The MotoSport.com Renthal Twin Ring Sprocket Kit includes ONE Steel Countershaft (Front) Sprocket, ONE TwinRing® Rear Sprocket, and your choice of ONE Premium 520 Drive Chain, each with the following features:

Sprockets / Chainwheels Included:

Renthal Front Sprocket:

When looking to replace your sprockets, Renthal sprockets are an easy choice because of their strength and inexpensive price tag.

  • Also known as "chainwheels", Renthal front sprockets are precision manufactured to withstand the rigors of Supercross, motocross, and enduro racing.
  • Renthal Front Sprockets are made out of 655M13 nickel-chrome-molybdenum alloy steel. What does that mean to you? Ultimate strength and hardness.
  • Self-cleaning mud grooves prevent the build-up of dirt.
  • Precision machining to extremely tight tolerances ensures that Renthal front sprockets are always within spec.

Renthal TwinRing® Rear Sprocket:

The TwinRing® Rear Sprocket is the longest lasting, most durable off-road sprocket you can buy today. Its unique design and hybrid construction was developed over a five year period.

  • A long lasting and durable hybrid material off-road sprocket made from an aluminum inner core and a steel outer ring.
  • Has a unique flat face design which keeps weight to a minimum and means the TwinRing is as narrow as a regular chainwheel.
  • Inner Ring is high strength ultra-light 7075 T6 aluminum; Outer Ring is an electroless nickel-coated steel.
  • Outer is expanded at 200°C and then fitted to inner, creating a permanent bond for the life of the sprocket.
  • Available for most major off-road brands and models in Silver and Black. Renthal also offers Orange for KTM, Red for Honda and Blue for Yamaha.

  • 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 X-ring chains: As X-ring chains are wider than standard roller chains, when fitting an X-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.

Note: Image is for reference ONLY, actual product will vary based on fitment and selection.

Excellent based on history with product

We always use Renthal bars and sprockets on our race bikes. We have never had issue with the full aluminum rear sprocket, but switched to the Twin Ring Rear Sprocket this time in an effort to improve on already excellent durability. I anticipate great results with the steel outer ring.

Outstanding durability

I love Renthal chain wheels. I bought this twin-ring set to increase durability. It replaced their T6 aluminum alloy product that I had run for a couple of seasons. And I can't believe how little wear there is on the all aluminum alloy wheel. Really fantastic. Twin-ring should outlast me.

Highest Quality, Longest Lasting

I have run Renthal chain & sprocket set ups on dozens of different off-road and road bikes over a 25 year racing, riding, testing and tuning career. At times I spend upwards of 100 days per year riding off road, and I ride a street bike in place of a car most days. I have built a number of race winning and championship wining machines over the years as well. Firstly, When you replace your chain and sprockets you should always do so as set. This ensures the best longevity and performance from your drivetrain. This is because the chain and sprockets wear together, and by replacing one component, but not the others, this accelerates wear for all the components, both new and old. In the case of these Renthal items, their high tensile strength chains and specialy machined hard anodized sprockets last longer (with proper lubrication and adjustment) than any other set up I have ever used over my very long riding-racing career. I reccomend Renthal full aluminum sprockets and non O-Ring R1 Works Chains for MX and sprint Racing. This is because in MX and sprint Racing these are the lightest, strongest components available, and therefore rob dthe least power from your drivetrain and provide the least possible unsprung wieght . This paticular set, with Renthal Works O- ring chain and Twin Ring Steel Teeth-Hard Anodized Aluminum inner is for a high use off road Endurance Set-up on a YZ450. For offroad and road race Endurance racing, long duration training rides, and all Streetbike applications, the Twin Ring is the way to go because it offers unmatched lightness combined with incredible durabilty and toughness. This YZ450 routinely sees 50 miles of sand, rocks and desert riding per fuel tank, and 100 miles per day is not uncommon. The twin ring set up will last for at least 100 hard run race-practice days and many, many hours. This is the set up I reccomend for recreational riders because the long life saves you a ton of money, and if properly adjusted and lubed will last most riders several seasons and will out last other aluminum chain sprocket combos by several times, all while wieghing a fraction of what other steel set ups wiegh, meaning you are not losing power by using aheavy steel sprocket drive line set up. It is important to note this set will be lubed after the chain and sprockets are warmed with Maxima Clear chain lube which is another important step and good tip. You should get into the habit of lubing your chain at the end of every ride when the chain and sprockets are nice and hot. This allows the lube to penatrate best, and then "set up" as driveline cools.This helps prevents most of your lube from flying off and ending up on your rear wheel, which is what happens when you lube cold right before you ride. Have fun and keep the rubber side down.

