The HDS chain combined with XS-Ring seals aims to provide increased resistance to stress while facilitating maintenance. The aluminum sprocket, designated as "ultra-light," helps reduce peripheral mass compared to a steel sprocket, without altering the original architecture of the transmission.
Standard mounting on 12-tooth sprocket and 50-tooth sprocket. Before each ride, check tension and lubrication: regular maintenance prolongs the lifespan of your transmission and ensures more consistent performance on muddy or sandy terrains.
