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.

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?


He Man

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).  ;)



He Man

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.
