Excellent chain at an even better price. Been using Sunstar chains for years and have never had one complaint.
Most people don't know that the OEM chain on their bike is most likely a Sunstar !

Average chain

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.
