Details

    Renthal Ultralight Rear Sprockets start their lives off by getting CNC machined from 7075 T-6 aluminum, an alloy that is prized for its strength and wear resistance. A near perfect material for sprockets. The alloy is light weight, and with Renthal’s drilled patterns, the Ultralight weighs up to 66 percent less than comparable steel sprockets while retaining a comparable lifespan. The material isn’t the only thing that promotes longevity. Self-cleaning cuts are machined into each chain groove to clear away mud and debris from sensitive wearing surfaces, so both the sprocket and chain are kept clean of abrasive particles. There’s almost no downside to putting a Renthal Rear Sprocket on your motorcycle or ATV.

    Specs:
  • Replacement aluminum rear drive sprocket
  • 66% lighter than comparable steel sprockets
  • Comparable lifespan to much heavier sprockets
  • 7075 T-6 aluminum alloy
  • Self-cleaning chain grooves
  • Fits OEM bolt mounts
  • Multiple colors available

Renthal Sprocket
Have run renthal sprockets for a long time, from 175hp superbikes to dirtbikes. They are extremely light, they were pretty good for aluminum and look great. Sprockets are always a trade off of durability and weight. Usually less rotating mass and less unsprung weight is a good thing! They are a great sprocket with good looks and performance to back it up.

Looks great - performs even better
I am rebuilding an old YZ and the rear sprocket was missing teeth and shark finned so bad it would barely hold a chain - straight to Rocky Mountain ATV I go and after searching through dozens of options, I settled on the Blue Renthal rear sprocket. Fit and finish are top notch (as expected from anything Renthal). Looks great on the old machine and works even better!

Bought to add some color to my bike, as if it wasn't blue enough. Easy to install and took twenty or so minutes to install. Remember to use that loctite!

Does the sprocket come with bolts to install?
A shopper on Dec 20, 2016
BEST ANSWER: Of all the Renthal sprockets I've ordered over the years They have never come with a bolt kit. I have purchased bolt kits separately in Titanium, steel and stainless from RMATV though.
are the sprockets stamped with how many teeth it has?
A shopper on Feb 7, 2017
BEST ANSWER: Yes, they do stamp their sprockets with the number of teeth. It's out towards the edge of the sprocket
How much does this weigh?
SCOTT C on Jul 10, 2017
BEST ANSWER: Extremely light, about as heavy as a piece of cardboard the size of the sprocket folded over onto itself to give you a more real world answer.
What will give my 07 crf150r small wheel more power? I want more power in lower gears and out of turns what would you recommend?
A shopper on May 21, 2017
BEST ANSWER: The only way to get "more power" to the rear wheels is more engine HP, or less resistance in the driveline. Adding a rear sprocket with a higher tooth count can shift your gear ratio around to where it better suits what you need. Think of how a 10 speed bicycle works and you'll more readily understand. Gearing doesn't add power, it just moves it around so can use it more efficiently.
If the 2009 YZ 85 has only 4 sprocket bolts holes why does it say that sprockets that have six holes fit it?
Sam B on Oct 13, 2017
BEST ANSWER: Manufacturers mostly will make it to fit multiple bike's.
I would really like to get a blue sprocket for my 2010 rmz250 but all I'm seeing is silver and black for my bike, could I fit lets say a 50t blue sprocket made for a yzf250 on my bike or is it different bolt patterns?
cody g on Jun 19, 2017
BEST ANSWER: Get the Renthal TwinRing it comes in Blue. This sprocket maybe ultralight, but it doesn't last very long.
Will this sprocket fit my 2007 yz85? Just confused because my bike only has four bolt holes and this one has six?
seth c on Jan 22, 2018
BEST ANSWER: Yes, this will fit your machine. You will just need to make sure your machine is entered in the drop down boxes above the product image. This picture is generic and doesn't necessarily represent the actual product you will receive. If your machine is listed in the drop down menu, it will fit.
What size is perfect for my crf150f 2008?
Jérôme G on Aug 27, 2017
BEST ANSWER: I would be happy to help. Do you want to stay with your stock size sprocket?

A shopper on Apr 11, 2017
BEST ANSWER: What is the make, model, and year of your machine?
WHAT COMES STOCK ON 2017 YZ 125 ?
A shopper on Mar 21, 2017
BEST ANSWER: The stock rear sprocket is a 48 tooth for your machine.
