The MRD7 design minimizes friction while providing good resistance to tension and abrasion, suited for motocross demands. The aluminum sprocket lightens the assembly to improve the responsiveness of the rolling chassis without compromising strength against impacts. Regular inspection and maintenance (tension, lubrication) are recommended to preserve longevity and performance on the track.
