Have a 24 450 with about 6 hours on it. Feels stiffer than the previous gen, but not as stiff as a Honda. The suspension has good damping for normal track stuff, but lacks a bit of comfort compared to a revalved setup.

It's crazy how different opinions are on the 23+ chassis. Some say it's too rigid and some have no issues with it at all, i peronally love my 23 350sxf. I do have kyb forks on mine but i also didn't mind the stock forks. I will say my 45hr 350 with kyb forks feels more plush than my brand new 25 150sx.

Yeah i definitely agree terrain makes a big difference, but i ride mine on everything and i still dont feel the harshness. Has to be the kyb's even though i dont mind the stock forks. I was a little shocked with how harsh the 25 150 felt, not harsh chassis wise but through the bars.

Lots of offroad guys with the 24 frames are removing the upper frame/engine bolts on both sides. I removed mine but haven't ridden the bike yet, hope to try it this weekend.

wasn’t that just people being stupid after the photos of mannys bike after erzberg? didn’t the bolt just fall out?

I know a couple guys that have done it on 23 and 24's and said it works. You can also buy the power parts hanger kit from AOMC or the 25 hangers. Removing the bolt is free.

I did have a 350 sxf 23 sold it because the chassie sucked with braking bump absorbtion.. the thing felt harsh no matter how many settings and different conevalves i tried. Also rode with the stock fork ofcourse.. 

Bought the 25 hoping it would be a lot better but to me it feels very much the same.. tried conevalve and conevalve air and stock suspension and 10 different settings with the conevalve fork but it never felt as good as I like it to feel so i sold it yesterday. Done with KTM now.

I’ve ran cv and currently 6500s. Both were night and day better than revalved air, but still pretty rough towards the end of the day when the track is dry and rough. In the process of doing a kyb conversion mostly out of curiosity

Out of interest what bike did you go back to ?  Kawi, looking at your avatar ?

I had a 22 350 sx-f, and really enjoyed it once past the 5 hour mark.

Now on a 23 crf250r, and i find it horribly harsh on hardpack braking chop, even after a revalve.  Also a 250f is just a bit light in power department for my liking.

Have been tempted by the amazing deals available on 24 model Austrian bikes at the moment, but i am very sensitive too and can't stand a harsh chassis, so have held off on pulling the trigger.

Still good deals available on 24 kx and yz450s too... can't make my mind up...

Just wordering what terrain you ride? And did you try any suspension other than conevalves and stock? The conevalves i have ridden seem alot harsher than my kyb's.

Man that sucks.  The braking bumps beat me up too on my '23 350.  No matter what I did with the air fork it didn't get better.  I had JBI do a 6500 kit for the forks and I installed the '24.5 motor mount and hardly feel them anymore.

I got a kawi 450 -24 with JBI pro revalve kit and I love it.. feels much better than the ktm pretty much everywhere. The only thing on the ktm that is better than on the kawi is the airbox/filters. Ktms airbox is larger and easier to see whats going on. 

Got 32h on my kawi now and have compared it on the tracks back to back with the ktm and I wont miss it 😊

It just shows we are lucky we have so many options to suit what we like. Im the complete opposite, had a 24 kx450 and 23 ktm350 and feel the 350 is better pretty much everywhere.

When you go from the 2019 thru 2022gen, the 2023 sseems really stiff.

Then you ride it and get used to it and set it up.

Then you ride old one and you wunder how you rode that bIke given its too soft and over fforgiving

Here are the must haves in my opinion.  Yes, you can do more if your budget allows but these items will do the trick.

1)  23.5 Ride Engineering or other triple clamps with Rubber bar mounts of some sort.

2)  Motoes 10 down and 10 back footpegs unless your short then 5 down 10 back.  

3)  Ride engineering or other progressive linkage

4)  Steering damper from RE or Factory parts.

I found that running my forks almost flush helped a great deal take pressure off the frontend and made the bike feel very good in the hands.

