has anybody tryed this

The steel Primary drive sprockets on rockymountianatv.com and the primary drive o-ring chains are they any good or do they wear out fast? What about the sprocket kits are they worth the money?

I've never tried the PD chains but I have used several of their sprockets. Work great and wear good for the money.

i personally haven't used them but i'm planning on buying a set real soon. my brother orders almost exclusively from rocky mountain and has never complained about their anything wearing out to fast

what size rear are you looking for? i have a brand new titax ultra light 48 im about to ebay - pic

I've had one on my YZ250f for over a year and it still looks very good - i wanted one for my 450 but i cant find a 50 tooth anywhere so i bought an ironman :applause:

Yeah try this I just put on my 14 tooth front and 52 tooth rear sprockets and swaped from a fmf to a white brothers exhaust all at once on top of my allready somewhat heavily modified 2000 Yz 426f, and i washed it got it all nice and pretty did the heat gun trick on the stess marked spots on my radiator flaps or what ever they are called (which actually worked), and I spent so much time doing it and admiring the look of it now I dont have time to go for a short ride. Because of damn probation. Dont worry im not a axe murderer I'm on probation because I ran out of gas runnig from the cops on my bike, when I first got it I was having a blast riping ass around all the side streets in the neighborhood. Stupid of me to run I guess esspecially when low on gas I left the house allready on the reserve. LOL. Sorry Im so grumpy. Thumbes down. Tommorow when I ride her I'll let you know how the setup worked because I know its kinda tall gearing for a person who only runs MX by the way Jonneyrocket56 I have allways ran and still do run a renthal O-ring chain and renthal sprockets. I have a bike that makes tons of power and I ride very hard and very often, and I have found them to be great they last very long they arent very expensive The trick is when I replace or change a spocket or a chain I do all three at once, and I highly suggest O-ring chains just becarful when cleaning them and lubricating them. I clean my chain by putting it in a bucket of water and dish detergent and genlty scrub it with a tooth brush and lub it with Bell ray O-ring chain lube you should get at least 2 seasons out of it if you do this every race. And I personally suggest removing the front sprocket chain gaurd. Thumbs deffinatly up. I may be on probation and have horrible spelling but I know bikes pretty well. lol

They work really well. Personally I woudl not choose the steel rear. It is really heavy. You might not notice the difference, but expect it to weigh over a pound more than aluminum.

I got a steel one about a year and a half ago. I can barely even notice any wear. I suggest getting one and dont feel the extra weight is any burden, but then again i don't race.

damn airman, thats taking chain maintainance to a whole new level, I just put mine up on the stand kick it into first gear and use wd40 and a wire brush to clean mine. then I use the belray lube.

I just got this setup. It's still sitting in the box under my desk at work so I don't have any opinion yet. I searched here on TT for opinions on PD before I bought and saw almost all positive feedback on the sprockets and mostly positive on the chains. I figured it's cheap enough, what the heck I'll give it a shot. If it sucks I'll go with something else next time. But if it works then I saved a bunch $$.

Hold the ironman in one hand and the titax in the other, you will be glad you got the ironman. The titax last, but it's pretty heavy.

I did, acutally, and couldnt tell a difference really - i dont have a mail scale or i would weigh them to see, but i think the ironman may be a little bit lighter b/c there's less metal :applause:
