    I couldn't agree with you more. Its strange, the DR being the first bike I ever climbed on and just felt at home. The balance, feel and handling of the bike is just amazing. I could do little balancing tricks on the test ride i would never have been able to do on my other bikes.

    Good advice, to be quite honest I like my Bikes as low to the ground as possible within their design parameters At 5,10, 1/2, I want to be able to touch the ground easy and a bike will always turn better lower to the Ground as long as it has sufficient ground clearance on the Road or the Dirt but if you taller than me and heavier than me you could easily cope with more travel, as long as ladder says it balanced front to rear ,
    I set all my bikes up with fork as far up as possible ( considering Ladders en-dos ) and then balance the rear to that,

    So say you KLX front end Lifts the steering head height by 25mm then you will need to crank the back preload up to raise the back a similar amount ( presuming your original balance was ok ) I think that's about 5 full turns on adjuster ring, if you cant get that much a 5 or 10 mm difference should still be ok youl just have to be more agresive on throttle in corner to unload front to allow bike to turn easy
    Also note that if your rear shock is old or worn your bike may tend to pogo stick at rear with to much preload and you ride quality at low speed may disappear ( one way to find out though try it first )


    There you go have to go work on circuit bike now to get ready for track day

    Cant wait for American pic;s :dg

    PS, Ed its the blue one on my signiture

    Wow, this is great bunch of info guys.
    BTW - just thought - Ray, I hope it will not scare you off on changing forks ;)
    In the mean time - since Robmoto working on similar conversion using Extremes, to answer some of questions....
    This is not first conversion I've done with front end swaps on different bikes, but first on my own bike and first time with WP stuff. I am not big fan of WP frankly. As ex-engineer I can see that they ran tolerances higher than Japanese stock items. But back to geometry. Here is information on WP Extremes if anybody needs it.
    -Motard vs. Offroader - 800rider, sorry about confusion there - no, nothing changes in suspension whatsoever. "Motard" setup is not longer forks on my DR, it's just wheels change, nothing else. Not really motards, just road bike is my aim.
    -Reason I mentioned rear preload adustment is to compensate change in geometry when you install front 17" wheel. With me on board DR (not only DR, every 650+ dualsport I tried) those bikes have tendency to kinda weave at 95+ mph if rear is too high. E.g. switching to motard wheels I will need to decrease preload on rear, because as we all know it changes ride height. But it does not need to be dramatic change. I have played with rear preload on many many bikes and DR stock shock suprisingly good for simple item. Plust I have black (hardest) rear spring and it works for my weight and luggage.
    - No, DR with WP Extremes sits precisely at same height (if not even 5 mm lower) as with stock forks.
    - Yes, there is danger of contact at bottoming when running 21" wheel. Extremes on Berg are only 20 mm longer than stock DR SR43, but they have 40 mm longer stroke (280 mm). However, in stock state on Berg they use long preload spacer which reduces stroke from 300 (KTM version of WP Extremes) to 280 (Husaberg). Increasing spacer lenght automatically kills part of stroke.
    Because "head" of DR requires longer steering stem for WP clamps than stock Husaberg and because Berg/KTM clamps are 3-bolt lower 2-bolt upper thick clamps now forks have only 270-275 "free" part of inner tube under lower yoke between top of dust seals and bottom of lower yoke. It means that forks will not be able bottom out at 280 mm but dust seals will stop against lower yoke (bad) if I will manage to compress all 275 mm of forks.
    However, fork springs I sources from Hessler are way thicker (5.25 mm vs. 4.9 mm), 30 mm longer but more coils and with all spacers I believe I intentionally "lost" some other 20 mm of fork stroke. E,g. we dealing with 10-15 mm more travel than stock DR. With 17" wheel it does not matter at all - it will not contact anything on bike as it is smaller diameter.
    -With stock 21 inch wheel on offroad MT21s I run - I just testing it with bike on the lift by pushing whole front wheel and forks through yokes to imitate bottoming out to see waht is works case scenario. Yes, there is possibility of intereference at full compression (I mean - full full, all 270 mm) but I am not done checking what intereference. I will let you know guys.
    - Since front fender will be mounted on lower part of fork leg it moves with wheel and worst case fender will hit bike, not wheel. I still got to play with this one to see possibilities.

