10 Best Motorcycle Disc Locks 2026 in the United States

The Kryptonite New York Fahgettaboudit 1415 Chain with New York Disc Lock is a robust anti-theft solution designed for bicycles, e-bikes, scooters, motorcycles, and ATVs/UTVs. Its standout feature is the 14mm six-sided chain links made from 3t hardened manganese steel, offering exceptional strength and resistance to cutting or breaking. The lock mechanism features a 15mm steel shackle and double deadbolt locking system, providing extensive holding power and added security.

The chain is covered with a durable nylon sleeve to prevent scratches on your vehicle and includes hook-and-loop fasteners to keep it in place, enhancing its usability and protection against the elements. The weather-resistant feature ensures the lock performs well even in harsh conditions. However, the product does not include an alarm feature, which could be a downside for those seeking an additional layer of security.

The chain and lock are quite heavy, weighing over 15 pounds, which might impact portability for some users. Despite this, the high-security features and durable build make it a reliable choice for those prioritizing maximum security over convenience. The lock is keyed, and it comes with three keys, ensuring you have spares. This product is well-suited for individuals who need to secure their high-value vehicles and can manage the weight and absence of an alarm.

The YOHOOLYO Alarm Disc Lock is a solid choice for motorcyclists and scooter riders looking for reliable anti-theft protection. Made from forged stainless steel, it offers good durability and resistance to tampering. The locking mechanism is straightforward with a one-press operation, making it easy to engage quickly. Its 7mm pin size fits a wide range of vehicles with disc brakes up to 6mm thick, so it works well for many motorcycles, scooters, and bicycles.

One of its standout features is the loud 110 dB alarm that activates automatically when it senses vibration or shock, which can deter thieves effectively. The lock is waterproof, so it holds up well in rainy weather without rusting—a key point for outdoor use. It also includes two keys, a 5-foot reminder cable to prevent riding off with the lock still attached, and a carry pouch for convenience.

On the downside, it requires 12 LR44 batteries (all included), which may need replacing over time. It does not come with a remote control, so alarm management is manual. Also, the lock’s size and weight (about 12 ounces) make it fairly portable but not the lightest option available.

A standout feature is its smart alarm system with a two-step warning process: a pre-alarm activates with initial movement, followed by a loud 100 dB alarm if the movement continues, effectively deterring thieves. The lock also includes a transport mode that uses a brake disc detection system to prevent false alarms during legitimate bike movement, and LED indicators provide information on alarm status and battery life, adding convenience.

Weighing just under 2 pounds and compact in size, it is reasonably portable for daily use or travel. The use of hardened steel and solid construction suggests it can handle typical outdoor conditions well. The lock requires 2 AAA batteries, which are included.
