Does anyone have any experience with this?

Everyone seems to be selling quick chainge sprockets, i just want a normal steel sprocket on the rear for cheap, but  i cant find any, this isnt so bad and it looks pretty cool.


Or is quick change the way to go? the sprockets are cheaper for quick changes...

I dont mind buying a stock one, but i want to go up 2 teeth in the rear.

I have a quick change.  Makes life REALLY easy when swaping a worn sproket or just playing with gear ratios.

Even if you can go +2 in the rear...

...then the cush drives chew the eccentric at some point...


+1.

If you're the type to keep a bike long, or ride a ton of miles, or just burn through sprockets...you'll end up saving $$$ in the long run with a quick change set up.

If my math serves me correct, if you go through 2 sprockets, you would have already saved money with the quick change set up.

The steel sprockets last longer, but are pricey...you won't find one anywhere near as cheap as the quick change.

Most of the sprockets for the quick change are aluminum I think. You'd burn through those pretty fast.

Driven quick change sprockets = Aluminum
Afam quick change sprockets = Steel

STM=Aluminum

Who else makes them?

Ca-cycleworks has AFAM steel sprockets (quick change only) for $59, but the Quickchange carrier is $160. basically id go through 2 of these 1 piece ones, for each quick change. I put 18,000 on stock chains and sprockets.

is there no manufactuer that just makes a regular drop in steel sprocket so i dont have to go with a quick change setup? im probably going to put another 20k on the bike and sell it by the end of next year. so i dont care much for fancy shmancy  whatever. i may just go with a used carrier on ebay or something. 15/41 stock gearing isnt THAT bad. i just heard people LOVE 14/41 or 15/43 for commuting and figure id try it out.

It seems that due to the cush drives being in the sprocket, there are not too many mfgs making SSSA sprockets on the cheap.

The one in your original post is the cheapest I have found as of yet.

do all carries for the sss have the same BCD? 

I just got one (cant remember which) and im running an alum. JT sprocket but I think my next one will be a supersprox if I dont have to get another carrier...

Well i need a new chain. the last 1000 miles have really taken its toll. I thought i could squeeze some more life out of it, but 17,800 miles from stock chain and sprockets seems like im pushing it already.

Do you guys know of any 525 combo deals? I need a new chain as well.

There are steel sprox available for quickchange carriers; another good thing about a quickchange are the tabs that are supposed to prevent the cush drives from backing out and machining the eccentric/swingarm

your original link is a plain steel non-quickchange sprocket for $99
Supersprox makes a one-piece too, but they are a little more

I went with the Supersprox 42T rear and the EK SRX chain from monsterparts.  Wasn't that expensive and works just fine.  I like the 14/42 gearing. 

The 1 piece design Supersprox has steel teeth but aluminum carrier to reduce weight.

These last 5x longer than the aluminum sprockets. If you know what size sprocket you need, this is a good option.

SUPERSPROX "Stealth" 525 Sprocket: 748-998,848,S4R,MH,MTS,HM (http://www.motowheels.com/italian/myProducts.cfm?parentcategoryid=893%7CMonster%20Drivetrain&productID=5975&showDetail=1&categoryID=894|Monster%20Drivetrain%3A%20Single%20Side%20Swingarm&vendoridtodisplay=0&filterFor=&collection=168%7CEuropean%20Motorcycle%20Parts)

The all steel AFAM should last about the same--but make sure it is designed to prevent the cush drives from backing out into the swingarm. The better carriers/sprockets have a backing plate machined in to prevent this.

What about this guy... not at all cheap... but pretty :-)  Magnesium carrier, alum sprocket.

Side question: how hard is it to take the cush drives out and move them to a new carrier?

Cush drives slip into the carrier, and bolt to the splined hub.

just a report, i ended up getting the driven off monsterparts for $100 bucks.

The cheapest Quick Change is $150 and you have to pay $50 for the steel sprocket. thats $200.
For $200 i can buy 2 of these sprockets. so youd have to buy 3 sprockets before you break even.
3 sprockets = 18,000 x 3 = a lot of miles.

