Hey guys, does anyone have any suggestions for the best place to send my suspension with having the 4CS forks? Ive read where Powerband and MB1 do a lot of these but I’ve never dealt with them. I’m a 200lb rider on a 15 KTM250SX so I’m gonna need springs and everything else. Thanks in advance!

Factory Connection did mine on my 15 Husky 125. Very happy with them.
Fast turn around and excellent customer service!

You only really have to choices of guy's that specialize in the WP 4cs forks!
That is Jeremy at www.MXtech.com & Adam Kreft at http://www.kreftmoto.com/
I went with Kreft after much research.
Go take a look at both of their site & call them, see what they have to offer you for your setup.

I just had my 125 with 4CS redone by FC. I haven’t ridden them yet, but can give you a report in a few weeks. I threw everything at them to make them better, so we will see...

Why you guys want to do the SSS conversion for the WP forks, it does not make any sense(Protune 1000$ with used parts and TBT 1700$ with new parts)?
You can get brand new Yamaha KYB SSS Factory fork from 17 Yamaha about 950$(or even less if you know friendly Yamaha-dealer), then you can buy from Technical Touch KYB WORKS KTM specific axle lugs and oil locks for around 400-500$(add 300$ bucks more, if you take new inner tubes as well, 450$ more if you take new innertubes with DLC coating). For 1400-1800$ you have brand new another fork that you can use and put the 4CS aside, then when you will sell the bike, just swap the crappy 4CS back and take the KYB for for new bike again, easy.
Yamaha SSS outer tubes will fit into latest KTM, you will have to use 0.5mm shim. If you do not want to use the shim just buy the Xtrig triple also from Technical Touch.
I have done SSS conversion few years back into one KTM, it worked good but it was no match to previous KYB SSS complete fork which I had in the same bike. I believe that flex characteristics is different KYB vs WP tubes.

If you have the money do the sss conversion this is the best option. I did not go that route, i went to ty davis he switches the compression to the lugs and the tops are rebound. This along with springs for my weight and valves turned those forks from horrible to decent but at $400 for everything it was worth it. I have yamahas with the sss and they are much better. All depends on what you want to spend. You can find used AER forks too. Those are much better then 4cs but you will spend about the same as the sss conversion.

Your local garbage company can put them to good use. My 16 Husky has them and have been revalved twice. Still like pogo sticks. Worst fork out there imo.

Billy at Powerband racing, do some research on him. Not disappointed with my 4cs at all.
Unleaded tastes a little tangy. Supreme is kinda sour, and diesel tastes pretty good.

One more vote for Corey at pro tune, but , if money allows, go with the dal Soggio sphere inserts. They are absolutely fantastic, imo much better than sss or aer.

Thanks for the replies and input. I just got off the phone with Billy from Powerband and he’s gonna set me up. Not going to do any conversions or anything.

Ditto on this kit. Installation instructions are included. Suggest installing new bushings also.

A year ago I had the SSS internals installed on my '16 FC450 at PDR.
Soooo NICE!
I just talked to owner Clay Olson that did the mods for me and he says no more need for the SSS
internals.
Race Tech has caught up and works excellent!
EDIT: I had the customized Race Tech Gold Valves installed at the same time as the SSS internals. You would want Gold Valves even if you were upgrading a Yamaha.

This is what I did. I didn't realize the SSS conversion was that pricy. The Dal Soggio setup is top notch.