I want to preper my ktm 350sxf for desert race what sprocket size I should use ?
MotoSport Staff Expert
Over 6 months ago

For more top end you would want to go up 1 tooth in the front and/or down 1 or 2 teeth on the rear from stock gearing (14/50).

Chain Length?
Hey, I have an XR650R and my stock chain had 110 links with 14/47 gearing but Renthal only offers a 120 link chain with the 14/47 sprockets. Will the larger chain still work alright? Otherwise I found a Renthal street chain on Amazon with 110 links, should I go with the street chain?
Expert MotoSport Staff
Over 10 months ago
MotoSportExpert
The chain's come in 120 links to allow for the many different gearing options and bikes. You will just need to cut it down to fit. A chain breaker will push the pin out or you can grind the top of the pin off and the chain will pull apart. Just make sure not to cut it too short. http://www.motosport.com/dirtbike/BIKEMASTER-CHAIN-BREAKER?media=video

Cr 125 increase rear sprocket size?
my chain and sprockets need to be replaced. im thinking twin ring. i want to go from a 52 to a 53 im not worryied about the to speed of the bike. ive been on this bike for 8 years. do you think i will be able to feel a difference ?

MotoSportRyanT
You will likely only notice a small difference in top speed going just one tooth up on the rear sprocket. You will likely notice the bike accelerates to the top speed quicker but the overall top speed of the bike won't change drastically.

What sprokets should i run on my 09 kx250f?
What if I run a 14 and 50 tooth sprocket set instead of the 13 and 48 tooth set up?
MotoSport Staff
2 years ago Location: Portland, OR, USA
MotoSportExpert
Gearing is completely a personal preference. First i would ask whether you want more acceleration and to tighten the gears up, or do you want to spread the gears out and have them pull farther. By running a 14/50 you would slightly shorten the gearing up. This means you will gain a some acceleration but will need to shift sooner. The most common gear ratio for average tracks is a 13/49 combination on the 2009 KX250f.
1 year 7 months ago Location: San Diego County, CA
DirtBikeDocDave
Dewey, the 14 front has the effect of making the bikes gearing taller. In fact for each tooth you raise or lower on the front sprocket, it is aproximately equal to 3 tooth change of the rear sprocket. So, your 14 tooth sprocket in front is like dropping your rear sprocket 3 teeth. Since you want to run a 50 in the rear, which is 2 teeth shorter than stock, your net change from stock 13/48 will be a gearing set up that is slightly taller than stock. For a very detailed gearing setup guide I reccomemd a website called gearingcommander. Com. It is a non-profit site put together by bike engineers and allows you to see the results of any gearing and chain changes you may wish to make with a number of graphs and charts. Youcan plug your year make and model in and then enter differnt gear options in the data fields.

Sprocket hardware?
Are you able to use the stock hardware (bolts) to fasten the new sprocket to the hub?
MotoSport Staff
2 years 2 months ago Location: Portland, OR, USA
MotoSportExpert
Yes you can use the stock hardware to attach the sprocket to your hub. It is recommended to replace the hardware when changing sprockets though due to high stress they endure. There are after market sprocket bolt kits that are reasonably priced for a new set of hardware.

MotoSport Staff

MotoSportExpert
The X-ring chains really are the top of the line style chain. There are also Z-ring chains but is debatable as to which is better. O-ring chains with a single wide point of contact will tend to last a little longer but have much higher friction than the X-ring or Z-ring chains. One of the best X-ring chains out there is the DID ERV3. Incredibly high quality chain that you cant go wrong with.
1 year 7 months ago Location: San Diego County, CA
DirtBikeDocDave
My reccomendation for this type of high power setup is Renthal Twin ring, Renthal Steel Front, matched with Renthal Works O-Ring chain. These chain sprocket kits are all machined to work together, there are special chamfers on the matched Renthal chains and sprockets that deliver the best life. Make sure you replace chains and sprockets as a kit, and always lube them hot, right after your ride, so that the lube penetrates best and the cools off and "sets up" on your chains and sprockets. This will keep your lube from flying off when you ride, as happens when you lube the chain cold, right before you ride. If you did not remeber to lube after your last ride, no worries. Take the bike for a 10 minute ride to warm up the chain-sprockets, bring it back, lube it well, and then let it sit for 15 minutes or so.

unfortunately you must replace the whole sprocket once it wears out.

I think you are asking about the actual steel teeth on the rear sprocket. If so, I don't think it is sold separately. You can purchase the rear sprocket assembly separately without having to buy it in a kit that would include the chain and front sprocket. Hope this helps.

No you can't replace the outer ring when it wears out. Will last 5x longer then a aluminum sprocket.
