Installing a chain kit involves the simultaneous replacement of the sprocket and the crown to ensure even wear. To maintain longevity, regular lubrication and periodic checks of lateral play are recommended. This kit is suitable for road use and roadsters such as the KTM 640 Supermoto LC4 (example of compatibility); however, please check the references and gearing ratio before ordering to ensure proper fitment on your model.

Practical Tip: Replace the sprocket, crown, and chain in one operation to avoid premature wear and maintain the tension recommended by the manufacturer during installation.
