    The 640 motor and the 625 motor are the same motor, both 625cc's. My '04 SXC has the "High Flow Head" and a Keihin FCR pumper, the older 640 LC4-E's did not. This accounts for a fair bit of HP advantage, but with a big tank and comfy seat, the bikes are basically the same. One other difference is the oil capacity, my SXC holds no oil in the frame like the LC4-E and Adventures, so this means 1.3L of oil as compared to ~2L of oil on the E and Adventure bikes.

    Major differences:

    SXC:
    lightest weight
    FCR Carb (more throttle response) (2004+)
    Aluminum Muffler (lighter, but requires repacking)
    Better Suspension (More Ground clearnace and travel)

    LC4-E
    Cush Hub (better on the driveline)
    Road legal from factory (lights, etc)
    More oil Capacity (Mine is usually ~2.5L.. I think)

    Adv
    as Lc4-E Plus...
    Big @$$ fuel tank... and fairing.
    Heaviest of all 3
    48mm forks.

    The cush Hub and the larger oil capaicty make for a better road bike. But I converted my LC4-E suspension into that of the SXC... the Beast evolves. Now, I just need to get a sexy lookin 18L tank like snaggler has.

    Leafing through some KTM brochures it appears the '06 and '07 SXC's have the same oil capacity, 2.1 litre as the other LC4s atleast here in yurope

    If your not using big pieces of it, dirt bike shops carry it or can get it as universal number plate backings... usually 18X24.
    Thick stuff with good adhesive.

    Thanks... I actually knew the major differences but you mentioned a few points that I'd like to know more about...

    1. Cush Hub - I have a spare set of wheels for an LC4. Is it possible to fit those wheels on a SXC ?? "Cush Hub is better on the driveline" - can you (or anybody) explain? I've never ridden a 625 SXC and can only imagine what that means in practice.

    2. Oil Capacity - That probably means more frequent oil changes. What is recommended by the factory? In an LC4 it's 5.000km. What is the reason for removing the oil from the frame in a 625?

    And yes - I also read somewhere that the oil capacity of an SXC is 2.1l or so... I think KTM has it on their Austrian website www.ktm.at in the SXC specs.

    I'll be grateful for the answers to my questions. I've had 2 LC4s and want to get something in the spring. It'll be either an SXC (mainly for the carb) or a 640. In both cases I'm getting an 18l tank + seat. I already have spare 640 wheels and brake discs. I'd probably ty to fit the 640 front brake on a 625 as well for on-road use :) Basically it looks like I'm going to turn the 625 into a 640 but what I'll buy also depends on what's going to be available. My budget is limited :) hence the 625 questions...

    Cheers,
    Losiu

    One other variation is the 625 SMC or supermoto bike. It has the LC4 with the oil in the frame and has some big ole forks, bigger than the EXCs and others from what I have been told with different triple clamps as well. I bought the 18L tank and seat for the dual sport riding but take the portly tank off and change seats for dirt only trips. I swapped out the motard rims for a 19" front and 17 x 3.5 rear with some Conti TKC 80s.

    The cush drive hub has some hard rubber inserts in it and the sprocket is attached to one part of it. The rubber simply absorbs shock and protects your driveline from the full traction tarmac affords.

    Nice bike KTMSER, although it looks like you are jetted a tad lean with those BLUE headers.

    Yes, KTM quit selling the SXC here in the states in '04, but continue to sell the bike everywhere else. After '04, KTM added the oil in the frame feature like the Adventure and greatly increased the oil capacity. So, it's just the '03/'04 SXC that DOESN'T have oil in the frame. This is how I understand it anyway...

    Here's my '04 SXC:

    [​IMG]

    I've done a few day rides and want to do minimal gear multi-day rides.
    Typical 80%dirt/20%pavement split.

    I would like to hear from SXC('03 & '04 with 1.5l oil capacity) owners who have put on 5K plus on the clock.

    What % pavement/dirt?
    How often do you change the oil?
    Have you/would you consider an aftermarket oil cooler?
    Is a cush hub required for the pavement miles?

    What I am trying to get a feel for is the ability of the SXC LC4 motor to handle a lot of dual-sport miles.

    The cush hub has rubbers to dampen the torque (power) pusles from the engine, not necessary when on loose surfaces (sand, dirt, etc), but when you have traction (rock, cement, asphalt, etc) it basically hammers on your entire driveline, transmission, chain, sprockets, rear hub, etc. The rubber smooths out these pulsations to be less harsh.

    The LC4 rear dampened wheel should fit on the SXC no problem, and it works on the 4T exc's as well. A guy I know just got an 07 525 and put a spare LC4 hub/excel rim combo on it.

    SXC without oil in the frame... probably just to save a bit of weight, myself I prefer the oil.

    Thanks for your answers guys, the bikes look totally cool :)

    Sounds like fitting 640 wheels shouldn't be a problem. I'd use them for street riding because that's what I do most of the time (unfortunately).

    I am also curious how often should oil be replaced in a lower-oil-capacity SXC?? I hope It won't become a PITA on longer trips...

    Does anybody know whether the bikes sold in Europe were the same an for the US market? I mean MIKUNI BST in 2003 instead of FCR 41, as well as lower oil capacity until the '05 model...??? Maybe there were differences for the european market...??? Just curious...

    Losiu

    P.S. A very important thing to me - does an SXC have a lock in the ignition (like a 640) ???

    heya loisu,

    Security eh? Here is one review of many methods:
    http://www.webbikeworld.com/motorcycle-alarms/
    I hear great things about Xena locks:
    http://www.xenasecurity.com/home/current/lock/
    Not sure if the alarm option would help you, but their locks are supposed to be very strong.

    I can't recall what the spec is on the SXC for oil changes. The idea would be that perhaps the SXC runs hotter, so the oil would degrade faster. I wouldn't necessarily think the road would make it run hotter than, say, slow single track technical riding - but who knows? Hopefully the SXC folks do; if not you can ride for a bit and send a sample to an oil tester (check with the long haul trucking companies for a shop) and find our for yourself.

    I am not sure about US/Euro model differences - might be best to ask KTM Austria.

    Hey Meat,

    Thanks for the links. I'm prolly going to get the Xena disclock with alarm, not really for security but for the noise it's going to make before they get it off.

    I can do a lot to protect my bike while in the garage (I learnt my lesson) but I go to work on it all the time and leave it basically on the street so the lock in the ignition will at least prevent the kids from getting on the bike and trying to push it away.

    It actually happened to my brothers Honda VF 750C. The seat was low enough for some kid to get on the bike and lift it up from the side stand. The idiot pushed it backwards a few meters and dropped it in the middle of the sidewalk. It's a heavy bike so he was lucky to get out of it with no injuries. The bars were locked but I can't imagine what would have happened if they weren't.

    I learnt to leave my bike locked and in gear even if I go into a store for a minute. The ignition lock won't help if someone is serious and wants to load the bike on a truck. KTMs need to be tied to walls or floors if you want them to stay where you left them. They're just too light.

    So... does the SXC have the ignition lock??

    It is set up to have a lock on the side of the head tube that uses the same key as the ignition, but it is not installed on all bikes.
    When I bought mine, the shop asked if I wanted it or not; it was no extra charge.

    You can get the owner's manual from their website:
    www.ktm.co.at
    It should say in that PDF.
