The versatile and super-strong XN10, in keeping with the complete line of XENA's high-performance XN series locks, is designed to fit right in with the finest motorcycle kit. High nickel-content stainless-steel construction, piercing alarm and polished good looks make the XN10 a remarkably effective way to protect your motorbike. The double-locking hardened-steel 10mm pin is carbide-reinforced to give would-be thieves a long night. Shock & motion sensors linked to a sophisticated microprocessor trigger a 110 dB alarm. The unit is self-arming, with no on-off switch, and re-sets automatically to armed mode within 15 seconds if the attack stops.
