Harley-Davidson Helmet Lock

This universal helmet lock, designed in a carabiner style, secures your helmet, jacket, or bag against opportunistic theft. Compact enough to carry in your pocket, it fits handlebars or engine guards up to 1.5" (38mm) in diameter. It operates without keys—set your personal 4-digit code, thread the carabiner through your helmet’s D-ring, and lock it with the outward-opening mechanism. Crafted from aluminum and zinc alloy, the carabiner features a durable rubber coating to safeguard your bike’s finish.
