  • Fitment

Renthal's R1 Works Chain is a high-strength non O-ring chain with excellent impact load resistance designed specifically to withstand the stress found in off-road applications. This chain is the choice where a combination of high strength, light weight and maximum power transfer are important considerations.

  • Shot-peened alloy steel side plates for high tensile strength and maximum impact load resistance.
  • Chamfered inner links to reduce the chance of chain derailment.
  • Extended bushings to reduce friction between outer and inner link plates, maximizing power output.
  • Chromized bearing pins for excellent resistance to wear.
  • Gold color side plates help prevent corrosion.
  • Most perfectly matched chain for Renthal sprockets allowing maximum power at the rear wheel. This also extends the life of both the chain and sprockets.
  • Average tensile strength of 7,644 pounds.
  • Wear life index: 300.
  • Maximum displacement (2-stroke / 4-stroke / Trials): 250cc / 450cc / 400cc.
  • Weight (per 100 links): 2.13 pounds.
  • Each chain includes master link and a pair of latex gloves for mess free installation.
  • Note: Non-sealed chains require more regular maintenance than sealed (O-ring, X-ring) versions and are mainly recommended for off-road use.

Upgrade from stock

Needed to replace an old O-ring chain that the previous owner had installed on a bike I bought. So far great chain. Minimal drag, looks good and durable. Make sure you have a chain breaker to properly fit.

Motosport is hands down the best!

Yes this chain is the deal, trust me, I race and Im an old man and I have used them all and hands down a Renthal R1 is superb. Got to say Motosport takes care of their customers in a timely fashion. I couldn't be any more impressed and this is my one stop shop!!

Good chain

its a drive chain. Went on personal brand preference with this. Could have saved about twenty bucks by getting a standard gray or black chain in another brand. but I have to admit that the gold chain just looks awesome.

Give and Take with the R1

I have ran the Renthal R1 chain on my 250's, 250F's, and 450's since 2000. I have had some R1 chains last a year and a half and others last about 6 races. Out of the 20 something R1's I've used over the years, I have only had about 4 "duds" I didn't bother trying to get a hold of Renthal or the place I purchased the "dud" chains from. I just sucked it up and purchased another one.

What is the chain slack spec for a 1986 yz125, and the rear axil torque?

Unfortunately, I would not have the specific service specifications for your 1986 Yamaha YZ125. I would have to recommend you refer to the service manual for your bike or contact your nearest Yamaha Motorcycle Dealership for that information.

No clue on the specs but slack is usually 2-21/2 inches from top of swingarm in the middle of the chain. Or 2 or 3 fingers space with fingers vertical depending on riding conditions. For muddy conditions I always adjust the chain slightly more loose. As far as rear axle torque, prob somewhere between 50 and 65 lbs/ft. For exact specs you would need the bike specific manual for both specs. You might also try and contact customer service or tech department. They may be able to help.

I recently just bought this chain, and while I was breaking the links I accidentally broke off too many links. Am I able to push the pin back in?
Broke off too many links, even with the tire as far forward as it can go. Can I push the pin back in or did I ruin the chain?

It is not recommended to re-add links to your chain as you would need to use 2 masterlinks and doing so will significantly weaken the chains tensile strength. You would need a rivet style masterlink and a chain press to add links back onto the chain, but even with the link riveted in, the chain would still be weaker and may not last as long.

I did the exact same thing! I took the chain to a local shop and they said yes it's possible but they wouldn't do it because of liability issues. The cheapest chain press they had was $160. I had no choice but to buy a new chain, with an unused one still in my hand. I was pretty mad. Don't try to push the pin back in, it's not worth it when that pin slips back out and you end up in the hospital. Take a close look at those pins and you will see that they are slightly mushroomed on each end to hold them in place. If you try to push it back in you won't be able to re-create that factory made mushroom. Bite the bullet and buy a new chain.

How many links?
I have a 08 crf250r how many links does the chain have on my bike?

It really depends on the gearing you are running. The stock length should be 114 links, but you may have to count the links if you've changed your gearing any to get a solid answer.

the chain you're buying has 120, and that will fit your bike. if your sing arm is too short its easy to take off a couple links.

Since its corrosion resistance, does this mean it can never rust?

This chain can rust if not lubricated. This is a steel chain, not an O-ring chain. These chains will stretch, they are lighter than an O-ring but will not last as long as an O-ring chain. If you are racing at a pro level the steel chain is a good choice if you race for fun and like to ride, get the O-ring

I can give you a definitive answer but I believe resistant mean exactly that, it resists rust. As long as you keep some sort of lubrication oil on the chain you should never get more than minimal surface rust.

you will most likely need to take out links but since I don't know what bike you are putting them on it's hard to tell you for sure.

if your using the same size sprockets that are already on your bike, just count the links in your old chain and use the same amount for your new one. if your old sprockets have different amounts of teeth than your new ones, you may need to cut it down, or get a bigger chain.

Is renthal reliable?
my friend told me renthal sucks i no thats true with bars and sprokets when your just trail riding but are their chains any good?
MotoSport Staff
Over 6 years ago Location: P+RTLAND
Drewski
Personally I've always had good luck with all my Renthal products. It's all about finding what works best for the type of riding you are doing. Since they make their sprockets out of aluminum and the R1 chain you are looking at is a motocross/supercross style chain, it's probably not going to be the best set up for heavy trail riding or dune riding. You may want to look into a chain more suitable for trails.

I was brought up to pick good friends who dont lie to me. And it appears that is exactly what your friend is doing to YOU!!! Renthal is a great brand for everything they make. shoot i even use their brake pads. the truth is that when you buy something that says Renthal on it, it IS going to be very high quality and very durable. Sprockets, bars, brake pads, and yes even chains. you name it, you cant go wrong with Renthal. Good Luck!

If my stock chain is 92 links, am i okay getting 120 links and taking some out. I am increasing the rear sprocket from 40 to 41 teeth on my 2002 rapt?

well there's no reason why you could use it for any type of riding. It's a durability issue, and when you are riding in all types of conditions from wet to dry you'll be replacing a non-oring chain very often.
