Lock Works Guardian GL80 Black

The Lock Works Guardian GL80 is specifically designed for lighter motorcycles and scooters up to 300cc. With a compact 80 mm bolt spacing, this Guardian fits perfectly on radial brake calipers of engines with smaller displacement. Despite its compact size, the GL80 offers the same premium security: ART4-certified, lifetime warranty, and complete wheel immobilisation without play.


The Guardian GL80 is specifically designed for radial brake calipers with a 80 mm centre-to-centre bolt distance on the left side. Using the included spacers, you can precisely adjust the fit to your brake caliper, ensuring the wheel is completely locked without any play. The mat black finish gives your motorcycle a sleek, premium look that perfectly complements modern bikes.
