Yamaha forks on a BMW F650GS Dakar

Got alot of interest on this so ill try and post what i can remember about doing the upgrade. For starters heres a pick. The forks i used were off of a YZ426f, came with triple clamps, brake caliper and then picked up an excel wheel all for 250 bucks! Put in a heavier weight oil and then the heaviest springs i could find for the forks, new seals of course. The main two issues i remember having(did this last winter) were i had to machine the stock yamaha steering stem down about .010" for one of the bmw steering bearings, the other one fit like a glove! Also i had to trim the inside of the fairing so i could swing the forks without rubbing anything on the inside, and i also think i had to do somethin for the fork stops to work also. But let me know if you have any more questions and ill try and get some better picks once i wash my bike, its covered in a pile of mud right now! But i measured the weight difference of the two it was about 15lbs savings, the new ones were a bit longer then that dakar forks, but handles like a new bike now, and the front end feels so light and no more bottoming out!

Skibum, if you use the Yamaha bearing kit, you dont have to machine the shaft. The BMW, and Yammy have the same size outer cup diam.
I used the Yam bearings on my GSPD conversion, and the GSPD has the same bearings as the 650GS/Dakar.

Interested in the actual difference in length and also the size of the disc rotor.

You have not mentioned the upper fork yoke & whether it is the Yamaha one.

How do you find the braking performance compared to the BMW disc & rotor

You use the upper and lower Yamaha yokes.
Not sure on the 650, but I use the BMW wheel and brake on my GSPD.

Now this might warrant me to keep the Dakar. Tell me more about the way it performs, does it not make the front end to light? The KTM640 is very twitchy over rocky terrain, where the Dakar normally just plough through, yes, I know it's fronts are rubbish, but it does work there for some reason.
The only problem would be to mod the ABS ring and sensor on the ABS bikes.

Did you also fit different handlebars and did you had to do other mods to the switches and throttle?

Hi, what I would like to know if you tried using BMW wheel set, and if it would fit, and why you went with the yammi wheel set?

I'm looking for a set of front forks for a 01 DAKAR.

I thought this would be a good place to post.

any idea if the newer 04 forks from the wr bikes would suit or would they be too big for the bike and the parts?

There were a few guys that used the 48mm / later model forks with no problem. the issue for me seemed to be that they were always more expensive.

Well, it took me months and months, but I finally got around to doing something about my sidestand today.

Marking:





Cutting:



New piece (about 7 cm of extension):


Ready to weld:


I'm NOT good:



Coat of primer


Coat of black enamel



Now I have to wait a while before reinstalling it. My bike should finally have a reasonable stance on the sidestand again.
