Good Chain
Good chain for the little bikes. Last long on my kids XR70 but will stretch a bit if my big old butt gets on their little bikes.

Great Mini Chain
I own a 1970 Honda QA50. Aftermarket parts are sometimes had to find. The chain was really old and wore out. This chain fit perfect and I didn't even need to cut it.

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?
