I have a 24.5 KTM 450 Factory Edition along with my newest bike the 25 350XCF. With the CUO it is easy to dial back or dial up the engine response. If you ride more moto and are fast perhaps the 450FE is a better bike. If you like to do a light moto and more off road riding the 350XCF might be a better choice. I would have bought a '25 350XCF Factory Edition if it was available but I did not want to wait as KTM usually announces that bike in late September at the Ironman GNCC race. I really like the overall balance of Power/Weight/Handling in the latest KTM/Husky/Gas Gas 350 models. Here is a quick back to back ride on the 450FE and 350XCF... ua-cam.com/video/x7aT09zbyzg/v-deo.html

@@mxengineer1thanks for the quick reply. Most of my riding is single track racing in Texas and in the Rocky mountains 2020 300 XCW. I’m looking for light moto to stay in shape and Texas hare scramble racing. I think I’ll wait for the 2025 factory edition. Thanks again!

I am really enjoying this new 350XCF!

Yes - very tempting to try one on this bike.

Private trails

Wheelies are fun!

Thanks!

I've ridden a 2023 Beta 390 Race Edition and a 2023 Beta 390RR. The Beta 390's have a more full flywheel feel to the engine - little slower RPM build and the engine runs really well at low RPM. The suspension is woods focused setting so too soft for even slow Vet moto but works great in the woods (spend the extra money for Race Edition to get the KYB suspension). The 390 Beta is heavier than the KTM 350XCF and you can feel this weight statically and in motion. The KTM has a lighter feel statically and in motion and makes more peak power and the engine revs more quickly. The 350XCF suspension and chassis feel firmer overall.

Good question! The Akrapovic resonance chamber has about 25mm clearance to the bottom of the fuel tank and the guard is about 3mm above the chamber. Seems like plenty to me however the stock resonance chamber is way more forward and had a more than twice the clearance. I really like the quieter sound and spark arrester on the Akrapovic.

That’s actually more than I would have thought. Thank you for taking the time to measure that!! In my opinion, the Akrapovic exhaust is the best sounding one out there for the Austrian bikes. Keep up the great work on the videos!

Thanks!

I wish!

Yes I've ridden the Sherco 300 4-stroke...that is a nice size engine. Wish there were more OEM's making 300~350cc 4-stroke off road bikes!

True!

No QS on 2-strokes

I have a set of black WP CV spring forks (you call them Gen 1?) and a set of 2023 WP CV forks (Gen 3?) and a 2023 WP Pro Component shock ready to go onto the 25 350XCF. I want to ride the stock suspension a few more hours to really understand it and then decide if it needs re-valved or just go straight to WP Pro stuff. For now the stock suspension is exceeding my expectations - works really well. Wish my 24.5 KTM 450 Factory Edition came with these spring forks!

Thanks for the real world feedback on so many great bikes! I really enjoyed my 21 KTM 450 Factory Edition and it currently resides with a buddy of mine so I can still ride it and it gives me a great comparison feel to the 23/24 and latest 24.5 KTM 450 Factory Edition. I also have a 2024 Beta 300 Race Edition and it runs amazingly clean and smooth for a simple carb and mechanical power valve. New 23/24 YZ450F is a beast and with the downdraft intake revs like a 2-stroke - very fun but hand on! Gas Gas EX350...very nice!!! You will be impressed with the latest 350 engine. Get the map switch and CUO so you can dial the power up or down and minimize the engine braking. 350's are such a great combination of Power/Weight/Handling!

Quick shifter too!

Yes lighter weight riders are a great match for the 250XCF. I am about 190 lbs and love the overall combination of Power/Weight/Handling of the 350.

Yes and for 25 model year the settings were tweaked a little to account for the frame changes. These forks work great but for trails I open them up. Stock is C12 R18 and I go C18 R24 (a comfort setting).

@@mxengineer1 thanks for the info and great videos.

Yes the 300 smokers are so good on tight single track and the 350 loves the more flowing open trails!

Thanks! Those RB shrouds came off one of my 450 Factory Editions.

If you are moving and hitting bumps and sloshing the fuel around you can use basically all of it. If you jump on a smooth road section and cruise steady state you may use all the fuel that is held in the pocket around the fuel pump. I regularly ride with only 2" of fuel showing in the lower section but I keep the bike moving and that sloshes the fuel into the cup around the fuel pump.

Thanks!

See if you can get the updated 24 EFI map installed into your 23 350SXF - that might be more than enough of an update. Also you could get the 25 model year engine mounts and bolt onto your 23 model.

Have a 2023 SX-F 350 and it's definitely an issue for me at low speeds. Apparently mxengineer1 said there's a new map (his son got it on his 450 SX-F) that will help with flame out. I'm a "VET" rider in my early 50's and it's definitely much different than riding a 2 stroke (which is what I grew up on) at low speeds. Can't ask for anything more on a moto track though......WOW!

Hard to beat a 300 smoker for tight technical woods riding. I've not stalled the 25 350XCF yet but always have a finger on the clutch and have not ridden it in really technical woods stuff yet. Realize the 350XCF is a high compression ration high HP engine (MXA says 54hp) so making an engine breathe and run good at 13,000rpm+ does make it want to run at low RPM's. KTM offers the lower compression ration and lower power 350XCFW for the tighter more technical riding - much more stall resistant.

