What is better aluminum or steel? I would think the 426 would eat an aluminum sprocket in no time.
I run a steel sprocket ($25) and have not had any problems with it, sure its a little heavier, but so is my wallet. Its been on my bike for about a year thru sand and dirt.
How noticeable is a heavier sprocket?
buy a steel one, you wont notice the weigth and will last 5x as long. Get a cheap one too (like Sunstar or Primary drive) dont fall for the expensive "laser cut" steel.
They say that unsprung weight is the best kind of weight to lose if possible, but don't think that you will notice a difference, other than not having to buy $50 aluminum sprockets every three months.
Upon the advice of this board I purchased a primary drive steel rear sprocket for only $14 and have put about 8 hours on it. The sprocket still looks brand new! Sure it's a little heavier, but once it was on I couldn't tell the difference. Along with the steel sprocket I bought a DID X-ring and have only had to adjust it once. For now on its steel sprockets and X-ring chains. There's no other way to go!
I heard Tim Ferry is running plastic sprockets to save weight and gain power. Or something like that.
in the gearbox ole chap....in the gearbox
I fell for one of those purdy looking $50 renthal aluminum sprockets and noticed the wear after my forst ride. They don't last and unless your trying to shave every ounce of weight from your sled, they aren't worth it.
On a side note, my friends Dad used to be a test rider for kawasaki. On his ZX1000 streetbike, there is, lo and behold, a plastic sprocket in the rear. I asked him if that was a race only part from a race bike and he admitted it wasn't a normal practice to run that type of sprocket on a street bike but he found it "lying around" and used it. The thing had several thousand miles on it according to my friend.
i think ill get plastic sprocket also and maybe plastic piston with titanium rings...
and I hear Dr.D is making a plastic chain to go with those cool plastic sprockets
I had a renthal sprocket, it was worn out before the new tire installed at the same time. I replaced it with a sprocket specialist unit. Very nice piece. I have 4 pretty good rides on it, with no visible signs of wear. Im steering clear of anything with the name of Renthal on it.
I am with gal
I just guted my whole engine so its just an empty case,
I velcrowed on the handle bars, took out the spokes (All But Four) each wheel. No fenders not seat, no gas tank. emptied the oil out of the forks and packed them ful of stirofoam.
The hardest part on riding it is pushing it all the way up the hill.
But Man is it lite.
I love these types of threads it really dipicts the Star-wars in our wants and rants....
The pay 400 bucks for the crabon fiber air box, that will make up the diff of weight
Oh Ya holding off at McDonalds Helps to

A company called Titax makes a stainless back sprocket for $60. I think I will give it a try and see how it holds up.
I saw on some web site, a company that makes a sprocket with an aluminum center section and is mated to a stainless steel ring gear. So the stainless part is only as thick as the teeth have to be. Kinda the best of both worlds really. At 110 bucks I have a feeling its not any more economical than a couple decent aluminum sprockets though. BUT THAT DISCOUNTS THE TRICK FACTOR, CUZ THAT THING WAS BITCHEN!
I PUT A RENTHAL REAR SPROCKET ON MY 400 AND GOT LIKE 3 WEEKENDS OUT OF IT THEN I WENT BACK TO A STEEL SUNSTAR
I HAVE NOW SWITCHED TO A AFAM AND ITS BEEN A MONTH NOW AND PRETTY GOOD WEAR
I THINK THE BIG H.P. JUST DESTROYED THE RENTHAL
I have about 12 hrs of mx on a ironman sprocket. It is steel and you won't believe how little material is in this thing. It weights 4 oz more than a renthal. It shows no wear at all and I also bought a very good standard chain (high $$ rk) and I have to adjust the chain every 1 hr of riding but no wear on the sprockets (front was steel renthal). So far it has been worth the money.
