    CJ / Oldhound,

    What all did you guys end up doing to the DRZ fork internals for this set up? I think I am going to look for a used set of forks, but I am curious as to what else will be needed to beef them up.

    Thanks :freaky

    You first have to determine how stiff you want the springs to be. Then you go to a suspension tuner to match the valving to the springs and the intended use of the bike. However, try them first and play with the clickers! Post 02 drz forks are fully adjustable.

    First of all, I would like to say that I am very much a n00b when it comes to suspensions. The following may or may not make sense...


    I figured I would just start with heavier springs and play with the clickers. Then, if necessary, go the route of new/updated valving. I have found different websites that will calculate a heavier spring based on the riders weight and intended riding style. However, given that the wee is a bit (:evil) heavier than the drz, I am unsure of how much extra stiffness will be needed just to overcome that. I suppose I could calculate the difference in weight of the bikes, and add that into the riders weight, but I don't really know if there is more to it than that or not.

    Did I mention I'm in a little over my head when it comes to the dark art that is suspensions...:lol3

    i wouldn't buy springs or valves until you've exhausted the many adjustment combinations, and also switched to synthetic fork oil, maybe in a different weight. it also depends on your personal preferences. for example, i don't care for a soft setup on the roads i frequently travel, while the next rider would say that soft is exactly what he's looking for.

    similar weight bike, i didn't change the internals on the DRZ forks at all. as far as i know, they're OEM stock.

    So are these going to customizable triple clamps? I am looking to change out the forks on my WRR with some WR450f forks so I would have those just sitting around. They are KYB 46mm inverted forks, what are you thoughts on something like that?

    It was neat to see your name in print again Craig.
    Motorcyclist Magazine, Jan 2014 issue.
    The article "Ready to Rally" about the KTM rally ride.
    11 days and 5,000 miles.
    What a trip!

    It is great that you are giving attention to the cheap seat guys riding 'Strom's.
    We are looking forward to more info about your kits & products to make our bikes more adventurous.

    It's funny.. I've been planning this whole winter on trying to get my DRZ400 front end on my vstrom.. and I stumble across this thread.

    I think it looks and performs great! And it's exactly the path I want to travel with my own vstrom..

    I'm hoping you come out with a kit soon! I'll be a customer if the price is right!

    thanks for the input guys.

    A custom seat is being made for this in the next few weeks that will flatten out the dished profile. Once that comes back we will be looking at other suspension height options as it will get lowered a little bit for the owner.

    The Skidplate and Center stand package will be completed once suspension work is done.

    We are still moving forward, now that the winter thaw has started to unfreeze our brain cells. :freaky

    I'm curious about more weight reduction on this, and getting a 31"+/- seat height, even at a travel loss?

    The current bike is getting a custom seat built to get rid of the dish, as this will raise the seat hight even more, a suspension mod will be done to lower the bike a bit for the rider.

    I'll get more pics up as soon as I can. Shop is booked solid for 1190 R&D that needs to be done by mid May, then the 650R work can start as I plan to test the new Skidplate/ centerstand combo on our Memorial Day test ride.

    Are you too busy or is the CJDL now DOA?

    Not DEAD yet!!! I've just been swamped prepping for winter. Summer went so fast. Even more so b/c I could only use one hand for 3 months due to surgery. Trying to get caught back up like a mad man. :freaky

    We have finished up the rear 17"x 3.5" rear spoked wheel built using KTM 950/990 hub and cush drive, a custom rear brake rotor and a custom set of bushings to fit the stock axle.

    - Why did we go with KTM hub and not other aftermarket DL billet hubs?

    Sprocket options. By running a KTM cush drive setup we can run much larger rear sprockets for better off road gearing.

    At the moment we are testing 14/50 and find it to be so much better in the trails. :clap

    The protoype Rekluse EXP is much happier as well. :evil

    We are now prepping for a Mexico trip this Jan. Next on the project list is to finish the skid plate/ center stand option. I hope to have to done in time for Mexico testing.

    Our route will take us down Baja, then over to Mainland. Copper Canyon, then back to USA.

    We've also been playing with front end ride height. We will continue to test until we get snowed in. I will try and post some current pics when I get the bike out next.

    So glad to hear you are still making progress.
    KTM hub sounds good and the Rekluse clutch sound fantastic!
    I will keep watchingÂ…

    And waitingÂ… :cry

    Thanks.

    The other huge plus, was we dropped 9lbs off the rear tire/wheel assembly over the mag 17". I was pretty surprised.

    Bike is going back on the scale tonight fully fueled. I'll report back with our true WET weight findings. :evil

    9 POUNDS?

    That is excellent! :clap

    Less rotating mass and less unsprung weight is win-win-WIN!

    I am sure the front spoke wheel is also several pounds lighter than the stock fragile cast wheel too. :D

    I believe this bike (along with CJ's 950) is in Mexico testing/riding as I type. Lucky them.:clap

    So Craig may not be able to reply for a while.

    Ah I see. I took a peek at CJ Designs facebook page and there's a few pictures of the Vstrom there.
