KRASER 6Y Alarm Disc Lock — 6mm Heavy-Duty Motorcycle Brake Lock with 110dB Alarm, Weather-Resistant, 3 Keys

The KRASER 6Y is a heavy-duty 6mm disc brake lock with a 110 dB built-in alarm, weather-resistant housing, three keys, reminder cable, and accessories to secure motorcycles, scooters, e-bikes and mopeds.

Whether parked on the curb, in a garage, or at a rest stop, the KRASER 6Y Alarm Disc Lock combines a compact mechanical lock with an integrated electronic alarm and practical accessories so you can deter theft without bulky chains or anchors. Engineered for everyday use, it balances physical blocking of the rotor with a loud deterrent signal and features that resist impact and wet conditions.

How loud and responsive is the alarm when someone tampers with the bike?

The 110 dB alarm is designed to attract attention immediately when significant motion is detected. Improved electronics provide a short warning sequence before the full alarm triggers, giving owners a chance to disarm it if it was activated accidentally.

• 110 dB siren for strong audible deterrence
• Motion sensor plus pre-alarm 3 beeps for false-alarm reduction
• Rapid trigger response to impact and vibration

Will this lock fit my motorcycle, scooter or e-bike brake disc?

The KRASER 6Y uses a 6 mm locking pin designed to fit most common brake disc holes and mounting slots, making it widely compatible across bikes. Its compact profile locks simply by pushing the shackle into place without complex alignment steps.

• 6 mm universal shackle for standard disc holes
• Simple push-to-lock operation for quick use
• Lightweight and compact for easy storage in the included pouch

How durable is the lock in wet or rough conditions?

The housing is built to resist impact and corrosion, and the alarm electronics are rated to handle exposure to rain so the device remains functional outdoors. Reinforced construction combined with rust-resistant finishes helps the lock keep working season after season.

• Anti-impact casing to resist blunt force attempts
• Weather-resistant electronics to handle rain and moisture
• Anti-rust exterior materials for long-term durability

What accessories come with the KRASER 6Y and how do they help everyday use?

The 6Y arrives as a ready-to-use kit so you won’t need extra parts to get started: three metal keys, a reminder cable to prevent riding off with the lock engaged, spare batteries, a textile storage pouch, and an Allen key for maintenance. These extras remove friction from daily locking routines and lower the risk of accidental damage.

• Three keys (plus alternatives included by the seller) for convenience and spares
• Reminder cable to attach to handlebars and avoid riding away with the lock on
• Textile pouch and Allen key for storage and small adjustments
• Spare battery set to keep the alarm active without immediate replacements

Who is this for? Riders who want a compact, highly audible theft deterrent that’s simple to use and suitable for everyday parking situations will appreciate the KRASER 6Y. It’s especially useful for motorcyclists, scooter and e-bike owners who need quick, portable protection with weather resistance and practical accessories — ideal for commuters, city riders, and anyone looking for extra peace of mind without heavy anchoring systems.
