REP has the 25 linkage, bolt it on and your problems will go away!!
Maybe....
Ive been back n forth with REP on this from the beginning. They were very helpful and put up with my multiple questions like pros with patience. A rare combination
.
They said there seems to be two camps on this. One type of rider is fine with the tall rear end and the other type wants a lower rear end. They said I seem to be in the latter camp AND the REP link actually raises the rear of an already tall bike another 5mm so not sure this is best route for me? . In my case they suggested shortening the shock to get the rear ridding where I want, then adjust from there. In my case ( with stock link anyway) that came to a 3.7mm spacer in shock lowering rear of seat about 10mm. Now I was able to run 105 sag and get 40mm free sag with the rear where I like it, instead of running 115 sag and 50mm free sag ya get from just blowing the sag out . Much better with the spacers now and similar ride height in turns as my 2022 SXF chassis.
This is the bang for buck "quick fix" with its inherent limitations in that ya still have a link thats a bit harsh in first part of stroke and a bit soft in last part .
They said I can run the REP link with the lowering spacers as well and gain the benefit of the steeper rising rate in last half of stroke that's needed BUT with the lowering spacers you've rotated the link a bit and will be giving up part of the less steep rising rate plushness in the first half of the stroke. Still some improvement over the stock link and I may ultimately go that route.
Perhaps important to point out... I suspect REP has valving front and rear figured out that will give a more level dynamic ride height on track with their link and get the full benafit of its profile but at the moment the 5mm increase in rear height their link gives has me a bit shy of shelling out a bunch to find out if I would e ok with that setup?
For now I have opportunity to test Luxon's soon to be released Knuckle that's also softer in first half and stiffer in last half. That arrived today and I plan to start testing this weekend.
Plenty of work to do for now ha
For those that went to 14 by 52 or 53 gearing, what chain length did you use and did it help free up rear end?

Reviving an older thread.
How are you guys doing with setup now? Curious what sag guys with the rep linkage are running on the 23/24. I’m running 109mm now with my forks on the second line (kyb cartridges) and can’t really get much front end feel/traction. Logically I would run less sag, but my rear already feels super high. Running a 4.9nm at 200lbs. Static around 38mm
40/110 most I know run.
I know some that also feel it is the rider cockpit that is off, not always the suspension or chassi balance. Keep forks at second line and raise the bar 5-10mm instead.
Sag at 40/110 you can also close the low speed comp on shock. That has big impact on front end traction. You can try go out on HSC instead if it gets harsh and stiff and to maintain balance.
You can also try dropping the reseervoir pressure to 8 or 9 bar. You will have to increase preload to get same sag. Increase of preload and reduce pressure will give your more front end traction but maintain balance. Higher reservoir pressure give a more diffuse feeling but slightly plusher ride. This is beside the point of keeping cavation right.
Also, running Xact Pro shock, it's easier to drop sag but still get good cornering and traction in front by stiffening/closing the high speed rebound at the same time. You lose HSR when backing of preload and using just the LSR on stock shock affects to much other areas.
Perfect, I will try that out. I was thinking I’d mess with the hsc next to see if that helps.
I’m also running 3mm preload on the forks, that’s the only preload I’ve tried since the conversion. I believe I was running 0-1mm on the cv and 6500s, so I may drop that down
KYB should be 3-4mm, don't dropp below that. CV/6500 built differently so they can handle it.
Go max out HSC, go in 5-6 clicks on lsc instead and try that.
Will do, I appreciate it
Any updates on how things played out after the recommended adjustments?
It’s been too hot in the desert to really ride, but I have been making some changes.
Recent shock changes : lainer compression adjuster and main piston, shortened shock 2mm (dropped rear of bike 5mm)
Still playing with valving on the kyb cartridges, installed Enzo spring tubes yesterday. Forks feel busy now and a little too soft in top and mid stroke, will be making adjustments to valving soon.
Overall the balance and front end feel are improved and I feel I can get the rear pretty good once I get to the track. One thing I’ve learned is what feels good in my local terrain does not translate well to Glen Helen. Like at all lol
Thanks for sharing your experience.
sorry havent looked at this in a while
Reading the above posts reminds me of the issues I had with getting comfortable on the new KTM chassis. Trouble.
IMO one of the biggest issues is simply the cockpit. The 2016-2022 chassis had a level seat with 103 sag. The new chassis has a stink bug seat with any reasonable sag numbers.
If I still had this bike I would seriously consider altering the subframe rather than trying to band aid the chassis to level with suspension mods/ adjustments.
I looked at this a bit before selling the bike and it did look possible. The rear of the seat will need to be lowered by about 10mm to get a cockpit similar to the 2016-22 bikes
BTW I have sense bought a new Triumph TF450 RC. Its basic layout/ cockpit etc is nearly identical to the 2016-2022 KTM chassis AND it feels very similar on the track. HOWEVER I would caution anyone thinking about these bikes. The reports are not good with all kinds of transmission/ ctutch/ etc issues in the motors. The chassis is trully great BUT many reporting issues in the motors. Mine came with wads of scotch bright pads, chuncks of O ring in the oil. There seems to be real QC issues at assemby and some metalurgy issues with shift drums wearing quickly on the 450s as well as clutch failures on the 250s
So far I only have 4 hrs on mine and its OK. However Im on the injured list so wont be able to comment further on it this season.
Something that may be of interest to some of you guys, I was doing a bit of research before I purchased some used Husky MX Tech Raven inserts and I discovered that the new CC spring forks they are using in the XC bikes are 10mm shorter than the current and older air forks.
Im now running these in my 23 300 XC, its hard to isolate the fork length feel from the new inserts but the front end feel is substantially better and I gave up no stability on 4th gear fast rough sections.
