Steel or aluminium rear sproket

19 posts in this topic

What are you YZ-ers running for a rear sprocket? This Renthal aluminium one didn't even get me thru one year, that's about 100hrs for me. Since I ride primarily woods I'm thinking I can afford the extra few pounds for steel. Also would you change out the rear without doing the whole drive-train? My chain and countershaft are good for another few months but the rear is toast and I don't want to spend the bucks for what I don't need yet.

I spoke to a guy that does a lot of desert racing and hare scrambles and he swears by the stock yamaha rear sprockets. He says they last forever. Another sprocket that is supposed to be pretty good is that sidewinder trimetal sprocket (something like that). I don't have any experience with it but it is supposed to be pretty good.

Sunstar makes the stock one, I have tried the Moose rear and liked it, very light. I have a friend, that owns a small parts shop, and has a 450 KTM. He says it lasts a lot longer than the Renthals, light and looks pretty good too. It is black. It will be my next sprocket. Of course my stock rear is barely worn and it is over 2 years old. :banghead:

I second the JT steel sprocket :banghead: They are really long lasting sprockets and trust me.. You will NEVER notice the extra few ounces it will weigh. I'm on my second season with the JT sprockets and they still look great, and I use my bike primarily on the street so they have lots of miles on them.

If you want inexpensive durability and don't care about an extra couple of pounds, then go with a JT brand steel. Should be available for around $25 and they'll last as long as any steel sprocket out there. If you want the durability of steel and the weight of aluminum then you can get a fancy steel sprocket such as the Ironman. The Ironman are pricier, but come with a one year unlimited mileage free replacement wear warranty and weigh a lot less than the JT. Google for the price, it varies a bit. In the woods, the JT would probably be just fine.

I just found the old stock steel one for this wk/nd at DP, but I'll take your 51t off your hands the next time we see eachother Bob, thanks. :banghead: Then when it wears out and I go for the whole new drivetrain, I might go with the Ironman as recommended.

PS. What other used Yama-goodies you got up there for sale? :banghead:

I have the above-mentioned Sidewinder Tri-metal sprocket. I have about 49 hours on it, according to my hour meter, and there is literally no wear whatsoever. I highly reccomend them to anyone. Well worth the money. You will go through alot of chains before you make a mark in this sprocket.

the only other thing i've got you might need is a wr coolant recovery tank,most all the goodies are gone :banghead: i also reccomend the sidewinder tri-metal,after using both ironman and sidewinder i can honestly say its worth the extra $$ for the sidewinder. its fit and finish is far superior,and the ironman gave the bike a harsh,tinny kinda feel that had me worried about the shaft bearing and tranny;enough to take it off after 2-3 rides. the sidewinder has the aluminum center that seems to buffer any harshness from the tool steel teeth :busted:

Renthal - Steel... Going on 2 -Years and too many hours & races to count. Keep in mind that if you replace the front, rear and chain together, you will get the most life out of all...I am convinced that a good chain and good chain maintenance - including cleaning, will make both sprockets last much longer regardless if steel or aluminum.

Sometimes the front will wear 1st and I'll either replace it for 15-20$$'s with a new front sprocket or swap with a previously not too used front. I don't think I would ever replace just the rear sprocket with a new one - due to cost and wear.

On the issue of chains and sprockets.....

01 YZ426- stock gearing 14/49 right?

what length in chain links is stock and 14/50 combination? Anyone know and what chains have you guys had success with?

Stock chain lenght is 114 links.

going up one tooth size is not going to increase the lenght enough to add 2 links. Dont think of lenght in terms of teeth, think about it in overall sprocket diameter, as if they were pulleys.

BTW. I was running a Sprocket Specialist SX sprocket with RK X-ring chain. Sprocket Specialists now call that same sprocket the Titan Tough. It held up really well, but I clean the chain religiously and never ride in mud or sand. So that makes a big difference.

I spent $300 for Krause Racing (sidewinder) sprockets (laser cut stainless) and non-o-ring chain. Chain broke in about 20 hours, and they just wanted me to spend $250 to replace everything again. Sprockets show NO signs of wear, so am just putting new RK Gold chain on it. Know that's not kosher, but will give it a try. Was very careful with chain tension, lube, alignment, so very surprised it broke. So sprokets seem good, but I'm not impressed with their chain. I've seen a few 450's literally tear an aluminum sprocket off the hub, so watch those sprocket bolts!

I'm not allowed to post a link, but that isn't the best price around. Google!

And Brian389, the sprockets come off the hub when something is not setup correctly (or you pick up a rock). For example the chain is too tight, or the chain got packed with dirt and became too tight. Be careful, it's not uncommon for hubs to break in that situation.