BUT if your cush drives blow up by then, then it negates itself....unless your just a cheap bastard like me and just weld a lip onto the sprocket and call it a day. Even then the fit for the cush drives is EXTREMELY tight, i had to polish the lip of the cush drive and stick it in the freezer to get them to even go in.

As for wear on my  rear sprocket,  despite 18,000 miles of use, it shows VERY VERY little signs of wear compare to a brand new one. I lined them up 1 next to another, theres such little wear on it i would of  been fine with  using my stock sprocket but i already bought a new one. Im using the stock front sprocket though because Driven sent me a 520 instead of a 525.

So im expecting this new driven sprocket to outlive my chain twice.

BTW, dont drop sprockets on your big toe. I gave myself a nice gash.

I think not having to remove the whole assembly and swapping the cush drives to replace the sprocket is worth the extra $$$.

and

when you drop a quick change sprocket on your toe, it will not do as much damage...  [cheeky]

thats like 10 minutes! and I'm so sure, when someone changes their chain, they go, hmm let me clean everything in there cause of buildup, and they'll take it apart anyway lol.

but ill agree with you on that last part, it would of defintelhy not hurt so much. :(

I stripped all the back of my cush drives allens. I was using the right tools. I blame it on soft metal. I got everything in by using vice grips to hold the cush drives. A real pain in the ass, getting them back out is going to be a nightmare.

i had no problem at all on mine. i used a vice grip the hold the inner and outer piece together then put it into a vice and then took the nut off. easy and then put it back on with some blue locktite.

Moto:

Supersprox 520 Gold 44 teeth?
Ducabike carrier, black?

 [moto]

whats stock on the 800? mine is 15/41 stock i am running 15/42.

Ducatbike carrier = bling blang.
520 = not enough life
525 = teh bombs.

800 is 520 chain and 15/41.
I get about 12k miles on a chain and stock rear sprocket on every other chain. 14/41 is my gearing at the moment.
Next chain will be on a 15/44 combo. Blinged out rear.
 

how many miles you throw on it?

 I had 18k on 525 chain and sprockets and though the chain was stretched, but not far beyond spec, the sprockets were looking barely worn. After tearing it apart, i would be fine with using my 525 chain for up to 20,000 if i actually took care of it.

Real world data?

Ducabike = Bling Blang = Fact
520= not enough life = relative to waht you consider good life
525= teh bombs = not a fact. 525 chains are not explosive.


<Serious hat>

A 525 is significantly bigger, youd need to compare the 2 side by side and you'll notice how much more mass the 525 has. The pin size is still the same, so the tensile strength is the same, but the load is spread over a much larger chain, so your sprockets last longer and so does your chain.

I got 18,000 mils on my chain and sprockets, the chain is kinked up from never washing it, but the rollers are all free and the stretch is not that far from spec, especially for a 18,000 chain that almost never gets washed.

I should snap a pic of how my sprocket looks compared to new. It doesnt have that much wear for 18,000. I would be fine using it for another 5,000, and id check again.

In fact i am using the OEM front sprocket, becasue driven sent me a dinky 520front sprocket by accident. I have no issues going to 2 track days in a week with it.

Yeah, but if all that is true, does that still prove true on relatively low power (2v duc) bikes?

Chain life? or more "parasitic*" drag? 

I though you were all about MPGs (e.g. shutting the bike off at stoplights).  ;)
 

i was shutting my bike at red lights...but then my bike went from 25mpg to 40mpg from breaking the motor in and i started lane splitting and rat running and speeding  ;) so i no longer do that. If i did, id be looking at 55mpg city!

Low power? HP maybe, but my 1000DS makes as much torque as a 998 Desmoquattro engine. and if your snappy with your throttle, then your chain has a habbit of going from slack to super tight often, which increase chain and sprocket wear, so a big chain to distribute that force will be better than a thin chain.
