Overview of RK 520 XSO Performance RX-Ring Drive Chain - 520XSO120

  • RK racing chains have been the overwhelming choice of World Championship Teams for the past two decades!
  • They have benefited from their long-term OEM relationships with the major Japanese motorcycle manufacturers; RK has supplied original chains and chains for racing
  • All high-quality RK chains are made in Japan except the standard RKM series, which are from Malaysia
  • All RK chains feature quad-staked pin riveting, solid rollers and solid bushings, except the RKM and standard series, which have two-point riveting and curled bushings
  • They are all pre-stressed and pre-stretched for better performance with fewer adjustments


  • PERFORMANCE RX-RING SEALED CHAINS (XSO)
  • Lubricated with specially-formulated, vacuum-injected U-grease locked in at 4 sealing points by tough rubber X-rings

  • High tensile strength ensures reliable performance
  • Max. Engine Size: 750cc

Great Chain!

October 19, 2013

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!

I would recommend this item to a friend.

Great chain

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

I would recommend this item to a friend.
