I do love my '24 KTM, but this certainly makes me wonder about future bikes. Time will tell. (Dear Japanese manufacturers, one of you please make a competitive 350.)

Is the 25/26 kx450 much different from the 24? I’ve ridden my buddies 24 kx450 a bunch and I’m a little lost at the idea that it’s slow. I own a 24 yz450 and my preferred map is the “hard hitting” map, so coming off my bike and riding his kx450 you’d think according to the bikes reputation it would be a huge difference. Don’t get me wrong, it’s a very noticeable difference between the two, but just because it’s noticeable doesn’t mean the kx is slow. That bike absolutely fucking rips! I legit jumped on his bike this past...

I have the Luxon knuckle and link on my 23 350SXF. It’s been a while since I installed it so I’m fuzzy on the A to B comparison but I do remember it making the rear feel more stable accelerating out of corners and it helped with bottoming resistance. I backed off my high speed compression about 1/4 turn when I installed it.

Have too much stuff to do and didn't have the time to dedicate to do the testing and dialing in.

I know this is a Luxon thread but I second the REP link. I installed it after damn near giving up on the +23 chassis. The best bang for my buck on my '23 KTM 450, hands down.

I realize you are asking about the Luxon but just put an REP on my 25 Husky. Very happy with it as it keeps the rear from any unwanted sudden kicking to the side when hitting a single square edge at speed. That was my person issue.

I installed the Luxon knuckle on my 2024 350sx-f and it definitely smoothed out the harshness of acceleration chop. That was my biggest complaint with the 2024 chassis - when I would ride my 2024 kx450 back-to-back with the 350, the KX was much more comfortable on hard edged acceleration chop. The Luxon knuckle significantly improved that area on the 350sx-f. I had to adjust clickers slightly (backed out LSC and HSC to compensate for some kicking going into corners), but otherwise I did not have to change the rear spring rate. I also have a 2024.5 Husqvarna FC450 Rockstar...

I think a lot of what determines someone's satisfaction with a modification is their expectations. It sounds like you have the right mindset and I hope you will be satisfied. To be fair, I should also mention I have another riding buddy who did the XPR 2nd injector on this 350 and he loves it...go figure, lol.

Can’t speak to the dual injector on the 350 but we did install the complete XPR setup in my sons 250f a few months ago and it was well worth it. Easy installation (air boot swap being the worst part and even that wasn’t bad) and as said above just get yourself a crimp tool. The detailed instructions are very good. They do recommend a gearing change and race fuel for maximum performance so take that into account as well. That being said we’ve noticed no difference or loss in running Sunoco 91 ethanol free. I would think if your...

I did the dual injector on my 2025 350 and love it. The bike is just better all around and just seems even easier to ride. I had the CUO prior and its night and day difference. Really cleans up the decel pop on the bike as well. Super easy installation took maybe 30 minutes of me just goofing off and making sure it was installed correctly.

Just for some additional feedback and consideration, my buddy just installed the XPR dual injector kit on his 2025 KTM 350 and was not overly impressed. He liked it and thought it was slightly more powerful, but was pretty adamant that it wasn't worth the cost. For context, he rode my 2024 KTM 350 with a CUO unit (most aggressive map, engine braking turned all the way down, and throttle response 3 out of 5) and a 2024 Husky 350 with just a Vortex on the same day, back-to-back-to-back. In my opinion, that is the best way to really determine...
