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.

I have a 2006 Honda TRX 300 EX and one of the links broke then bent will this be a good replacement and will it need to be shortened or can I just replace the broken link

Yes, the chain would need to be cut to fit your specific gearing on your 300EX. You can not buy individual links. Feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
