Kryptonite Keeper 5s Disc Lock – Yellow 5.5 mm Pin Compact Stapler-Style, Reminder Cable

The Kryptonite 000884 Keeper 5s Yellow Disc Lock is a compact stapler-style disc brake lock that secures motorcycles and scooters by blocking the rotor to deter roll-away theft.

Designed for riders who need a lightweight, easy-to-carry deterrent, the Keeper 5s uses a reinforced disc-style cylinder and a 5.5 mm hardened locking pin to anchor the lock through smaller brake-rotor holes. Its bright yellow finish improves visibility as a visual theft deterrent, and the included reminder cable helps prevent accidental attempts to ride off with the lock still engaged. The lock is built to be compact and portable while fitting many common rotor designs with up to 1.63 inches (41 mm) clearance for rotor insertion.

How does the Keeper 5s stop wheel roll-away and ride-away incidents?

The stapler-style design clamps across a brake rotor and physically prevents the wheel from rotating, making it difficult to push or ride the bike away. The design targets the rotor hole so it interferes directly with wheel movement rather than just attaching to a fork or frame.

• Stapler-style pin passes through rotor hole to lock wheel rotation.
• Dual reinforced disc-style cylinder increases resistance to tampering.
• 5.5 mm hardened pin diameter engineered for smaller rotor holes.
• Bright yellow finish acts as an additional visible deterrent.

Will this lock fit my motorcycle or scooter rotor?

The Keeper 5s fits many vehicles with smaller disc-rotor holes thanks to its 5.5 mm pin and allowance for up to 1.63 inches (41 mm) of rotor insertion. Check the diameter of your rotor hole and measure the distance across the rotor opening before purchasing to confirm compatibility.

• Pin diameter: 5.5 mm, suitable for small rotor holes.
• Maximum rotor insertion clearance: 1.63 inches (41 mm).
• Compact footprint fits under many seats or in small bags for transport.
• Reminder cable included to attach lock to bike when parked.

How easy is it to carry and use this disc lock every day?

Keeper 5s is intentionally compact and lightweight so riders can carry it on daily commutes without significant bulk. Operation is straightforward: align the stapler-style pin through the rotor hole and push to engage the lock, then attach the reminder cable to the handlebar or mirror.

• Small, stapler-style form factor stores easily in luggage or under seat.
• Simple push-in locking mechanism for quick application and removal.
• Lightweight construction minimizes added carry weight.
• Reminder cable reduces risk of leaving lock engaged when attempting to ride.

What security features does the Keeper 5s include?

While compact, the Keeper 5s integrates several security-focused details: a dual reinforced disc-style cylinder to resist forced entry and a hardened 5.5 mm pin to withstand cutting attempts better than softer alternatives. The lock’s visible color and solid construction act as both a physical barrier and a deterrent to opportunistic thieves.

• Dual reinforced high-security disc cylinder for improved pick resistance.
• Hardened 5.5 mm pin diameter for better cut resistance than basic pins.
• Bright yellow body increases visibility to deter casual theft attempts.
• Includes reminder cable to prevent accidental ride-offs with lock attached.
