Kryptonite Keeper 712 Chain Lock
The Kryptonite Keeper 712 combines a 7mm hardened steel chain with four-sided links to resist cutting and leverage attacks. It features a patented locking system, including a high-security disc-style cylinder that deters picking and drilling. A hardened end link securely connects the chain to a deadbolt, reducing weak points. A protective rubber coating helps prevent scratches on the bike, while a weather-resistant nylon sleeve shields the chain from the elements.
In practice, this lock balances portability with robust defense. The 4-foot length is suitable for locking a motorcycle to posts, racks, or fixed structures without excessive weight. The design emphasizes compatibility with standard U-locks and other securing points found around residential garages and commercial lots. For riders who value reliable security without carrying super-heavy gear, this Kryptonite option offers a well-rounded solution.
KOHLBURG Heavy-Duty Chain Lock
KOHLBURG’s 4-foot chain lock is designed for maximum security, rated at the top DIAMOND level by an insurance testing institute and a Sold Secure certification. The 10-pound heavy chain uses specially hardened steel to resist cutting and leverage. The high-security, pick-resistant cylinder helps prevent theft via lock-picking. A long chain aids in securing multiple points or wrapping around sturdy fixtures, making it a strong choice for motorcycles, scooters, and other valuable two-wheelers.
The lock’s extra-long chain length provides flexibility in crowded parking or street-side scenarios. The combination of certified protection and durable construction makes KOHLBURG a preferred option for riders who park in busy urban zones or roam between destinations. While heavier than compact options, this lock trades weight for significant resistance to theft attempts.
Titanker Motorcycle Chain Lock With U Lock
This Titanker set combines a 4-foot chain with a 14mm thick U-lock, delivering dual-layer security. The 12mm square chain and 14mm U-lock are designed to resist cutting and lever attacks. The lock cylinder uses zinc alloy construction with two brass keys to simplify access, and a nylon sleeve protects the chain from scratches. The ergonomic design and included keys make this a practical option for riders who want flexible mounting options and strong deterrence against theft.
With a combined weight around the mid-range for chain-and-U configurations, this set is suitable for motorcycles, mopeds, and larger electric bikes. The dual approach—chain plus U-lock—offers versatility for securing to posts, rails, or fixed outdoor structures. Regular lubrication is recommended to maintain smooth operation and extend the lock’s service life.
Grentay 5.18Feet Chain Lock With U-Lock
The Grentay setup features a 5.18-foot chain crafted from 3T manganese steel, paired with a 17.5mm U-lock. The chain’s thickness and steel type are designed to resist shearing, prying, and cutting. The included U-lock provides a robust second line of defense with a complex cylinder and reinforced body. A nylon sleeve protects the chain from scratches and weather exposure, making it a practical all-weather option for bikes, scooters, and light-duty motorcycles.
Designed for families or riders with longer parking needs, the Grentay system supports securing multiple bikes or other gear. The dual-layer structure emphasizes long-term security in areas with higher theft risk and where attackers may attempt to breach through multiple points of entry.
WARLION Heavy Duty Security Chain
The WARLION chain measures 10 feet in length with a 3/8 inch (9mm) thickness. This extended length allows secure anchoring to larger fixed objects and adds flexibility for locking multiple items. The chain is made from premium case-hardened steel and includes a cinch ring design to ensure a tight fit when extended. The chain is coated to resist rust and corrosion, and a detachable nylon sleeve protects against scratches and weather damage. This is a practical choice for riders who routinely park in public lots or need to secure motorcycles in shared spaces.
While heavier than shorter options, the WARLION chain prioritizes length and raw resistance. The cinch ring feature helps achieve maximum security without compromising ease of use, making it suitable for long-term outdoor storage or frequent parking in high-theft areas. The chain’s construction aims to deter high-risk theft attempts through reinforced materials and thoughtful design features.
Buying Guide
Key considerations when selecting a motorcycle lock chain include chain thickness, length, lock mechanism, and protective features. Thicker chains (around 12–17mm) provide stronger resistance to cutting and leverage, but add weight. Longer chains (4–10 feet) offer more mounting options and the ability to secure multiple points, yet may be less portable. A robust locking mechanism with pick resistance increases security, while a durable nylon sleeve or rubber coating minimizes scratches on paint and chrome. Weather resistance is essential for outdoor storage.
Security levels and certifications help gauge reliability. Look for Sold Secure or DIAMOND ratings and independent testing results. A dual-system approach, such as pairing a heavy chain with a strong U-lock, often yields better protection than a single locking method. For urban riders, ease of use and key management matter; models with multiple keys and user-friendly cylinders reduce lockouts. Budget should be weighed against the risk environment, parking habits, and the value of the motorcycle.
Maintenance tips include regular lubrication of the keyhole and moving parts, cleaning away moisture, and inspecting the chain sleeve for wear. If the lock is used in damp or salty environments, rinse and dry the hardware to prevent rust. Consider pairing a chain lock with a secondary security device, such as a disc lock or wheel lock, for enhanced protection in high-theft neighborhoods.
