    I am considering a lc4 and read that the 05 has an extra oil jet at the base of the piston. I can geta 05 for a little over 8g and wanted to know is it worth it? I will be commuting on it some days, Are they fine running at 75-80mph. I think insurance and a more conservative riding will be better for me than a 950. Longevity of the thumper? Seems the trend in bikes is moreeeee power which for me is moreeee trouble. Sounds like the 640 has plenty of power and will run at freeway speeds fine . please give your inputs? Tom

    The bike will do it, it has the power. Maybe a 17 tooth front sproket off the Duke ( you'll need the Duke case guard also for clearance ). I can't comment on the oil jet, I haven't heard anything about changes in the '05. If it got an oil jet, I would have thought it happened in '03 when they did several other changes. Not in '05 with supposedly a replacement due next year.

    I hated mine ('03) on the highway. It was a real buzzer, my SXC doesn't have rubber handle bar mounts and it's actually smoother. Just luck of the draw I guess. The low fender on the '04 & '05 should help in the crosswinds.

    The only advice I can think of is this: The 640ADV really is a dirtbike, unlike say , a KLR. It will always feel like one. If you are happy with that, you'll do fine. If you are not going to do real off road riding with it at some point, you'd be better off with a 950.

    Are you in Europe or Canada? There were no 04 Adventures in the US and I haven't heard of any changes to the 05's other than we're supposed to get a few and they're going to be the 04 Euro spec with low front fender. Don't know about the oil jet change - I'm skeptical, but anything is possible with KTM.

    On the LC4 highway issue, as the previous poster said, it's like riding a big dirt bike on the highway. I was going 80 yesterday on the freeway, and it does it fine, but it's not the right tool for the job. If you anticipate much freeway and you don't need the somewhat better dirt capabilties of the LC4, I'd get the 950 which is a vastly superior pavement bike and probably a heck of a lot more reliable and long-lived in this application.

    You can just grind down the stock chain protector a bit and the 17T will fit right on with that simple modification with a file. Some 640/625s vibrate more at an idle and less at running speed and some are the reverse of this. If you get the former you are lucky.
    My 950 was wonderful on the road (after jetting, cannisterectomy, Remus Revolution mufflers) and was a really, really big dirt bike in the nasties, but it did everything my 640 would do. If you are running on the street all the time spring for the 950 with mods and if you are doing mostly dirt get a 450 or 525 and put the lighting kit on it from E-Line (www.elineaccessories.com). Forget the 640. My 450 is much, much smoother, great on the road, absolutely stellar in the dirt and a real surprise for car drivers when you wheelie across the intersection from a start. You can put the 3.4 gal KTM tank on it and get really good mileage. It is so much fun I cannot stay off of mine. The compromises: 1) limited oil capacity (change it every 500 miles), 2) limited charging capacity (if your battery is up it will keep it up and if not, not) and 3) you have to put on the lights and brake switch to make it passable (not big deal though) and 4) the seat is really narrow for road work but just the hot ticket for the dirt and last, 5) you should change out the camshaft bearings and seals at about 90 ~ 100 hours (mine at 40 hours looked brand new). As Hal Willis, the great Triumph motorcycle engineer once said, "You pays your money and you takes your choice."

    Thanks guys, Can the 525 handle freeway speeds and is there larger fuel tanks? Does anyone have knowledge of the husquavarna 610 with the 6 speed tranny? Are they ok on the freeway. I like the way the look, the reason I was looking at the adventure was the 28l fuel tank. Is there aftermarket fuel bladders that can be used on the bikes with the 3-4 gallon tanks? All input welcome, this is the place for me to get educated. thanks, Tom

    I can address the 525 but not the 610. (The '05 510 would be a better bike all the way around I would think.) You can put a 15T countershaft sprocket on the 525. You might have to file down the chain guide a bit but it will go. That would help with highway speeds. The 3.4 gallon KTM tank is about the largest and it does keep the weight of the fuel pretty low. You can get another gallon or so with the new rear number plate/gas tank that is just now available for the 450/525 (check the recent Dirt Bike & Dirt Rider magazines.) I would willingly ride my 450 up to 100 miles a day on the highway but I do not know if I would do more. I would also vary the throttle a lot and not hit it hard in the top two gears for more than just passing. If you really want to fly you would do well to consider putting the cush hub and rear wheel off the 640 on the 525. It fits right on -- you just flop it over since the chain on the 525 is on the opposite side from the 640. (Check the '05 frame/swingarm clearance since it is new. It looks to be the same as the older 525/450s, however.)

    I think you're right about the extra oil jet - try translating Sommer's site which gives an indication of what's new for 05.

