Was curious if anyone has made something similar to this with a bigger turning surface and bigger flat head to adjust the rear shock rebound without dropping the linkage? This is what comes with the WP6500 dropins.7106A9CA-B7C9-442A-B677-9FF88436BE78

Not sure if you mean un bolting by dropping the linkage? If you do you can get to the rebound adjuster but taking the bike off the stand.

Lol brain fart. I spaced out and didn’t even think of that. Loving the bike, still getting used to everything coming from KTM.D333E5B6-5DB8-494A-82C6-97B21782DA3C.jpeg?VersionId=5fPkJTq

We are working on a tool for the rear shock rebound clicker and the compression adjuster on the forks.

Awesome. It would be nice to do on the stand!

Any idea if these peg pivot covers can be had anywhere? If I have one gripe about this bike, its the scooping effect the peg brackets have.

Seems pretty annoying they don’t have the same forks and front brakes as the 450, I was thinking/dreaming of a way to get one to match the 450 but the different parts is a bit of a bummer just for consistency feel.

Any secrets to dropping the shock? Will pull the swingarm and do bearings again if I have to. 25 hours in and time for a revalve… But I want to be lazy.

Loosen subframe and push as far to the side as you can with air boot still attached. Shock will slide right out.

Spend some time playing with the suspension before sending it in for a revalve.  The stock valving is really good and well balanced once you get the spring rates and oil level set correctly for your weight and speed.  I made a change yesterday that really made me happy.  I had originally set my fork oil volume at 370ml same as my ‘19 was.  I also installed one OEM optional stiffer spring in one side of the forks to get better holdup.  I realized yesterday that I never bottom my forks, so I wanted to see if I could get more comfort by lowering the oil level.  I took off the caps and poured 20ml out of each fork.  After that change I can honestly say that my forks just as (if not more) comfortable than the revalved forks on my ‘19.  I found myself standing up in more corners because I didn’t need to transfer weight to the front tire to make it stick.  I have the correct spring rate in the rear shock, so next time I ride I will work on dialing in the rear shock to try to get the same comfort level I now have with the forks.  The accessory engine hangers really help make the back tire feel more “hooked up” IMO.
All this talk about the KX being slow is nonsense.  My bike has a PC exhaust, the Chavez map installed, and the stock airbox opened up.  I’m giving up nothing to any other 450s anywhere on the track, including the start straights.  I’m really enjoying this bike!

I’d love to know if the ‘25 250’s are corked up with restricted exhaust and airbox like the 450 was.

Agreed, the stock valving is some of the best stock stuff I’ve ever ridden. It’s very good. I added 15cc of oil per side in my first couple hours on the bike to help with holdup. I did the X-Trigs and FCP mount kit, and this chassis rocks. The motor mounts help the back end settle in a lot, but the shock did wallow a bit more for me. Added some low speed and took away some rebound, and it was pretty good.


I’m looking for some more plushness in the initial part of the stroke. I bottom the bike every so often, but it’s very rare. Being 190 pounds, I’m on the edge for the factory settings. If I didn’t have the coin, I’d have no problem running stock stuff, but I’m loving this bike and I’m spending some time and money chasing a really great setting with it.

Go on the Race Tech spring calculator and get the right shock spring.  That was the first thing I did and don’t experience any of the wallowing you’re talking about.  I’m like 220 with gear, so I had to go all the way from the stock 5.5 spring to a 6.0 to get the static sag where it needs to be.  What does your static sag look like?

Rode the Chavez map at Thunder Valley yesterday and was pleasantly surprised with how noticeable of a low end punch it gave in combo with gutting the muffler and pulling the air box grommet. Loving this bike the more I ride it

JBI DIY PRO Suspension Review. 

Im a life long mechanic, small to heavy industry. Welder, machinist and fabricator. 46 year old A/B washed up weekend warrior that races sometimes. I've did race tech gold valve shock kits on vintage bikes, built a hybrid 94 / 02 honda shock for a 94 CR125 this winter, changed oil and seals in forks, thats about it as my suspension experience.

The biggest deal with the DIY kit or this work in general is clamping / holding the shafts properly and having some finesse. Watch all 4 parts to have a better idea what to expect or if you need a few more tools: https://www.ridejbi.com/jbi-suspension-showa-49mm-pro-fork-install-guide/

Before: 170 w/o gear. Stock spring rates, added oil to front forks 370cc total. Not bad but high speed chop in corner entry was sketchy. Tightened head bearings a little, helped but still twitchy. Put 12 hours on stock suspension, decided to do the JBI DIY because my local guy Chad that runs Total Control was on vacation then off to Loretta Lynn's. 

After: Damn, JB isn't playing around. I'm impressed. Everything this setup claims it does it does. First moto I cruised around did all the jumps riding at 80%. Very plush. Next moto I started pushing, there is a double that will turn into a "triple" bump when the track gets rough. Faster guys will just sail it past the downside and on the backside of that bump. 80ft maybe? Good test for bottoming. Handled it great.

Pros: Basically as advertised. 

Smoother fork feel over small bumps because of the improved JBI Suspension Showa Subvalve design
Better fork hold up during aggressive riding because of the JBI Titanium Leaf Spring Cup design
Smooth progressive fork bottoming resistance because of JBI Volume Spacer
The MOST fork bottoming resistance possible because of the JBI Titanium Pro Perch

Cons: Not really towards JBI. Rear shock spring rate confusion. JBI said I didn't need to change springs. 5.4 and 5.5 (stock) work within my weight. Maybe the spring rate is ok but I have never had such light preload tension on a spring before in my life. The collar is 2/3 threads from the top (last thread). RaceTech calculator depending on the variables is 5.3 to 5.4. 

The rear unloading off a bigger jump face will pitch the bike forward more than I like based off the "plush" setup from JBI, he includes 5 setups btw. Get this rear a little more dialed and I'll be extremely stoked.

DM any questions if ya got them.

I'm not sure about the exhaust, but the airbox is indeed different. Looks more open from what I could see.

How did you attach the tuber to the cage? Could we see that?

How bad is the vibration compered to the older model ? I have a 22 350 so I'm used to a little but my 19kx 450 had none that I noticed

Awesome . My last 450 was a SXF, 2018. Great bike but I'm loving this KX.

That's awesome! If I can get the bike torn down to get everything greased this week I am hoping to ride the new KX this weekend. I will stop by and say hello if I see you out at SFMX in the future.

I tell people this all the time. Stock suspension on most bikes is pretty good these days. At least do some testing and try to find something you don't like before sending it in.

So here’s my update so far. 

I’m liking the engine more each ride. 

I’m still tweaking on the suspension / balance. I took a half turn of sag out each ride and it got way better through bumps but stopped turning. 

Went in on shock rebound and that’s helped the rear through chop.


I just raised the forks from flush to the first line since it’s been washing in turns hoping to get the front bite back without losing the balance through the bumps. Also went in 3 on the fork rebound and added about 7ml to each fork leg.


Swapped the bars to husky bend as the oem bend was tearing my thumb up.


Other than these tweaks overall super happy and super comfy.


Just need to keep it balanced through hard chop into turns and get the front bite back.


I think I’m getting close and once it’s there it’s gonna be magic.

So where is your race sag/ static sag now?  How much do you weigh, and what class do you race?

Anyone else not able to open the Rideology KX app since it updated yesterday. Mine just sits on the open splash screen. Tried everything except deleting and reinstalling as I don’t want to loose my service history I’ve entered.
