Kryptonite 1090 Evo Chain

The hexagonal shape of these 10mm hardened steel links is specifically designed to resist bolt cutters. Because the edges are harder to grip and cut through than traditional round steel, they provide a significant deterrent against common theft tools.

The 1090 length is generally sufficient for locking your frame and one wheel to a standard bike rack or pole. However, if you have a larger frame or prefer locking both wheels, you may want to measure your specific setup to ensure the chain has enough slack to wrap comfortably.

To keep the 5-disc cylinder operating smoothly, it is a good practice to lubricate the lock mechanism with a silicone-based spray once or twice a year. The included dust cover is excellent for keeping debris out, but regular maintenance ensures the key turns easily in all weather conditions.

Kryptonite offers a Key Safe Program where you can register your key number online immediately after purchase. If you lose your keys, you can order replacements directly through their program, which is much easier than trying to replace the lock entirely.

Yes, the hardened steel construction and high-security cylinder make this chain robust enough for motorcycles and scooters. It is a popular choice for securing smaller motorized vehicles, though you should always ensure the chain length allows you to secure the frame to a fixed object.
