Has anyone done much experimenting with different maps? I see the Chavez map just adds fuel and no ign changes. I haven't played with it yet but curious how useful of a tool it is to alter power to your liking... Once you open up the intake and exhaust is it advised to add fuel or was that kinda built in with the base setting...? Just got mine haven't ridden it yet, super sweet bike and can't wait to rip it!

I have played around alot with mapping and actually ended up back at stock. I'm running opened up air box and Ti6 exhaust. I feel like the kx app is a bit of gimmick compared to the yamaha one.

Anyone know how a PC ti6 pro sounds compared to stock?  Is it much louder?

I have a T-6 on mine and it is much louder.  

Yes that what happens when you have freeier flowing non baffled exhaust.. they will always be louder

Thats a no brainer bro.. surely to be expected, not sure why it’s even a question?

The KX app is super easy to use.. not really a gimmick since it’s basically a carbon copy of the Yamaha one

I agree that the app is very easy to use and very similar to the yamaha app. Where it differs is the actual effect it has on the bike. Changes on the yamaha app are very noticeable, not so much on the kx.

Has anybody heard any news of an SR coming out for 2025?  I'm loving my '23 SR and would love to replace it with a '25 SR. 

Also, to RCMXracing I have owned an 07, 15, 17, 19, 21 and 23 KX450 and all have been super reliable.  The only issues I ever had were the chain guide wearing out quickly but even that was fixed with the '19 generation.  The 19 was a huge step forward for me as I could never come to grips with the air forks so stock to stock it was a huge upgrade.  I have over 55 hard hours on my bone stock 23SR with zero problems.

KBMM is in a few weeks. That stands for Kawasaki Business Management Meeting. That's when Kawasaki reveals the 25 line up to the rest of the company.

Anyone seen an available airbox wash cover for the TA power flow setup? I talked to TA about a few weeks ago and they said it should’ve been late April and gave me a part number (160135) but I haven’t seen it available yet.

Maybe the "Breaking News" post on page 52 of this thread will help explain certain primate behavior; it's certainly a pattern.

I noticed you had Precision Concepts do your suspension. I had them do mine on my 21 kx450 set up for the west hare scramble series and really like it. Thinking about pulling the trigger on a 24 and swapping out the fork internals with the PC stuff I already have on my 21. Have you talked to Bob Bell about what changes he's made to the valving between the previous gen vs this new 24? Just curious if they're similar or if the set up is completely different for this new chassis. I know I'll have to have the rear redone, since the shock is completely different, just wondering about the forks.

Everyone is waiting for that wash cover, it's been a little frustrating.  No ETA on this part either.

We had one from Twin Air to test back in January but we had to give it back to them.  You guys who own a 3D printer, can you get on this?

Hopefully they get one ready for purchase soon. I’m a little paranoid about washing without a cover.

Completely different set up. I asked Bob if I can run my other forks in a pinch & he said they will bolt on but are set up different. 
 

The 24 is definitely a lot different than the previous gen. Overall seems good. I’ll post a further report after a few more tracks this weekend! Cahuilla was a little ehh today. Made several adjustments that all helped. 
 

Brembo brake is absolute dogshit 😂😂 for my last moto of the day I put my old brake set up on & it felt much better. I thought Brembo was supposed to be the cats ass? Asked my buddies what they thought about their brakes & got a similar response (don’t work, frustrated)

Totally agree on the Brembo, I felt like my 22 had better stopping power.

The brembo is more progressive braking..prefer it versus instant lock on

That sounds really strange to me.  I feel like the Brembo brake is one of the biggest improvements when I compare my ‘24 to my ‘19.

I love the brembo front brake, while it’s not near as aggressive as my 21 kx I had was, I like the progressive feel of it at the lever. I’m more confident using it in corners and other areas cause I know it’s not gonna just spit me on the ground lol.

i am the exact same way. i thought i didnt like it at first, but now i actually really enjoy it. Linear and just feel like i have more confidence using more front brake in corners. Honestly might swap out the hydro clutch to a brembo as well.

I agree about the Brembo being more progressive, I just wish it had more stopping power. My 22 could stop faster with less input at the lever, I'm just nitpicking though.

I’d recommend re bleeding before your next track day. Sometimes new there is air in the line. 
 

the 22 front break would take less input on the lever due to it being less progressive and touchier 

in my opinion the Brembo actually has more stopping power just way more linear. Essentially you just gotta pull the lever more lol. That’s what I felt anyways 

 

just my .02

My 13/17/20 models you’d have to tip toe around the brake lever, once in a high speed braking situation it threw me to the ground

the 19-23 models you’d  had to go easy on the lever, very minute pressure or it would go full lock on

at one point ended up taking the pads out and cutting grooves in them to reduce the braking surface.. it did very little to resolve the issue other then using a softer braking material 

 

im actually loving the feel of the new Brembos  it fits my style of riding with its more progressive feel

Like you guys have all said, the Brembo is less touchy and has more "feel" at the lever.  It's very similar to a Sram/Shimano comparison in the mountain biking world.  If the KX Brembos are like the Austrian bikes, just like Victor said, they may need bleeding early on.   I've seen may Austrian bikes in the last 3 years or so get mushy brakes with very little hours.  They are always much better after a flush and bleed with high quality fluid.  Pay particular attention to tapping the upper banjo to release micro bubbles as the Brembo banjo is more prone to this than the Japanese brakes.

I have ridden ktms the last 10 years and I think brembos is crap compared to the nissin brakes. 

You have to push back the piston in brembo caliper before every ride and always have fresh set of braking pads in there for the brembo front brake to work ok. 

The nissin got much more feel and braking power using only one finger.

I did bleed the brake after my first moto. it was immediately something i noticed so bled it with no improvement. I will put it back on & try to see if i can get the feel of it. I guess it's possible i'm not pulling it in hard enough. I probably have a very light touch on the brake lever due to riding the previous model for 5 years. No idea. 

I'm heading to pala today but i just brought my 23 to get a good day of riding it. My shock spring was sprung too stiff (not pumped on that but overall happy with my suspension guy on my other bike so we're gonna swing by after & get a lighter spring. bummer as i was wanting to get more time on the 24. Maybe get back on it for Sunday. Hope so. GH SUNDAY!

You shouldn’t be spraying water directly into the air box inlet, sure you’ll get residual water but it normally drips out the weep hole in the bottom of the air box 

 

several decades I’ve never had an issue with water getting in the air box during cleaning?

I personally don’t think you can get the air box completely clean without a wash cover. Sure you can wash the bike with a filter in, but you will never get the backside of the box clean with it in. For me persoanlly, I change a filter every time I ride. I think it’s cheap insurance to keep engines running longer and keeping valves in spec. So I might as well use a wash cover to keep my air box clean as well. To each their own
