    I was going to call :205

    but this is a recall for some of the other LC4s...

    no new rim for these folks; some kind of clips to cross link the spokes (seem those somewhere before...). thanks for sharing; too bad your thread title doesn't stipulate.

    :huh
    what a cheapass fix :baldy
    you'd think the real fix would be new spokes...securing them "just in case" is asking for trouble as thats an admit that they know somethings wrong. stupid just stupid on KTM NA part.:deal

    oh lordy,,,,when i read about this,,,i realized someone at ktm is getting desperate.

    tying up the spokes where they cross either with safety wire,zip-ties or copper wire with a dab of solder are old competition tricks for keeping your spokes from flailing around should one break.

    i suppose the strategy is to minimize losses from having their broken spokes inflict even more damage.....and possibly slow down the requests for wheel replacement,,or????

    do not confuse a band-aid for the cure to your problems!!!!

    it's a step up from wiring the spokes together like some bicycle racers did for a stiffer wheel. a very short step.

    yup...and it still doesn't solve the problem of a flat tire from the broken spoke nipple.
    I still think KTM just opened a huge can a cluster fuck with this instead of spoke replacement...laws suites here we come.

    The problem with the spokes shows itself after hard braking use on pavement. Just keep roadracing the machine and you will ruin the wheel. If you are all packed up and doing pavement I would suggest you use restraint. Just be glad the machine has such a good brake up front. It will probably save your life. Maybe you would like something to increase the unsprung weight. Check your spokes grasshopper...or die.
    And buy a spoke wrench.

    superlace it and you can even roadrace it or supermotard it or mx it or get off just looking at how awesome your wheel looks:clap

    end of story...

    Ive got a newer model but still I wonder what I should look for

    Is it just a matter of loose spokes?
    Nipples pulling thru the rim.
    Cracked hub flanges?

    the broken spoke pictures I've seen have been random but mostly one or two inches down from the nipple. so, mid spoke. so I think it's a quality control problem with cheep steel.

    and as for
    :lol3 thats funny.
    I can see where you get the logic for it but jez, they are ment to take a hit off road as well as on road why would this couse Spoke failure unless the spokes were suspect anyway?
    latery stress as well as load could flex the wheel but they are designed to do this to some extent and survive. spokes breaking is not part of the equasion.

    surly, don't you have the black rims (Behr)? a few have found those too wide for any tire they found to protect. The result was dings or bent rims where they felt a narrower rim would have been protected by the tire. I think the thought is the stock black rim on the 04 and later bikes are more road-biased.

    The reason we got told for the other recall was because a design fault with the hub could cause the spokes to break on bikes with a 320mm disk. So I think we all assume its to do with the extra braking power from the bigger disk that caused breakages.

    I didn't have any break, but they had a fair bit of surface rust. cheap steel ? that be my guess too.

    since my long gone days working at Scuderia West in San francisco I notice how poorlly made the KTM wheel were, specially some of the spokes with 5/6/7 treads showing (KTM used the same lenght spokes, even if you need to have diferent sizes [sometimes even four] to have the minimum amount of treads expose) specially for me after building really high end bicycle wheels for ever, that is a absolute NoNo since every tread expose is a stress risser waiting to happend, ergo a failure in the long term, not to mension the spokes and nipples corrode like nothing...

    I just wonder why i took so long for this wheels to become a issue..

    Yeah, what Woody said :nod

    I swapped out my KTM wheels (front in in for the recall right now) for some Woody specials - could not be happier! :thumb

    I just got my spoke recall. KTM states it is for 2000 SXC 400, 2003 & 2004 SXC 625.