    I am now tempted to drop from office, get back home and get my hands on bike, but must resist :wink:

    oops...fortgot - about intereference...
    On my test results - or worst case scenario - may be it is not when forks really bottom out, may be they bottom out earlier, I just pushed forks through clamps till dust seals contact lower yoke. I got 15 mm left between dust seals and lower yoke when wheel comes in contact with edge of "nose" (curable) but it also gets in contact...guess with what....my own self made front mount of crashbars :lol3 E.g. I need to split front mount in two, remove middle part of pipe and make new part instead. Easy job.
    So - all in all MUCH better than I thought.
    There is also easy possibility to reduce stroke "rigidly" by placing 15 mm spacer under lower bottoming out cone within fork leg. But I still try to figure out if it will affect somehow fork operation or not. I think it will not, but....need to think.
    Since my wheels for this summer will be 17" I will not have to deal with problem until first full-scale offroad ride, which seems to be distant possibility as I have too many travel plans for summer.

    Makes sense no wonder my DR so stable it backside drags slightly, ( eg opposite to Motard Bum up stance ) an XT rider suggested it pushed the front wheel when he rode it, but It doesn't for me though I may lift the Rear 10mm and try it ( I rode his XT660 but couldn't figure it out, the centre of gravity was higher and the front tucked I thought :D ) and not once did I lose the front Wheel on the Track with those settings even with the Cont Dual sport Escape on the front.

    Just out of interest my fork tubes are up 25mm in yokes and rear sag with me on is 100mm ( stock fork )

    Some more pic,s to keep things colourful till Ladder arives

    I was 17 and the year was 1980 that XR was new and cost $1995, as per my aviator ,then I was 500 rider and there was no such thing as the internet ( man Im Old )\
    Note 23" front, now thats a proper wheel
    [​IMG]
    The XR was ever bit what the the DR is today, It could cruise at 110kph on the Back wheel
    But in truth was not the tourer the DR is, A couple of Trips I did at 140kph and I was so tired from hanging on, Dont think Id even notice on DR apart from the tickets
    [​IMG]
    My first Real Bike a 1974 DT250 I was 15 or 16 and I still remember it cost $650 I though I was in heaven, but I wasn,t
    Side picture was a 1981 KLX 250 $2850 great offroad bad on road in that way Dirt bikes havnt changed
    [​IMG]

    Opps I may have started something, come on boys show us your old bikes ( just photograph the photographs in you old fashion albums)

    wow, that's cool pictures...where I born we could only dream of Izh Planeta Sport as offroader, no single possibility to buy foreigh bike (except Jawa and CZ) existed bck then in USSR.
    And even that only when you become a student or start working - price was sky high...
    So, back in 90 new "era" started in ex-USSR. I blame movies, but it was "choppers and bandanas" era. Yes, it touched me too, I must admit. I bough half-made Dnerp-boxer chopper, rebuilt it, finished and rode it.
    Funnily enough couple of years later when I managed to buy Honda VT250 I tried to ride ex-my "chopper" again as it was sold to my friend. Guess what? I almost s..t myself when I realized I have almost no brakes, it handles like barge and I can't trust it a second. That was end of "choppers era" for me. Since that time I tried many "proper" metric/HD cruisers and still hate them.
    I bet you won't find anything like that in NZ, Oz or US :lol3

    You make me feel like I was a capitalists pigs :D , Nice to see you getting in touch with your emotions with that reminiscing

    UMM ERR nice bike , still its better than my first , a FS 50cc Yamaha, even then I thought it was slow ( I was 13 years old 1975 ) and its prettier than the Yamy,
    BMW must have stole the design, A:wink:

    that's my second bike :)
    My first bike only rode once. It was 1937 NSU 600OSL, beatifully engineered "1937 sportbike" left behind by German army in WWII. It was just about moving and somebody messed up and rebuilt half of it. I almost finished main restoration (made replica of original rear part, serviced engine, built telescopic forks instead of missing girder forks etc. etc. etc.).
    I was not able to find working generator and electician I gave it too lost it!!! That stalled project. At that time I was so desperate to own rideable bike instead of begging friends that I bought this chopper garbage :lol3

    My second bike was that (VT250 grey import) - paint job? :evil Took me ages + 6 layers of clear coat). At that time I had in my garage 4 bikes of my friends too and had possibility to sometimes ride them as I was working on them - an NSR250R, CX500, GSX400 and XJ750.