    This gentlemen keeps asking about pavement and we keep talking about modifying super-hard-core dirt bikes to make them barely tolerable for short distances on pavement. He can correct me if I'm wrong, but it sounds like he mostly wants a dual-purpose to ride on the street.

    Mark, I ask about freeway because I dont want to pay good money and be let down if I want to ride it to work. I am not hardcore dirt but I had a 03 tiger and it was fast but I definetly would not be comfortable in the dirt on it. I like the looks of the KTM and the fact you are getting top components. If I could kill 2 birds with the 640 adventure I would prefer too. I know the 950 is nice but it is expensive and insurance would cost more. I guees what I am trying to find out is the 640 capable of both?

    yes.
    abit uncomfortable on long hauls of freeway but if it's just to work it's just as much fun as you can have knowing you're going to work. :nod
    Whats your local?
    long strech of commuting?
    Stop and go traffic? of flat out 80 mph all the way there?
    I find that cruising 70 for longer than a few (10-15 miles) is to much like work but if itsa short hop on the freeway and around town it can be a blast.
    I find I look for new ways to get to and from work just to ride it. :D
    It's much more the urban warrior than the freeway cruiser. :thumb

    If you can, just ride the 640, I find it hard to imagine that you would be undecided even after 15 minutes on one. I expect your either going to like it or hate it. The 640 can handle just about anything you can throw at it, the question is can you. I would ride mine cross country, but then I used to do 1000 mile days on my RZ350.

    IMHO, any thumper is going to have a shorter, on average engine life, then a multi in most cases, but they are still pretty robust.

    I sure would not pay $8k for a bike that is going to go offroad and will depreciate just like any other bike, lot's of 2000 to 2002 ADV's have had asking prices from the high $3k's to just under $6k. You should be able to get into a used bike with some options/assy's factored in for just about half that. Not to mention if your going to D/S it, the bike will be getting beat up, so might as well get one with a few scratches to start with. The 2003 has some nice improvements, but just about any year will work fine.

    Valid points. I would add that, having done up to 1,500 miles in 5 days mostly off road on my 640 LC4, if you are doing mostly off road the RFS 450/525 is an excellent choice as well. (Deep sand on a RFS is simply fun and on a 640 a real chore.) If you are commuting and expecting more miles the 640 is better. Used is cheaper -- but beware. I have seen good looking 640s that have had almost zero maintenance. They are expensive to repair if you need internal engine work. On the other hand, the 640 is likely one of the most durable engines ever built. I have seen very high mileage (six digit) 640s. Problems with 640s are almost non-existent. Vibration is the only complaint. That can break ground tabs on voltage regulators, etc. If I were riding around the world the 640, not the 950 and certainly not the RFS, would be my first choice. It is tough, simple and you can do all the maintenance anywhere.

    Thanks, Stu. I like the reputation of KTM. The 640 sounds like a good balance and I finally heard that if you maintain them you can get alot of miles out of them. The kawi does nothig for me looks wise and seems by the time you upgrade to the level of the lc4 you might as well get the KTM and the pride of owning one. Any body get over 40,000 out of them? Still looking for support not trolling.

    Oh, wait, you forgot the low 950 style front fender (and most likely cross over brake line) for mud! Just what we need here in the midwest with lots of sticky clay and muck.

    I am new to Adventure riding and recently bought an 01' 640 ADV with a little over 13k on the clock. In the 2 months since I got the bike I have done close to 2000 miles, both on and off road. I have a short commute in surface street traffic, I ride on the freeway for various other trips and have off roaded the thing on some pretty tight trails. I find the bike is a good compromise for all of these situations. The previous owner had installed a BMW wind screen which I removed recently for a trail ride. It definately makes a difference without it on the freeway. I also changed the gearing from the 17-42 as purchased to 16-45 for trail riding. Obviously the freeway speeds suffered but it is still doable for short hops. It just depends what you want out of a bike. I came from desert racing and have never owned a street bike. I am used to full on race bikes and I find that the 640 is a pretty good dirt bike unless you have to go through a bunch of whoops or deep sand due to it being very top heavy. On the street it vibrates but that is the nature of big thumpers. I have made one long trip on the bike (400 miles, when I bought it and rode from Phoenix to LA) and am going to be making a trip for the 640 tech day in Jan up to the bay area. I wouldn't do that on a 450 or 525.

    I would, but I would pick my route -- up the coast highway with excursions off onto the backroads of the coastal range. Great riding up there and some dirt.

    Mike , I am surprised you didnt get the 525 mcx desert model. It has a 5 gal tank. I think the 640 would be better for my freeway usage. Does it sound like the 05 has enough positive changes to justify buying over an 04?
