A few comments and questions...

Could you specify which KTM clutch? Is this something you've done?

Has anyone installed an Akrapovic system and if so did that help smooth out the engine's hit (per Keefer)?

Dominus sells the Twin Air tab and 2 special screws in a kit https://dominuscorp.com/catalogsearch/result/?cat=&q=ta152227bracket++TA152227bracket (FYI...they are on Hookit but they charge $14 to ship it!)

Thanks for the info on the DT1 filters. I'm going to try one. Seems like the Twin Air filter just doesn't fit well on the stock cage (small)

What about the new FCP steering head bearing kit, anyone tried that yet?

Mine has about 10hrs on it and I'm starting to feel more comfortable with every ride. Basically stock except for 14/52 sprockets and RT Gold Valves in both the forks and shock by Levi Kilbarger (Bonzi Suspension).

Appreciate this thread and everyone's comments!

 

For the price of the Akrapovic get a vortex ECU mapped by twisted or someone similar. You will find much much better results for what you are after. Then when you want to add the exhaust they can remap it easily to make it deliver power how you want it. 
 

Exhaust while flashy is basically the same as new graphics. The ECU is a real upgrade

I have always asked just KTM sx 450f clutch kit for my understanding it been same now many years. 

I have FCP steering bearing kit but on my other Honda crf450f bike. Takes out nervous from steering and bike leans in corners better in my hands and follows ruts great. Im not pro just active veteran rider. Difference to stock was so big that I had to move forks up in mounts(1-2mm) and run less sag 106mm -> 103mm and took out some comp clicks at front fork as well. Been running last two races with it on sand tracks and happy with it. On my Yamaha I use NuAxle adjustable offset axle(I run 23.5 offset usually) that will do same thing but FCP kit feels better on corners. Negative thing about FCP is difficulty to test stock vs FCP angle because it uses own smaller bearings so you would need second triple clamps for track testing with stock bearing. For tight hard pack tracks stock triple clamps with stock 22 offset works great both Yamaha and Honda. FCP offers also steeper head angle just by turning spacers opposite side but I havent tested that option. Uploaded video about installation on youtube just search FCP Race Cups.

Anyone trying the FCP head up adjustment yet. Very interested! I think a bit slacker head angle would be a great adjustment on this bike!

I posted about my testing with FCP on my Honda CRF450 and I think will do pretty much same for new Yamaha.

Where did you post or what did you think? 

I understand the idea behind reducing the head angle, just looking to see how the feedback is on Yamaha and if anyone has ridden it.

Keefer race cup review:

https://www.keeferinctesting.com/fcp-race-cups/

“I get less head shake and the YZ450F feels more planted to the ground when straight or under lean (on or off throttle). These 20 degree offset races do make the 23/24 YZ450F corner a little slower but that is what I was looking for”

Reading Keefers race cup article it feels like running a Precision damper gives pretty similar results without losing the tighter cornering of the stock races and stock 22mm triples. 

I know dampers aren’t used nearly as much for moto as we do off road but adding the damper has been a big benefit for me and the bike is noticeably more steady in ruts and off throttle. 

Not saying one or the other (or vs 23mm clamps), just adding some feedback.

To me, the damper would just be a bandaid. But I understand your thoughts on not changing the turn character.

I’m interested in trying but haven’t dropped in on the cups.  I’m currently on the 24mm clamps which I like. Keefer commented on IG that he doesn’t think the bike needs cups and clamps, so I potentially have a lot to test!

I dont think damper would help and needing different t-clamp offset or cups depends where you ride.

Hard pack or slow tight tracks stock is working but when you go high speed or rough sand tracks more offset or cups will help alot. Of course you can do other things like shorten rear shock or drop forks low and run them with harder springs and so on.

For me and tracks im riding both Yamaha and Honda are feeling better with offset or FCP cups.

I think all the NGPC and Worcs guys are using dampers and mostly Precision now. So it may be more of a necessity than a bandaid, but either way it helps with with the wiggle and the steadiness that lots of people seem to be calling out on the newer frame.