    Sorry. It's boring today at work. Everybody on vacation, too much time on my hands :lol3

    I was just thinking of starting the USSR conversation yesterday.
    The thing is that I'm convinced that people who originate from Soviet union or from areas that are influenced from the Soviets are DIFFERENT.
    I was about 4 when the Soviet Union collapsed and the Internet already existed but STILL... I can remember that the thinking and the possibilities for young motorcyclists in Estonia were the the same as bluesman described even 10 years ago - that makes 1999 - after EIGHT years of independence.

    We (and I mean people that were adults by that time too) couldn't really use internet. And we still didn't have the money to buy Japanese bikes. SO these Dneprs, Urals and "Dnerprals" were often built to be choppers... HELL! Some guys are still building them. Luckily the trend is changing to restaurateing. Seven years ago I was thinking of building a chopper - now I would restaurate.:clap

    But the thing I wanted to point out yesterday was the "Russian mechanics syndrome". I'm sure I have it and I blieve Bluesman has it and definately many of my friends has it.
    Up until the end of last century (not to talk about the times of the soviet union) we didn't have either access or money to properly engineered machines. But we had A LOT of "homecountry's" stuff. It was normal that in the weekends men were in the garage cleaning the carburettors and changeing parts for he's means of transportation, because it was "evil" and "capitalistic" of you to change cars every ten years. When you got a permit to buy a LADA you were THE MAN! Unfortunately there were times when you needed to join the socialists party (is it really spelled so? :rofl) to get the permit.

    So my point was that many of us in this thread are mechanics like that but for this side of the world that is untuched by the soviets I believe it's more of a exeption. People from soviets are born raised like that. The nicest difference is that nowadays you aren't a capitalistic pig if you have three western bikes in the garage.

    Maybe my thoughts are obvious, but somehow wanted to express myself :evil

    you got it spot on. This is indeed all true.
    In my case situation worsened by the fact that my father is brilliant engineer and I was raised like that - "man should be able to build airplane from garbadge" :) and I studied in graduated after 6 years to Technological engineer - mechanical engineer and I was real good at it. As I started to work in the area USSR collapsed. I had to bail out to have income and went into IT business. But I still have that "itch" to use my knowledge and I like it. So, when I getting more tools and machines available to me it just get's worse and worse. I can't stop fiddling bikes or any really mechanical work I can get my hands on. I know quite a few people like me ex-USSR.
    Generally I do not think it is good. I envy people who can just buy bike and ride it way it is for years. It's good to be handy with bikes, but endless modifying takes lot of time I can spend riding. My excuse is that I don't fancy just weekend rideouts anymore for some reason, I need objective, scenery and distance to enjoy riding and prefer to stay away for crowded areas...which is impossible in Belgium.

    Bluesman where exactly in USSR did you live? You have mentioned the fact quite a few times, but you have never said the name of your homecountry.

    This is why I may keep the forks etc and save up for a Hagon or Wilburs shock, then get the whole suspension set-up sorted. Probably by someone who can twirl spanners while I drink tea and take photos :lol3

    Oh, forgot to ask; assuming I get the forks done, is the easiest way to upgrade the braking still to buy the nordwest caliper from ebay?

    Always wanted to see USSR, more specific, take a train ride on the Trans Siberian Express. Someday...

    I'm just a lowly mainframe programmer. I always look in awe when people take things apart AND assemble it again. Never fails to impress me.:D

    Correct, but to be specific - it will be best inexpensive upgrade. Rememeber - you still will have to get adaptor made.

    Drinking...well, I am not that trained anymore. Too much time in Belgium.
    But I still can drink more without problems than any of local people I know. I guess we born like that :wink:

    But Russians that can drink more vodka than Irish - that means they never quit training :lol3 I have some friends back in Kiev who are totally normal people who does not drink often but can take uncountable amount of vodka and then go to work next day :lol3
    Difference between proper vodka (forget about all this Smirnoff and Absolute stuff, that's no vodka) and good whisky is that vodka does not act on you almost right away, it takes time. Many people do not know it and getting "too far". As long as you need to stop before you feel hopelessly drunk and as long as you don't mix it with anything, taking small cold shots with plenty of food and pauses between -you will be OK.