Just ride the fuckin thing jesus. You're not going to make it a 25 chassis by drilling holes in the frame.

Hey there vital keyboard tough guy, I’m pretty sure I can make it handle better and that’s the entire point of this post, not sure what value you bring to the table but I assume that’s a direct reflection of you in life in general.  Thanks for your help much appreciated.

Its your bike make it yours. Opinions are like A holes. I've got a 24 and have WP Pro components. Had to have it re-valved 2x. Its better.

I'm in this same boat. Braking bumps wreck my wgeld on my '23. I do have the KYB conversion. I'm admittedly bad at bIke ssetup though. I just nneed to keep wworking on it. Lately I'm hhaving trouble wwith my front end climbing out of the rut when i exit a corner. Aanyone deal wwith this?

The best and worst thing i do when i think im having bIke setup issues is let someone alot faster than me ride my bIke. I quickly realise it's not the bIke 🤣

HA! Facts! I always come to my senses when I'm blaming my bike and thinking of throwing a bunch of money at it when I look around the practice track filled with dudes on the same bike ripping. Yeah, it's a me problem

I’ve ridden steel frame yz250s with 10 year old suspension fluid, undersprung, that have felt better to me than any bike I’ve owned and dumped money into. I try to not ride those any more lol

The best advice you can get on this is to completely ignore whoever gave you the advice to drill holes in the chassis. 

I highly doubt the holes near the shock tower do much of anything to change the feel of the chassis (looks great for marketing, though!) It's the tubing changes they made connecting that to the head tube that make the difference. 

What do you know?  It’s not like you engineer anything. 🤣🤣🤣 You only make the coolest looking triple clamps.

I am 6ft tall and when I got my new 23 bikes coming off of 22 bikes both 350s I noticed something odd in that I found it hard to go from sitting to standing.  I felt like I was pulling myself up by the handlebars.   Then I noticed my pegs felt like they were higher and more forward than on my 22 thus pushing my legs up to the point it became harder to go from sitting to standing.   Having the lower and back pets allowed me to feel good going from sitting to standing and I also felt better in my turns.   I used to enjoy my old Honda 450 back in the day because of that feel.   Also, by having those pegs it is my opinion that it took pressure off the front end and made the bike feel better in the hands also.   Most of my friends have those pegs now and enjoy them.

To the OP, there is plenty of comment that a lot of people have zero issue with the 23/24. Wouldn't you be best to ride it your self into the 8-10 hour region and see if it is ACTUALLY a problem for you?

Exactly.  I love the forks/handling on my 24 300 SX.

well I'm putting the bolt back in lol, rode about 40miles of mountain single track on my 24 TX300 with the upper hanger bolt removed and the bike seemed to lose its turning ability. No head shake, but tight trails the bike feel sloppy and not very precise as it was before the bolt was removed. Interesting to learn chassis flex in regards to handling but that feel wasn't for me.

I tried it on the old chassis and felt the same as well so put the bolts back in. Lol

The two strokes don't feel nearly as stiff/harsh as the 4 strokes. I don't know if it is the engine mounting location, the fact the lower part of the frame is physically different, or if there is more difference in terms of tubing thickness in other spots in the frame.

Yes mine did that when I first installed my 6500 kit.  Always on the exit too like yours.  I found my sag was way off (to much sag) and my forks were to soft.

On corner entry the lack of engine braking on a 2T allows the suspension to work over braking bumps. I’m not sure I feel a major difference beyond that, or just the fact that a 2t feels lighter everywhere.

Technique is a big part of that.

This is what I would try....I totally stand to be corrected by the "Vital Mafia"  Smile

- Drag the front brake slightly.

- Be less aggressive on the throttle.

- More preload on the rear spring and / or a click or two stiffer on the shock compression / a click or two softer on the rebound.

- Lower the forks in the clamps/increase rebound resistance on the forks
