Description Item #REN001E

Renthal's R3-2 O-ring Chain is a high-strength sealed-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications where an O-ring chain is desired. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations. The O-rings help extend chain life by retaining the special vacuum-injected grease near the critical pin area. Chain comes pre-stretched to shorten break-in period.

  • Nitrile O-rings extend chain life by retaining special vacuum-injected grease inside the chain joint.
  • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
  • High-carbon alloy steel bearing pins for excellent resistance to wear.
  • Gold colored side plates help prevent corrosion.
  • Pre-stretched to enhance performance of the chain.
  • Available in 520 pitch only.
  • Average tensile strength of 7,644 pounds.
  • Wear life index: 750.
  • Maximum displacement (street / off-road): N/A / 500cc.
  • Weight (per 100 links): 3.36 pounds.
  • Each chain includes a pair of latex gloves for mess free installation.
  • Note: The Renthal R3-2 chain is supplied with both an easy-fit split master link and a superior solid-pin rivet master link which matches the durability of the chain.

Note for installing O-ring chains: As O-ring chains are wider than standard roller chains, when fitting an O-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.

Awewome Chain

I have this chain on all of my bikes. I have put 36 hrs on my trail bike and have only adjusted the chain twice. It is a little on the heavy side, but for novice/amateur racing it doesn't bother me. Definitely worth the money spent!

Poor durability

ive been riding and servicing motorcycles for 45 years. I installed this chain in 2012 and after just 3200 miles of street riding it has failed, its been regularly adjusted and lubed with pj1, but this summer I noticed rust on the links and upon closer inspection found some of the orings mia and pins corroded, chain has worn rapidly and failed. its evident something in their production methods has changed and not for the better.

Renthal chain

This is the best chain i have ever bought. I have ridden my yz450f really hard for about 25hrs and i havent had to adjust the chain at all. The chain came with 2 master links which is very helpful. I will only buy Renthal chains.

Solid chain

Seems to be a solid chain. Time will tell how much it stretches. Surface clean up and warm up and PJ lube will make it live.

Great replacement chain.

Its a great chain that works great. I bought it as a replacement because the one I was previously using was getting pretty bad. I wouldn't recommend it to replace a functional chain but renthal is usually delivers a good product and I can't really complain about it. The gold color is a nice touch as well.

Awesome performance

I bought this chain for my 89 banshee. Installed with the proper tools with ease. I rode the sand for three days without hardly any wear showing. I would have ran it some more but blew a motor :-(

Renthal 520 R3 O-Ring Chain

Such a hard wearing chain you really can't go wrong! We installed with a renthal front sprocket, supersprox steel rear and only had to adjust once in the first hour of riding. After that its maintained it integrity perfectly...60hrs of abusive sand riding on our rmz250 and looks good to go another 60!

BUY THIS CHAIN!!!

This is one of the toughest and durable chains on the market. No lie I still have this chain on my yz250f from when i put it on 2 summers ago to this day after many practice rides and about 10 hare scrambles, 2 of which were nothing but mud and slop. At about this point it has a little stretch in it but ill never change chains again. Thanks renthal!!!!!!

Is a spacer required when installing this chain on a 2004 Yamaha YZ250 (to provide adequate clearance between the chain and case)?

A: No. The only bikes that really have issues with clearance is the CRF 450/250 bikes with O X or Z ring chains if they are not made thin.

Does a crf250r need a front sprocket spacer with this chain? Or does it fit without one? I know on some bikes the chain will grind on the case due to it being a wider chain

Q: No clip style master link?

After reading a couple of the questions about this chain, it appears as though it does not come with a clip style master link. I have purchased 2 of these R3 chains before and each time the chains have included both the clip and rivet style master links. Have they changed the product to only include the rivet style?
