Mounted on a 2002 yz250. After 4 rides its stretching fairly quick, even after the initial stretch you get with most chains. Good for if your on a budget but I would recommend a higher quality chain for next time.
For a quality non-sealed O.E.M. replacement level chain, Sunstar offers the 520HDN (HDN = Heavy Duty Non-sealed). This cost effective replacement chain offers great performance and durability at a great price point. This chain is recommended for any motorcycle up to 250cc and is available in pre-cut lengths. It uses a clip-type master link and provides great strength with a 7,850-pound rating.
