sprockets alum vs steel

yz 426 f tight trail use mainly and am changing rear from 49 to 51 tooth what would be best and most durable

Steel but make sure the chain and the counter shaft sprocket is good if you put a new sprockets on with a bad chain you'r new sprockets will go bad fast same new chain on worn out sprockets it will make your new chain wear out much faster.

I normaly change them out in sets unless I know the other in great shape.

Steels Sprokets can cost alot less than aluminim sprockets and taken care of they can and will last much longer than aluminim sprockets.

I only will run is steel when the sales person at the bike shop trys to sell me a aluminuim I tell them I dont want that junk normaly it's a young kid that sold on the hip all the big time racers use them.

Yes they are nice sprokets but $89.00 for one of $20.00 for a standered steel sprocket that last just as long.

13/50 on my 426 and I find it great all around.they are steel,I used aluminum on the kx and only get a season out of them,last set lost all its teeth and I didn't notice it until I went to change the tire.Running an O-ring chain also but they are noisey,I get alot of chain slap unless I run it tight.

Steel all the way!

If you aren't racing mx, I say steel. If you're looking for every gram possible, aluminum. I've had great luck with my ProTaper sprockets which are aluminum. Also had good luck with SunStar steel sprockets. If you're looking for a great value and long lasting, definitely steel.

Well I have seen on motosport they had kits 160$ I think they were, with a front and chain.

DID 520 X ring chain $99.00 http://www.motorcycle-superstore.com/14/71/969/42856/ITEM/DID-520VX2-X-Ring-Chain.aspx?SiteID=SLI|Did%20Chain&WT.MC_ID=10010

The last chain I purchased was a Renthal chain O -Ring POS but I pick it for cheep but I will never again buy a renthal chain it keeps on streching the DID I have ran on many bikes over the year best chain I ever ran.

I like DID I also have had RK it was Okay I have now a Renthal like I said never again but when the sproket and cain go bad I get my self anouther DID X ring chain.

As for Sprockets I seen front sprockets On E-Bay for $7.00 for Front free shipping rears for $20.00 Free Shipping and NO tax, This way you can run any combo you want I running a 13 in front and a 50 in the rear.

If you were closer I give you a new DID Non O ring chain someone else gave me never been used I only will run O or X ring cjhains.

I don't need a chain, My bike is literally brand new.

I spent like $100 on a DID x-ring and the POS stretched every ride...never again. I prefer the "Primary Drive" chain and sprocket combos Rocky Mountain sells. I get a chain and sprocket combo that last six months of riding or racing(Hare Scrambles) 9/10 Sundays a year. Can't go wrong for $89-99!

I never had any Issues with a DID Chain with 8,500 lbs tensile strength I ran then on my 64 H/P KTM 560 and my 60+ H/P CR500 .

Which DID X ring were you running I have a Renthal O-Ring chain tensilestrength of 5,300 lbs it streches a lot just waiting for it to fail and on my 52 H/P Yz 426.

It's a stretched chain that wears sprockets, so if you want the cogs to last, invest first in a good high quality chain that doesn't wear right away and will hold its correct pitch dimensions over time. I run Regina's ORN6 sealed chains exclusively ever since the first one I tried on a CR500 some years back. The chains last me about a year and a half of riding in general and desert racing. I replace them when they are stretched 1.5 - 1.75% over spec's, and the hard anodized Tag Metals aluminum sprockets I run are still in serviceable condition at that time, sand and everything.

well steel it is and 13/50 sprockets .. ive ran the did chain on the 250 i sold and never had any problem with it ,thanks for all the input on this thread
