    Been reading about the Kush sprokets and ran across this thread. Thought you guys might be interested in this quote from the Kush web page:"The Kush sprocket dampening mechanism(everything bar the sprocket teeth) is covered by a full replacement lifetime guarantee."
    Seems like you may want to contact them for your free replacement!
    Let us know how that turns out.

    Any consensus on these as yet, are they selling the new 'V2' design as yet?

    I'm looking for something for a Husqvarna TE630, and it's pretty hard to find cush hubs for these it would seem, though i hear you can retrofit a KTM hub with new bearings and some new spacers...

    I'm fairly certain its the V2 Simple_One
    Just installed one on the 525. Feels like it's running a cush hub. If it lasts me 8000kms I'll be happy

    Okay, thanks, seems like a much easier solution than a cush hub, especially if you don't know for certain that you'll keep the bike forever. A back of the napkin type calc suggests there is stuff all difference in price based on the following assumptions (which I have just pulled out my arse and spent 2 minutes confirming on the internet - wild variance in the claims for longevity for all of the components mentioned below, these numbers are middle of the roadish, biased towards pessimism):

    Cush Hub - Cost $550, lasts 60,000km's
    Normal Sprocket - Cost $75, lasts 12,000km's
    Kush Sprocket - Cost $95, lasts 6,000km's.

    Costs:
    A Cush Hub + Normal Sprocket Combo = $0.015417 / km
    A Kush Sprocket = $0.015750 / km

    Result:
    Kush Sprocket Costs 102.16% of a cush hub + normal sprocket.
    (That is to say, it costs ~2-3% extra to use a Kush Sprocket with the above assumptions - assuming equal effectiveness in driveline shock absorption, thus negating the argument of counter sprocket wear and driveshaft wear).

    Those assumptions turn radically in favour of the Kush Sprocket if you sell your bike at say 30,000km's, simply because no one is going to pay you more for the fact that you already have a cush hub in a bike with 30,000km's on it even though it might last for another 30,000km's.

    I know I'll get abused by fans of both concepts (hub vs sprocket) for being a ragingly biased **** ************ for those figures, but as i said, the variance in reported longevity is ridiculous. Price assumptions are plausible.

    Just an update for anyone who is wondering.
    I refunded William's purchase as the sprocket was from a faulty batch( its polyurethane contained too much pigment which was acting as a plasticizer.)
    You can see from the photos that the teeth have a lot more life than 7000kms.
    We have a lifetime guarantee on all sprockets until their teeth are warn out.

    Thanks

    Yep, I'll give it a shot once I actually know what final drive I'm going to chase, but a 45 tooth rear is looking like a good option for the TE630.

    Edit: 45 it is.

    Umm, yeah
    my back of the envelope calculations worked out in favour of the Kush sprocket as well, particularly if you looking at 20 - 30000km per bike
    I might be a bit different from the norm here too but I hate spending money on bling & farkles if there are other alternatives, dont even particularly like working on or modifying bikes, just like riding them aye
    anyway, my Kush sprocket has about 1000km up on my WR450 with a mix of ' bootcamp ' riding, fast gravel roads, sustained high speeds on the bitumen & tootling around town, all good so far with no deformation of rubbers & it feels much smoother than not having one
    we are about to head off in a few weeks on a 3000km + desert adventure & I have no reservations about using this sprocket, will report how it goes

    umm, ok, after having just come back from a 5 day 3 State 3300km high speed blast out to Cameron Corner & back ( Gunnedah ) on a WR450 I think I am well qualified to report on my Kush
    it did about 1000km around here before leaving. Loved it. No sign of any issues.
    Day 1, at Bourke was fine. Somewhere between Bourke & Wanaaring all the " cush " dissapeared & it was driving metal on metal. So, somewhere about 700km on the first day was where it failed. It was still driving, I did think about just welding it up solid but didnt. We did about another 2600km of high speed ( 120 - 150 ) mostly dirt on that sprocket without any issues, it easily made it home. They are made out of bloody good steel, just wish the rubbers would stay in them aye

    what i will say is that at least if the rubbers fail, they wont leave you stranded in the middle of BFNW, which is a good thing

    Went to their website but couldn't find any way of contacting them from there. No Ph. or email contact info. They definately should have contact info on their website. Was thinking of buying one till this occurred.