I’ve been running for district 36 and sprint enduro stuff and thought it would feel odd when I got back to the motocross track, but I actually like it better.

For sure, lots of options and different ways to go about it. Dirt, track type and speed will all play a roll into what’s best for the rider and bike.

 Damper can help with some things, I guess just not really what I’m looking for riding MX track. Totally understand the GNCC or dez guys on it!

Save your $ on new mapping, use the free Magic Map (keefer website) or online. And chx gearing to 14-52 (stock 13-49)….you will love the smooth power plus relaxed chasis / suspension (from 14-52)

Since the this generation YZ450F has been out for a while now. I'm wondering what peoples hours and maintenance levels are at? They pushing 100+ easy on stock OEM parts, oil changes and valve adjustments? Is the engine trash at 50 hours and needing top to bottom rebuilds? Crank exploding in 30 hours? Or are they simply work horses that never die?

I've heard mixed stuff from a lot of people, so I wanted to ask ya'll. Either way I'm loving this Yammie.

I was getting worried about the seal with the stock setup.  I could imagine it pushing past the seal so my buddy did this up for added security.  Good setup.  I would use grease on the seal.  I feel like i'm performing surgery every time i take it off with the fear of dirt dropping in.

It's a PITA but laying the bike on it's side against the stand when pulling the filter helps a lot. If you use the power flow kit and you do drop dirt it lays right on the side of the boot rather than going down the elevator.

I've had my 19, similar filter design, for 5 years and 150+ hours and have never done this. I just pay attention while removing the filter and if anything falls off so far it's always been caught by the backfire screen. Never had to remove the screen to clean anything, and I ride in dusty clay and sugar sand 70% of the time. The amount of sand in the bottom of the sink when I wash my filters is always surprising 😂.

I’ve had the 23 and now I have the 24. Came of a Honda but I was tired of the rigid feeling that bike gave me. This bike gave a lot of comfort back! (Maybe I will be back on red if the 25 is better…) Now about maintenance. On my 23 I had a broken piston pin at 20 hours. Therefore I changed my piston at 15 hours with a new ProX. On my Honda’s I did never a top end… Rode one year (max 100 hours) and sold them. Crank is ok, but I recommend using 10W50 because it has a plain bearing. So far I didn’t have any failures. My 23 had 70 hours and with my 24 I’m currently at 30 (bad weather here in Europe 🥲). I get about 20 to 25 hours out of my clutches. Then I get a little bit of a slipping feel so I change them with ProX. I will be trying a KTM clutch pack soon. Stack height is pretty important with a Belleville spring so I have to figure that out first. Overall a reliable bike I think. Shit happens with every brand….

Power flow kit does away with the screen.

There is no screen permanently attached to these new gen bikes. The screen is part of the filter frame and wouldn’t catch anything when pulling the filter off the bike

still diggin it. Todays track was very rough. Hard pack chop for days. Bike handled it pretty well for being under sprung. Could definitely feel some sharp edges today. Put keefers recommended settings in but a couple clicks stiffer and dropped the forks to about 2mm. Seemed to help. Pardon my vet whips. Lol.. kiddo is just getting over mono we found out but she had fun today too!

No, you need the 14-17 one. It only has one alignment mark for the axle block, easiest way to tell.

Yamaha should make 14-17 type swing arm for 2025 model as every team are running longer ones.

Without reading back through everything, didn't you try this? Was it worth $100? If i recall, didn't you swap back?

I’m still using it. But you need to have a new chain slider every time you replace the chain because I wasn’t able to run it all the way back last time with the used slider. It does take away some adjustment life, I reached the end before my chain and sprockets really needed to be replaced. Plus you need to go up one on the rear sprocket which helps with 3rd gear anyways.

The new 2025 was revealed. Looks like a lot of new same changes on the chassis but still the same frame. If we are lucky most of those parts we can just toss on our 23-24. New engine mounts for stability, new footpeg brackets, and new rear linkage but on the same shock are already things I'm planning to toss on my 2024 if they all swap over.
