Cheap chain
I bought this chain around 6 months ago, . It's stretches every ride on our 65sx. After only 11 hours of riding it has lots of slop in the links and I am replacing it with something else.

Questions
What size of chain do I put on a 2008 kx 65? I bought a 420 x 110. It doesn't fit.
Always check with your bike manufacturer for the correct size chain for your bike.
