    I have a 640A with a set of superrmoto wheels as well (17 inch f/r). Can you advise if its a straight swap to a 990R (potential purchase). I recognise your suggestion of 19inch front but wanted to know if the hubs etc(Talon) will fit. I'm pretty positive about the front since its the twin disk model which I understand is identical to 990 but not sure about the rear. Can I just run it backwards (ie dissk on other side) ? Too much trouble, do I just ditch them and start new, is weight difference a worry ? Any help greatly appreciated

    The dual disc front hub will swap over, but the rear 640 hubs are too narrow and come with 20 mm bearing setup.

    We would have parts to build a wheel for the rear 990.

    The 950 and 990 hubs are the same, they used a wider disc side spacer on the 950 SE and all 990's.

    thanks zach

    i don't think so,,they are indexed differently...

    you can place the rear rim next to the front 950 wheel/rim and align the valve stem holes..the holes have to be pointed in the same direction..we know how to make the rim work,,

    HOWEVER..you really want a 2.50x19 rim on the front of the 950 sporting a 110/90x19 tire..ie the standard rim /compatible tire size used by 90% of all big ADV bikes:deal

    here's one Rx

    send rim in to have hole re-angled and countersunk to accept a different lace pattern...= $30

    you'll need i/2 of my superlace spoke set,,ss sbeefy spokes and ss nipples = $65
    plus S&H return to you one day turn around:deal

    you currently are running the oem X2 lace pattern,,we change half the pattern to an extra X essentially 1/2 of a superlace

    OR..you can buy the correctly sized and drilled rim ie 2.5xx19
    or...
    or,,

    Hi Woody,

    Thank you sharing your vast knowledge and expertise!

    Quick question: What is the best way to convert my 2008 690 SMC to an Enduro? I know there are clearance issues with the caliper. Aside from getting a complete Enduro set up, 21/19, discs, calipers, sprockets, what are my best options? I see lots of KTM factory wheels sets for sale from EXC models, will they be a direct fit? Thanks in advance, and I don't mean to :dhorse if this question has been asked already...

    The KTM 690 SMC front spacer's are different than the Enduro, but the hubs are the same specs. You have to use a x-laced rim to get the proper clearance for the caliper with the spokes, having it superlaced also gives a little more space for the caliper as well.

    The rear you can just use a 690 Enduro wheel, the 640 and smaller C.C. hubs are 20 mm axle and are narrower than the 690 hubs which are 25 mm axle.

    We have used hubs and a rear oem wheel if you are looking for extra parts for the dirt set.

    Contact us at woodyswheelworks@gmail.com with any specific questions.

    thanks zach

    So sorry,,sometimes a post or two 'falls through the cracks',,,,:wink:

    I believe we have done this before,,,I'll get Zach my right hand wheel wizard,,regarding the various swap-outs chime in on this...he's currently in California at the Rawhyde Adventure Rallye.,,,and I'f we haven't we'll figure how to :deal

    Thanks for re-posting. We cannot say with complete certainty what all it would take to make the 640 ADV wheel fit on the SuMo front end as we have not done this exact conversion.

    What's known(according to parts fiche) is that although the front bearings, seals, and hub are different the axle used is the same. So the front hub with the spacers should "fit" in the front end, but from there some food for thought.

    The main reason that an Adv wheel will not just fit on to the SM is because The 17" SuMo wheel is built with a x-lace(meaning from the hub to the rim, the spokes cross over the centerline of the rim) to afford more space for the larger brake caliper.

    The 21" ADV wheel does not have a x-lace so when used with the larger caliper, the spokes will hit the caliper. Sometimes you can just grind off some of the caliper for clearance, but believe you will need to x-lace this wheel to make it work. This would require a custom rim and custom spoke lengths to accomplish.

    To consider: if you were to have a x-laced front 21" or 19" rim laced to hub and mounted the 320mm rotor(only way to do it without making mods to the caliper). It should spin freely, but you will have a 320mm rotor on a 21" or 19" front wheel, which is a whole lotta brake for going off-road.

    The only way to go to a smaller front rotor would be to make mods to the forks/caliper mount, make your own conversion kit, or go with KTM 640 ADV front forks. There are many conversion kits to go to oversized rotors, but very few if any that go the other way around.

    We know of a few people who have the 950SM who put 19" and/or 21" front wheel on the SM and even after the time to make it happen, they regretted it because did not perform well off-road, was too heavy in the front end, etc. And one person was so fed up, he sold the bike, bought an Adventure and got SuMo wheels for it. Then the problem was solved.

    Now the 2001 640 SM is not as heavy up front as the 950SM, but similar concepts and likely you will find that it was not worth the trouble.

    Hope the above provides some clarity, feel free to let us know if you have other questions.

    Thanks,
    Chris

    well ya got Chriss's version of what can be done,,,,Zach is in the middle of the rawhyde rallye and has a lot on his plate,,i'll see if he may have time to chime in now,,but for sure when he returns next week,,,in the mean time ,,
    a few pics of your front end,,,

    chris's concern about your 320 rotor,,i think that there are caliper brackets available that adapt your caliper to either 300mm or 320mm..,so a picture is worth a thousand words to me,,,you may check with Bike Bandit or Cycle Hut or one of the other KTM performance shops.

    be patient,,,at least til i/we talk to Zach:deal

    Hi,

    Got a 2009 KTM690ER but have more or less all parts for SMC (wheels, forks, shock, brakes). Planning to also have 19/17 DS setup and use SMC 17x5"rear wheel.

    Front, I've got a SMC hub from a damaged wheel and found the below 19" rim on internet. It's a MX rear wheel and I think 2.5" wide. Will this fit? How about spokes?

    Does it soud like a good plan? Planned to use ER forks but can use SMC forks if a clash issue.

    The rear wheel will work great with the front 19'', normally we run a 4.25 x 17 so you can use the 150/70-17 and have much better tire choices for.

    We can modify the rim to work with the front hub, it looks like a 2.15 not a 2.5 which would be best with the 110/80-19 tires. It would be 235 to lace your hub/rim with new stainless steel spokes/nipples.

    thanks zach

    Thanks. OE for SMC is 160 so 150 should be OK? Also new KTM 1190 Adventure is 17" 170 rear so hopefully that size will be available from more manufacturers, believe conti trail attack from factory.

    Thanks for offer, bit inconveneint (cost) with shipping from europe back and forth and added tax (unless sent as warranty :) ) but might do it no one around here can do it.
