    Well, that setup seems to be an abandoned project, actually.
    It actually is (read: was) an Oryx rear frame, Oryx seat and the middle tank used in both, the Oryx and Rally conversions. What doesnt fit in the whole image is the Rally rear tank.

    It's rather hard to communicate with the seller, though, as my italian is not that good :p

    And I am not that sure if I even need it, I mean, why would I need a 3rd rear frame (already have a steel and alloy one), a 3rd middle tank and a 3rd seat, only thing I dont yet have is the Rallye rear tank :lol3



    (Anyone interested in the Trofeo Kit minus the exhaust?
    Yep, I am serious about that :deal)

    Hey, I got some Parts from the Touratech Rallye Kit today, including 2 lock adapters.

    They are machined from a single piece of aluminium and usually meant to be installed on the WP fork upgrade from Touratech, but it shouldnt be too hard to adapt them to the YZ forks.

    One is already spoken for, but the 2nd one is still up for grabs.
    Should you be interested in either the lock adapter or a specific part from the Rally Kit, PM me.

    Hi guys, I just pulled the bearings out of the dakar front wheel and just wondering, has anyone just swapped out the bearing to fit the yz axle and made up spacers to center the wheel and take the bearing seal?

    Last time I looked around there were no bearings with the right ID and OD to mate the BMW hub and YZ axle together

    You need to get a aftermarket top clamp and run a sub mount. I have one for sale that works with a BRP or scotts top clamp.PM me if you are interested. The clamp can be found on ebay. Then you need a 2011Y Z250F stem mount. After that you have to weld a small cross bar on the frame. Here are some pics of how I did it.

    I'm interested in placing an order with Hawk Engineering for the "Radman" designed Yamaha axle kit. After talking with them (Hawk) yesterday I was told they would need an order for six kits...

    Anybody interested?

    The kits are not cheap but if you want to use your BMW OEM parts then the price is the price. PM me if you're interested.

    I'm interested in knowing how many of you shortened the stroke on the Yamaha fork?

    By how much did you shorten the stroke, 1" or more?

    And for those who didn't shorten the stroke, have you had any problems?

    I have the full length but also ordered a longer rear shock to match (about $800 from Wilbers). It all depends in what you want, if you want the ultimate dirt capable F650 go for full stroke and custom shock, if you just want better front suspension (much much better than stock!) get the forks shortened.

    you can also use shorter dog bones with a standard length shock to raise the rear.

    House of Horsepower was working on a full fork suspension upgrade kit. Has anyone gone this route?

    I have spoke with them about it and apparently are very good. Should be ready to sell in a few weeks they said. So I'm waiting to see...

    Anyone got an old fork slider to sell now?I Need a left side and a brace as I crashed while riding in Columbia today. Back in the states for Christmas before getting back to the bike to head hopefully down to Argentina. New ones are horribly expensive and I can buy a used one from the uk but worried about shipping. Anyone want to sell me one?

    I have a 2004 f650gs so I am guessing its the same as the Dakar?

    Intrigued by what the fall was for damage like that to come about, get well, hope the pain does not last long

    Straight into the rear of the car. Breaking hard, their paint is all over my front fender and then I fell to the left I think the bike skidded into 180 as I was facing the other way when I go up!

    Sorry to hear your misfortune, it sure put some pressure on that RHS axle lug, that is the revised stronger one too, the earlier one would have broken open the fork wall. Twisting motion breaks the fork brace so it has gone onto full lock and twisted though the braces can break under heavy usage so there may have been prior fatigue to the brace

    Have the steering yoke checked in the repair I know the lower yoke can twist with less force than one would think it needs

    Just for laughs I ran an early R100RS into the rear of a mini van and bent the sub frames of the mini but was able to ride the 100RS away for repairs (complete with broken bone in my foot) while they had to tow the mini away.

    Recover, you have to keep up the good efforts on the reputation of Oz riders

    Thanks Wayne, ok. What part exactly is the ' lower yolk'. I am working on logistics to ship my bike to Bogota and locating and buying the bits I need second hand in the US get them over Christmas and return to fix my bike before new year. So if there is a place I can look to check now to get the ball rolling all the better. Thanks for your help.
