    The 520EXW Gold XW-RING Chain’s metal components are made from a specialized high carbon steel alloy that is shot peened, heat treated, and pre-stretched to create a chain that lasts for an incredibly long time. So tough in fact that it will outlast other 520 chains by 10%. Factors that make the EXW such a long wearing chain also include the anti-corrosion, gold tinted surface treatment and the unique design of the EXW’s O-ring, which has an additional sealing surface to retain more lubricant. With an 8,500 pound tensile strength, RK has made this chain strong enough for any off-road application that has a 750cc displacement or less.

  • Sealed ring design
  • Includes clip type master link
  • Recommended 750cc limit
  • 8,500 pound tensile strength
  • Chain is shoot peened, pre-stressed, and heat treated
  • 10% longer wearing than other 520 chains
  • Chain material is high carbon alloy steel

Great product

Comments On Aug 23, 2015:Very nice looking chain. Been riding with it for a while and shows no sign of wear or stretching. May be a little pricey but look at the price of other high quality chains, and this one is tier 1.

Buy once cry once

Comments On Feb 14, 2015:Do your self a favor and buy a quality chain so you don't end up spending more in the long run. Rk x-ring in my opinion is the best chain on the market.

Nice chain

Comments On Jan 27, 2015:I've used RK chains in the past and have never been disappointed. No problems with this one so far. Initially stretched more than I expected, but after that it's been great.

Awesome chain

Comments On Dec 29, 2014:Put it on my quad and didn't have to tighten it for 3, 5 hour rides. I would by this chain again and again. Its a little more expensive but you get what you pay for.

I got less time out of it than I expected.

Comments On Dec 27, 2014:I got turned onto these by the people at bestdualsportbikesdotcom for the KTM EXC's. I got about 20 hours on the chain before I noticed a change of shape on the rear sprocket teeth. I washed it with ordinary auto parts store engine degreaser and oiled it with PJ1 after almost every wash. I'll try primary drive's X-ring next time and see if it's worth saving $20.

Great durable chain!

Comments On Dec 01, 2014:I have had this chain on for a year and it hasn't had to be adjusted once yet. The sprockets are still looking new also. Not sure if it's even broken in yet, it's still feeling pretty stiff. I ride this machine all the time though. Should last a very long time if you take care of it.
