Kryptonite EV4 Disc Lock

The Premium Pack bundles the EV4 disc lock with a convenient carry case and a bright reminder cord. The cord is designed to loop around your handlebar, serving as a visual cue so you don't accidentally ride off with the lock still attached.

The shackle is 14mm thick, so you should measure the holes in your brake rotor before purchasing. While it is designed to fit most standard motorcycle and scooter rotors, it is best to ensure your specific bike has enough clearance for a shackle of this diameter.

The oval crossbar design is engineered to be more resistant to leverage attacks compared to traditional round bars. By changing the geometry, it makes it significantly harder for thieves to use tools like jacks or pry bars to force the lock open.

Yes, one of the three included keys features a high-intensity bulb that makes it easy to find and operate the keyhole in low-light conditions. It is a practical addition for parking in unlit garages or at night.

To keep the mechanism operating smoothly, it is a good idea to occasionally lubricate the cylinder with a silicone-based spray. Additionally, the sliding dust cover should be kept closed when not in use to prevent dirt and debris from entering the keyway.
