Just installed this chain. Can’t speak for durability but fit was perfect. Love that Rocky Mountain takes care of selecting the right size for your machine.

I bought this chain and new sprockets for our kx 65 , a 13 tooth on the front and a 48 tooth on the rear , the chain is not long enough , do I send it back ? Is there a loner one ?
A shopper on Sep 28, 2019
BEST ANSWER: If you would like to set up a return for this chain, please call 1-800-336-5437 or email [email protected] To order the correct one, you will need to remove your machine profile and select the correct amount of links you need.
Trying to order a chain for Honda crf50f I have the part number 40530-GEL-701 but your site is asking me 420x100, 420x101,102,103 ect.. can some one help me out? I don't know which one I need..thanks
A shopper on Aug 14, 2017
BEST ANSWER: The part number you have is for the stock OEM chain which we do carry. However this chain is an after market chain so it will need to know how many links you would need. I would be happy to help you with this. What year is your machine? Also did you mean to say you have the crf150f? Lastly, do you still have your stock sprockets on this?
