Long Lasting Product

After trying several brands of chains about 4 years ago, started running the R1, and found out they outperformed any of the others that I had tried. Even on a 250 4-stroke ridden very hard on motocross tracks, the chains stretch very little and lasts for many hours of riding. I generally have to adjust only once or twice after first installing, and then it seems like I don't have to re-adjust forever.

Same chain on all my bikes

I and my boys race motocross, we all use a version of this chain and it has never failed to deliver on he track. I work at Motosport.com and I'm super picky about my parts and modifications. I would recommend this chain to any of our customers or my racing buddies.

Great Chain

I don't use x or o-ring chains on my dirt bikes, and in my opinion this is the best chain overall for price and durability.

Only chain I will buy. Outlasts the life of the sprockets every time. Easy to cut. Never had a problem.

Q: What is a wear life index on chains
Over 3 years ago
MotoSportExpert

A: The Renthal chains don’t have a wear life index, which is basically just an arbitrary number derived from comparing to a “standard” 100 link chain, it isn’t a very useful number.

Chain wear is best measured by using a chain tool and measuring the elongation or amount of “stretch” over 16 pins, each chain has a maximum allowable measurement before needing replacement and below is the information.

Here’s the length on the R1 520, 259mm or 10.197 inches.

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

A: 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.

A: 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.

Q: 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?
Over 4 years ago
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?
Chris
Over 4 years ago
A: 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.

A: 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.

Q: How many links
Over 8 years ago
I have a 08 crf250r how many links does the chain have on my bike?

A: 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.
Drewski

A: 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.

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

A: 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
DannyD303
Over 8 years ago
A: 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.

Q: Tuner sporcket kit
Over 9 years ago
i just bought a new sprocket kit and my front sporocet is a 12t and the rear is a 54t. the kit came with a chain, the chain is a renthal R1 420 gold chain of 120 links, will this chain fit on the new sprocket, will i have to take out links or add any links.

A: 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.

A: 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.

Q: 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?

A: 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!

Drewski

A: 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.

Q: 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

but still why is it not suitable for Enduro racing.

Expert MotoSport Staff
Over 9 years ago
A: 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.
