locking mechanism is specified to prevent rapping the lock open.

The 14-inch cable has a 5 mm diameter, offering a short tether for securing a helmet near a motorcycle attachment point. Vinyl covers the cable, and the plastic lock cover helps protect the helmet’s finish during use. A four-pin tumbler operates with the two included keys, while the dead-locking mechanism adds a specified defense against rapping the lock open. This is a compact cable approach rather than a handlebar-mounted lock.

Skip it if you need a longer cable loop; Master Lock 719KA is listed with a three-foot cable.

A sensible choice for riders who prefer a keyed cable lock and need only a short reach to secure a helmet. Its 14-inch length is the main fit consideration for the intended motorcycle attachment point.

#6 · Best Two-Lock Set

6. Master Lock 99KA

• Material: Plastic
• Material Type: Plastic

Best for: Riders wanting two keyed locks.

Why it ranks #6: The listing supplies two keyed-alike cable locks and four keys, each with a 14-inch, vinyl-covered cable for helmet use.

Two keyed-alike cable locks and four shared keys make this Master Lock set useful when a rider wants a lock for more than one helmet or needs a spare. Each 14-inch vinyl-covered cable offers a straightforward way to secure a helmet and deter casual theft or pranks while parked.

The 14-inch cable is 5 mm in diameter, giving a compact loop for securing a helmet without carrying a longer, bulkier cable. A four-pin tumbler uses keys rather than a combination, and the pair is keyed alike, so either lock can be opened with the included keys. The vinyl covering and plastic lock cover help prevent scratching, while the two-lock, four-key set supports shared use or a spare key.

Skip it if you need a cable longer than 14 inches; Master Lock 719KA is listed with a three-foot cable.

Consider this set if you want two key-operated helmet locks with shared keys for motorcycles or multiple riders. Its 14-inch cable is the key fit boundary, so check that length against your intended attachment point.

#7

7. TOKCKYBL Handlebar Lock

• Weight: 0.55 kg
• Material: CNC Auminum Alloy
• Material Type: CNC Auminum Alloy

Best for: Riders securing bike and helmet.

Why it ranks #7: Its two-in-one design pairs a motorcycle lock with a detachable helmet lock, but the stated handlebar range is 1.4 to 1.6 inches.

A two-in-one setup combines a heavy-duty motorcycle lock with a detachable helmet lock, letting riders secure the bike and helmet through one system. Its adjustable handlebar lock fits stated diameters of 1.4 to 1.6 inches, while a tamper-proof key cylinder and weather-resistant coating address outdoor use.

The CNC aluminum-alloy construction and tamper-proof key cylinder are specified to resist cutting and drilling, while the weather-resistant coating supports use in outdoor conditions. The detachable helmet lock adds a separate helmet-securing function to the main motorcycle lock, so riders can address both items with the same system. The adjustable handlebar fit is limited to diameters from 1.4 to 1.6 inches, making that measurement an important installation check.

Skip it if your handlebar is outside 1.4–1.6 inches; Kewig CKB-4 supports round bars from 0.875 to 1.125 inches.

A fit for riders seeking a combined motorcycle and helmet locking setup, especially for outdoor parking. Check the stated 1.4–1.6-inch handlebar range first; this system’s handlebar fit is its key boundary.

#8

8. Hiplok Z LOK Combo

• Weight: 82 g
• Material: Plastic Metal
• Material Type: Plastic Metal

Best for: Lightweight café-stop tether users.

Why it ranks #8: The 82g security tie has a resettable three-digit code, steel core, 45cm locking length, and an optional carry bracket.

A steel-core security tie with a 45 cm locking length gives the Hiplok Z LOK Combo a lightweight way to hold a helmet or bicycle during a brief stop. Its resettable three-digit combination avoids carrying a key, and the included optional bracket provides a carrying mount for bicycle use.

The steel core adds reinforcement within a flexible tie format, while the 45 cm locking length sets the available reach for wrapping around a helmet and attachment point. A resettable three-digit combination supports keyless access, and the Lock and Hold format fastens down while locking. At 82 g, it is light to carry, and the included optional bracket can be used to carry it on a bicycle. It is presented for opportunist-theft deterrence.

Skip it if you need a heavy-duty locking structure rather than an opportunist-theft deterrent; Kewig CKB-4 has a double anti-theft cylinder structure.

This fits riders seeking a lightweight, resettable tie for helmet security at brief stops, with a 45 cm reach. Its stated opportunist-theft role is an important boundary for buyers needing a heavier-duty lock.

#9

9. ROCKBROS Retractable Lock 2-Pack

• Weight: 124 g
• Material: Zinc Alloy, Wirerope, PVC Coating
• Material Type: Zinc Alloy, Wirerope, PVC Coating

Best for: Combination-lock riders wanting two.

Why it ranks #9: The listing includes two lightweight four-digit locks with 4.6mm PVC-coated cable, but its stated product focus is cycling equipment.

Two lightweight ROCKBROS locks put a customizable four-digit combination at hand for securing helmets without carrying keys. Each has a 4.6 mm metal cable with PVC coating, offering a compact deterrent that also helps protect the helmet or nearby surfaces from scratches during everyday parking stops.

The four-digit code can be set by turning the lock collar according to the manual, making setup and routine locking key-free. The metal cable’s 4.6 mm diameter and PVC coating combine a physical tether with a surface-protecting layer, while the included pair lets riders keep a second lock available. At 124 g for the listed product, the lightweight format is easier to carry than a heavy-duty motorcycle lock, but remains a simple deterrent.

Skip it if you want a heavy-duty lock rather than a simple deterrent; Kewig’s 6061 aluminum lock has a double anti-theft cylinder structure.

Choose this pair for riders who value keyless operation and want two compact helmet tethers for routine stops. It is presented as a simple deterrent, so riders seeking a more substantial locking structure should consider that boundary.

#10

10. ROCKBROS Retractable Lock

• Material: Zinc Alloy, Wirerope, PVC Coating
• Material Type: Zinc Alloy, Wirerope, PVC Coating

Best for: Keyless riders wanting retractable cable.

Why it ranks #10: This two-piece, four-digit retractable cable set can secure motorcycle helmets, but its product listing primarily describes a bike lock.

A retractable cable pairs with a four-digit code on this ROCKBROS helmet lock, giving riders a key-free way to tether a helmet and draw the cable back when finished. The metal cable measures 0.18 inches in diameter and has PVC coating, combining a compact security tether with a surface-protecting layer.

The retractable format lets the cable extend for locking and return for storage, reducing the loose-cable handling of a fixed tether. A four-digit combination is set by following the manual, so routine access does not depend on carrying a key. The 0.18-inch metal diameter supplies the stated cable thickness, and PVC coating helps prevent scratches. The listing identifies two locks, making the set useful when a spare or second helmet tether is needed.

Skip it if you need a specified cable reach before purchase; MEETLOCKS MTP0001 lists a cable extending up to 1,000 mm.

A practical option for riders who want a retractable, keyless helmet tether and the convenience of two locks. Since no extended cable length is supplied, it is less suited to buyers whose attachment setup demands a confirmed reach.
