Having steel teeth and aluminum body helps to cut weight and increase lifespan. Also, it does a pretty good job at putting the power to the wheel.

This sprocket looks great and lasts longer than any other off-road sprocket out there. Would recommend to any rider.
Awesome purchase! Will be getting these on all 5 bikes!
I have been using the Renthal Twin Ring rear sprocket for a few years now, and they are bullet proof. I have a 450 and they hold up and get almost a full season of racing and riding on it. Quality is top notch, what you come to expect from Renthal. Highly recommend it, no need to try any other sprockets.
This is a fantastic sprocket that appears to have a life expectancy exactly equal to the life of the chain you choose. I always replace both sprockets and the chain, slider, guide all together. The weakest link in my sprockets/chain/slider/guide set is the chain. The chain stretches to the point of replacement before either the counter shaft sprocket or the driven Twin Ring is sharp/ready for replacement. The chain you buy (haven't tested with an 'O' or 'X' ring yet) will give up the ghost before the Twin Ring sprocket. These look great as well, but my interest is primarily performance and durability. NOBODY can tell a difference in power due to the minimal extra weight of this sprocket. If you're worried about extra weight - DON'T WORRY.
Looks great and will last a lot longer than aluminum.
Looks great..my only question will be durability since it's not steel.
Great product for a great price, delivered to my doorstep on time!
Little to say...light weight, excellent durability. The only sprocket we run once we've established best gearing.
Money well spent
Nice light and strong sprocket. No complaints here. This thing can take some punishment.
Very durable, not very heavy. We have about 15 hours on the sprocket and no problems, looks brand new.
I have a ton of hours on my Twin Ring and still no saw tooth! I am a bigger rider and used to run full steel sprockets for strength. Not anymore. This is a big bang for the buck sprocket.
I was looking for a product to stand up to the demands that motocross racing put on these bikes and Renthal was our answer.
I have about 5 rides on this sprocket and it still looks like the day I put it on. Happy so far.
Want to win and look good this is the product for you.
Gives your bike that factory look.
Used this sprocket on my 250f and now my 450f. Twin ring is the only way to go. now that they have them available with different colors, just makes them that much cooler.
First time trying this product and I love it..it's the best of both worlds and great prices
I have a 2009 CRF450R and this is the second Twin ring sprocket that I have bought for my bike! I have a ton of desert hours on my bike and this sprocket just take all of the abuse i can throw at it with minimal wear. Unless you have money you want to throw away on aluminum sprockets this thing is the way to go!!
Great sprocket. very durable would recommend to friends
