## Customer Reviews

### ⭐⭐⭐ 







  
  
    Chain Length
  

*by Z***Y on Reviewed in the United States on April 12, 2019*

The only reason I am giving this chain and sprocket set a 3 star review is for fitmeant on my YZ85. I would imagine on a small wheel 85 the chain supplied in the kit would fit; however, on a big wheel YZ85 (16” rear wheel) the chain is about 1 link too short. The aluminum rear sprocket is great with an awesome fit and finish (is it CNC milled from a billet).

I didn't need to size it. It fits perfectly. Buy it.
