Lock Works Guardian GR100 Orange

Guardian GR100 is the choice primarily for European motorcycle brands with 100 mm bolt spacing, such as BMW, Ducati, KTM, Triumph, and more. This Guardian seamlessly matches the precision engineering of European superbikes, nakeds, and adventure bikes. The GR100 combines your motorcycle's sporty look with unparalleled ease of use: permanently mounted, locked in 5 seconds, and complete wheel immobilisation without risk of brake disc damage. For the European rider who expects convenience and premium quality.


Guardian GR100 is specifically designed for radial brake calipers with a 100 mm centre-to-centre bolt distance on the right 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.