Roczen is such a skilled rider I enjoy seeing him racing on any bike!

350's are a great combination of Power/Weight/Handling!

Rider still 85~90% of the speed so Coop would be fast on a 125!

350's are a great combination of Power/Weight/Handling!

You have some great off road riding in BC! The handlebar/seat/footpeg relationship is tight on the Sherco models. The handlebar mounts feel close to the rider, the footpegs feel high and a little forward, and the seat to footpeg distance is tight.

No - just changed the preload on the stock spring. Honestly the 300RE engine runs so well and the power is so strong and smooth I am hesitant to change much.

Ohio. GoPro smoothes things out!

Cool analysis! I have the LITPRO on the 25 350XCF (which does not have hand guards) so if I got LITPRO for the 300 could do some analysis of the loop. Laptime is a variable to look at when riding back to back. The TX300 suspension (full Pro Components) felt pretty good to me last fall and earlier this spring but after spending so much time riding 4-strokes recently I may need to spin a few clickers on the TX300 to get it a little more compliant (or perhaps there is something to the updated frame having more compliance and tire contact patch feel)....maybe a '25 300XC would work better?😎

@@mxengineer1 ya the LitPro is the ticket. Maybe an iPhone with a GPS app like Gaia or other you could get stats from the same device on each machine. GoPro used to have a track option. I know every time I’m on my buddies 24’ fx300 I try to blitz him on the trails if I’m in front. Rarely works. I definitely feel faster with the 300 the more technical it gets. Fact is, when he’s on my 350 he pretty much blitzes me 100 percent of the time. I get back on my 350 and I feel slower on it, but it’s not the case.

Based on my CUO experience so far I don't think there is any change in flame out character using the CUO. I have not ridden difficult tight trails yet on my '25 350XCF. I will make a video comparing the "250F" map with the stock Green map on some tight trails and see if there is any difference in flame out.

@@mxengineer1 Well for full adjustments it definitely allows one to add more flame out, but there are ranges which aren't yet pssobile to set that make it run with less flame out. Just a map to change.

@@platin2148 Perhaps KTM will add more engine tuning options on future releases and updates to the CUO!😎

I had the 16 350XCF, 19/20 FX350, and 21 350XCF. My 21 350XCF with the myKTM connectivity unit and full Akrapovic exhaust had a very broad powerband (best of the previous generation 350 engines I had ridden). The 24/25 350 engine with the latest EFI map (better than the 23 350SXF/XCF map) and my '25 350XCF is the best 350 engine to date with very good low to mid power and strong mid to top power. This new engine very fun to ride and with the engine braking dialed back and easy enough to dial up throttle response for more low to mid power using the CUO I think you will find this latest engine a nice improvement over your 2018 engine.

@@mxengineer1 thanks for the great info on the 350's

I don't think the CUO has much if any effect on flame outs based on my experience so far. I've not stalled the bike on the woods loops so far but have also not ridden an super tight technical trails yet. I will make a video soon of slow technical riding with the dialed back "250F" map and the stock Green map. Flywheel weight should help on your 24 FX350.

For 2-strokes it would be a 300 smoker and currently I am torn between the Austrian 300 TBI models and the 24 Beta 300 Race Edition. For 4-strokes 2025 KTM 350XCF would be my Do-it-All bike (or Husky FX350)

Lol, you picked two bikes, a 300 and a 350. Now, which would you pick between them for one do it all bike?

@@PezRacer 350 as I don't do much super tight woods riding and the 350 4-stroke works better on the moto track for me

Don't worry about lap times - pick the bike you want!

I've ridden a few 23/24 350's (SXF and FC) models back to back with my 24.5 KTM 450 Factory Edition (new chassis) and '25 350XCF and perceptive riders will notice better lean angle traction and little more comfort (mostly from the rear) on bump impact and hard pack choppy conditions on the updated 2025 chassis. For me the chassis changes are noticeable and make a difference and are worth the extra money. Less picky riders may not notice any difference between the 24/25 models. There are some decent rebates and deals out there on 24 model Austrian bikes so perhaps take the savings and have the suspension dialed to your liking and buy the 2025 engine mounts and be close to the 25 model?

@@mxengineer1 I am a very picky rider, and I am on bike number 50ish now. Not that I have had a lot of bikes, just been riding for 30 years. That is a great suggestion regarding the engine mounts. The rebates on 2024's have caught my eye. My son's 2023 handles infinitely better than my 2019. If I do not pull the trigger on a '24 with rebates, I will pick up a '25 in fall of '25. After thinking about it, sounds like the improvement of the '24 will be huge over my 2019.

@@jackieonassis7438 Fun to dial a bike in to your liking and when the price is right that makes the effort worthwhile. Being an engineer I am attracted to the latest design or "improved" design though newer is not always better and often times just different!

KickIn Roost MX!

Never enough bikes! Yes only 31 hours on the Kailub Russell 350 which I just sold to a buddy of mine

Man only 31 hrs on a 4 yr old bike ! Want to sell ? My 2024 factory sx has 50 + already
