The OnGuard Smart Alarm Disc Lock delivers powerful motorcycle security by combining a hardened 10 mm carbide-reinforced locking pin with a piercing 120 dB alarm that activates instantly from motion, shock, or tampering. Its weather-sealed, high-visibility yellow body deters thieves while protecting internal electronics from dust, rain, and freezing conditions. Compact for daily carry yet rugged enough for harsh environments, it includes a reminder cable and padded storage case, making it an essential defense against roll-away or drive-off theft attempts.
