520 XSO Performance RX-Ring Drive Chain

I am very pleased with this chain. I went on a 4 hour ride and the chain did not stretch and did not need to be adjusted for the second ride (Used on CR500). It comes with a Rivet master link.

Great Chain!

Bought this for my Kawasaki Versys used the 114 link chain with stock front sunstar 15 tooth and a rear sunstar 44 tooth in the back. What a difference in RPM's and the smoothness of the bike! The chain came with a press on clip so you will have to get the clip connecting link Part # 119997 and its a pain to get on with out a link pressing tool. I used a small C Clamp and pressed the sides of the links together to get the clip on.! I will order that tool next time!

Great chain

Chain had excellent fit and finish. Anyone needing a rivet link, mine came with it, not the clip type as stated.
