Designed to withstand the demands of challenging environments, this chain is suitable for quad, urban, motocross, and roadster uses. It is particularly well-suited for powerful and versatile motorcycles — examples include models like the YAMAHA YZ 450 F (2026), the SUZUKI RM-Z 450 (2026), or the HUSQVARNA FE 501 (2025) — subject to verification of the number of links and transmission setup.

For optimal longevity: regular tension checks, appropriate lubrication, and inspection of the links and sprocket. The gold finish also adds a polished look to your transmission while facilitating visual wear detection.
