Or $250 (something like that) on eBay right now...
The G450X has a bit more travel than the G650 so you will probably want to shorten it like most other options..
Edit, just looked them up, $1175 per leg? Did I read that right?
Only about $100 more than Xch fork legs then.
I took the wheels off both today and there are some complications including slightly different fork sizes. Bummer.
But still, the eBay find got me all stirred up, but I have a question: Does anyone know if the bottom part of the fork can be swapped from one fork to another assuming the diameter is correct? Both are made by Marzocchi, right?
Thanks for you help.
I can confirm this for you in a few weeks, but yes it seems that is the case. Looks like Marzocchi made multiple types of this fork in different configurations for different bikes all based on the same platform.
I have a pair of WP 4860 and the lower Emig clamp waiting in my garage to get adapted to my '07 XCh. I contemplated buying the axel from them, too, but I somehow balked at the price... in comparison to the much elaborate clamp, I didn't think it was worth it. I plan to get the suspension shop fabricate it, but now seeing your ingenious solution I would much appreciate if you can provide some size details for the 3 components... I guess you are reusing the original XCh axel and made 2 pieces: a "shim" and an extension. It would be awesome if you can maybe share with us the fabrication details
You can buy an axel reduction kit for KTM,takes the axel diameter from 26mm to 20mm and use the original BWM axel,spacer and front wheel.
You also have to get the caliper hanger from a KTM 690 E or 950 super enduro.
They both have a 300mm front rotor.
Only thing is you have to machine down the thicker part of the OEM axel from 25mm to 24mm.
Takes a few minutes on the lathe.i
Then just install and go ride and enjoy.
I've read quite a few threads on X front suspension upgrades and I want to make it my winter project. I haven't decided on which way to go yet - simple upgrade in the fork legs to fit my triples to a complete KTM front end job as some have done, or something in between (like to accommodate low fender). In addition, I'm not sure if WP 4860's or Shivers are the way to go. My real question is - and I may have missed this somewhere - how can I know or be sure that the forks that I buy are close in fork length/travel/triple clamp spacing to my OEM legs in order keep things close (even triple clamp diameters for that matter)? I've read folks buying forks from KTM this or Aprilla that - but is there a WP or Marzocchi spec sheet that tells you exactly which bike model, came with what fork, and what the overall specs were so I know what to look for when it comes buying? Kind of a guide/spreadsheet, instead of having to look at individual bike/fork spec sheets?
As I understand things there are a series of 4860's and Shivers out there that differ based on the bike, correct?
Any help would be appreciated!
BTW - if you have a set that I may be interested in (or have a lead on some) let me know!:huh
I have a spreadsheet with a lot of info on the WP forks, which fork type came from which model etc and part No's and other info. The Airhead guys are using it to help with their conversions even though I put it together for 650GS perhaps it might help you
Thanks - looks like some useful stuff there - I'll be sure to dig into a bit more!
Appreciate you posting this..
Anyone know if the g450x front forks can be fitted easily on the x-c?
Sorry if this has been asked already...nothing came up on my search
Why would you? They arent much better.
But they probably drop right in at the top - not sure about the bottom end of the forks - if they match up
Anyone found preload adjusters for the OEM fork caps? Perhaps a swap from another bike?
Would Husqvarna SMR 450 Marzocchi Shivers work on the xChallange - either rebuild, or as a transplant ?
I know the 2008 -09 model has almost the same forks I have in mine now - 50mm marzocchi twin chamber forks. http://www.motorcyclespecs.co.za/model/husqvana/husqvarna_sm450r 09.htm (SMR had shorter 250mm travel). Thats a pretty extensive transplant - involving triple clamps and front wheel as well.
But Husky were changing forks almost on a yearly basis. Each year has different size forks. Not like KTM which runs the same size forks and triples in almost all their bikes for a decade.
They are from a 2003, which is using 45mm. I asked "The Guy from Hyperpro who should not be mentioned", who said that they should work (also he is also going to do the work).
I got them for 150, and I suspect that they will be used for a transplant, if not, I can always donate them to an xMoto owner
Oh him?? If he says it, then it will be true :)
Has anyone gone the route of just adding the hyperpro progressive springs to the stock forks? I know there is only so much performance to be had from the OEM set up but I don't have the time/energy to devote to a complete fork swap at this time and was just wondering if anyone else had gone this route and if it was worthwhile? FWIW I am 150lbs.
If you are 150 lbs the stock springs are probably about right. You might try changing your fork oil to 15wt and keeping the stock springs. When you buy the HP springs you will get the heavier oil as part of the package. At least I did.
IMO the real issue with the forks is the lack of dampening control. It's not just the separate rebound and compression but the poor performance of the stock valving (or lack thereof). That's why people convert to the Shiver internals or do the WP fork swap.
Thanks. I need to read more about the shiver internals.
