1. Brake-disc gap: Standard on all XENA models at 7mm.
2. Locking-pin size*: from 6mm (XZZ6) to 18mm (XN18) according to model.
3. Distance from locking-pin to back of disc-slot: From 42mm to 65mm according to model.

*Note: the pin can pass through ANY hole on the disc (red areas on diagram).

Our Fitment Chart is for general reference only. If your bike is not listed here, it is still very likely that there is a XENA lock that fits. However, note that motorcycle brake discs vary according to model year and geographic area. We highly recommend downloading and printing out our XENA Lockfitter template to get a clear idea of which XENA is right for your bike (see below). Prints standard A4. Cut out and align with edge of brake disc as per the instructions.
