The OnGuard Boxer X4 Disc Lock (Yellow) delivers robust security and unmistakable visibility for motorcycles, scooters, and e-bikes. Its 14 mm hardened-steel shackle resists cutting, prying, and impact, while the X4P Quattro Bolt System secures the shackle on four sides for unmatched holding power. A Z-Cylinder core prevents drilling and picking, and the vivid yellow finish acts as a clear visual deterrent against theft. Compact and easy to use, the Boxer X4 includes a disc-reminder cable to prevent accidental ride-offs and a convenient carrying case for storage. Engineered for durability, it provides pro-level protection in a portable size—ideal for daily commuters and long-term parking alike.
