does anyone know if the bearing cups on the x-chal are the same diameter as on the f650?
I've been told there's even the same as those from a K100 or a BMW airhead.
I don't like the screws to adjust the forks. Anyone knows good and easy to fit 'knobs'? Would be so much easier...
i m also interested in this option...has anyone done this?
Everything comes at a price! I believe Wunderlich sell knobs for this very purpose.
Just wanting to know if there are any tricks about taking the forks apart to put new springs and oil in. Do I take the caps off, then drain the oil, and install new springs and oil. I've looked all over and cann't find any information. Anything would help.
Especially if it is easy-ish... Are people using the aftermarket Touratech springs? Does Ohlins make springs for these shocks?
Thanks in advance!
I put in a set of Wilbers. They provided instructions that gives the info needed. It required removal of the forks from the bike, taking caps off etc. Correct procedure to put in the right amount of oil and purge out air is explained. Hope this helps.
Hyperpro do springs for the XC as well.
Is there some kind of report of all these aftermarket springs? I really don't like the stock ones but have no idea which springs to get...
I have read a few reports and received info from owners who have changed springs on the XC. Most gave the Hyperpro a huge + for improvement while some other brands did not make that much difference.
Other than oil and springs there is not much else that can be done to the standard fork. In Oz Hyperpro front springs are approx $250 and the rear shock is $1650 (compared to the Ohlins for $760 delivered).
Might just do the front springs and oil first and see what the difference is and then think about the Ohlins.

if its only gonna take Hyperpro front springs, with a Hyperpro rear shock, to get my bike to do this.
then me thinks its money well spent.
I understand that many of you wanted to alter your front suspension. I would like to pursue altering the frt height (I'm 6' 1 1/2") and as I ride it feels like the bike is angled rear-to-frt. There is aprox 1in 4/64 of tube above the clamp. So what happens to the handling if I raise the clamp. Nothing in the owners manual about the tube height. I'm a newbe oh yea I weigh 225lbs. I see some have changed using risers, I have ABS and am not sure of my cable length allowance.
i've been playing with the front fork valving on my xc and have found there is a lot of potential with these forks (yes, i know it supposedly can't be done but by machining my own parts i can now make changes to valving/shims).
i've found the compression side really does nothing until you get through most of the travel. the rebound side has the control of both rebound & compression but the adjustment screw only affects rebound. by modifying the compression side i've found a lot more control throughout the range as well as the ability to have meaningful adjustments.
as i continue to test out the settings i will post my findings.
and we wait with baited breath.........
and orders and money.
here's a teaser shot showing some of what i've been working on:
Damn it man...that's 2 major upgrades you've teased us with. Are you going to sell this stuff???
Maybe if all the X owners chime in so evoluzione has some idea how many of us would be interested there might be enough of us to make it worth while for him to make a run of new valves for our forks ?
i hope you folks understand that we do a lot of development work that never turns into sellable products for one reason or another. in the case of the front suspension valving, there does not seem to be a lot of customer interest. also, there is the issue that we would need to do the initial modification to the cartridge (requires us to precisely machine the cartridge - if we just sold the valves and let the customer do the final machining and they mess it up, then they would need to buy new cartridges). once we do the modification, the customer will be able to change/adjust shims by themselves.
the bottom line is that if we had enough interest to machine 25 sets then it might make sense to us. i would guess that the cost would be $200-$300 a set including us doing the intial modifications to the cartridge.
I'm IN for that amount.
