We just got our first chance to ride the 2024 KTM 300SX. We knew what we were getting into; we had a fair amount of time on our 2023 version and it never stopped impressing us. Prior to last year, KTM had never produced the 300SX for the U.S. It was up to the buyer to build it up from a kit or a modified off-road bike. There were a bunch of riders who attempted to race the 300XC in motocross, but it wasn’t a good fit, particularly with the Transfer Port Fuel Injection that came along in 2018. That made for a smooth off-road power delivery, but it wasn’t barky enough for MX. Now KTM has a whole new two-stroke engine platform. It has electric start, an electronic power valve and throttle body fuel injection. All that stuff has been seen before individually, but with the 300SX KTM integrated it all in a way that we haven’t seen before. The bike’s CPU controls everything including how far and when the powervalve opens. That’s never been done before on a production bike. Last year, the chassis was also updated to the same general specs as the four-strokes, meaning it’s a little more stiff and has more anti-squat tendencies than the older frames. The suspension still features a WP Xact air fork in front and an Xact shock in the rear. The brakes and hydraulics are still Brembo and Premix is accomplished the old-fashion way; you mix the oil and gas yourself.In case you haven’t heard, this bike is insanely fast. Technically, the fastest of 450s might make more peak power on a dyno, but that’s just a number. On the track, the 300SX feels faster than any of them. It has more to do with the way the power is delivered. Down low, the 300 is smooth and runs super-clean. If you have good throttle control, you can actually ride it in the zone below the powerband and turn in respectable lap times. But the real power starts in the middle and hits pretty hard. Modern four-stroke riders might not be ready for this. Most have grown up in the era where smooth power deliveries have accomplished miracles in disguising and making power easy to use. The 300SX has an element of that-it certainly is easier to ride than a ported and polished 250 two-stroke from the old days. But it’s still harder to control than a 450. On the other hand, it opens up options for different riding techniques. Almost all 450 riders have learned to do all their hard braking with the clutch in for fear of stalling. With the 300SX, you can brake hard without touching the clutch, and then roll-on the throttle old-school.

WOW. I've owned a '24 since April, and I couldn't DISagree MORE with a lot of what these guys said about it .
Firstly, NO it doesn't ride like it's got an afterburner. Especially for a 2-stroke it rides pretty damn smooth(you can '4-stroke' your way around tracks in 3rd gear without needing to fan the clutch if you want). I'd equate the pull this thing has to that of my 350(I have a Vortex ECU and run T4 simply cuz Kalifornistan gas sucks). The new KTM 450's are quicker and faster than the 300, and if you're unable to tell that when riding 'em you have no business 'reviewing' bikes professionally. The 300 has around 55hp stock(a smidge more than a stock 350, and about 5hp less than the new gen KTM 450), but is pretty much signing off around 8krpm, where the 4's are still developing power(depending on motor size) til 10-13krpm +/- 4's also get better traction cuz the less frequent power stroke digs into the ground where 2's tend to sit on top and wanna spin more, which obviously is less efficient when trying to drive forward.
Secondly-and more predominantly- this thing rides SO MUCH smoother OVER BUMPS(the polar opposite of what the dude said in this vid) than a 4-stroke. Heck..my '22 350 has cone valves on it, and this thing's air forks suck up the chop at Glen Helen(where coincidentally this video was shot) better. Everyone knows the last gen KTM 4-stroke chassis is so much more forgiving than the new gen 4 stroke, and for whatever reason this bike is more comfortable to ride, more forgiving, and 'fits'(I'm 6') better than even those bikes. The new KTM 4 stroke chassis feels like your riding on a steel girder with wheels, so we're talking night and fricken day there
Lastly, IMO/IME this thing corners better than large displacement 4-strokes as well. You can be stupid/lazy and enter a turn with your weight falling off the inside, and this thing will stick in the rut and pull you through. 450's wanna stand up in corner ruts cuz of their huge amount of crank inertia, and 2-strokes obviously have much less rotating mass
This is a really fun bike. It's light weight(btw I weighed mine and it came in at 220lbs on the nose with no fuel-'professional' calibrated scale), it rides even lighter cuz of its lighter rotating mass, it handles like its on rails, and the rider positioning is really comfortable
Great knowledge on the 300. I am in the market for a 2 stroke. I was looking at the YZ pretty intently. Now, seeing the KTM I have my reserves to the KTM. How much better is the 300 vs the 250 KTM?
@@crusader4273same here. I think KTM has been technologically advancing their 2 stroke bikes. While Yamaha has been more or less making the exact same thing for years and years. I have a soft spot for the Yamaha, but KTM has electric start, fuel injection, an actual fuel map that adjust based on elevation 😳 Yamaha has none of that. I’m just looking for a woods/play bike. But something I can wrench on easily if needed, and also something super reliable. While I’m thinking Yamaha is the go to. The KTM is certainly the more advanced machine. I’ve ridden street bikes my whole life, with little dirt bike experience outside of RM85’s etc when I was a kid. But it seems like KTM is the only machine that has advanced in 2024 and offers you something with some more features.
Go 2025 husky 300 TX
Best sounding stock exhaust ever made
So nice to see the old 2 bangers still in production 👌👍
Not only still in production. There thriving
New School Smokers 😎 Happy that i supported the movement by getting a 2023 TC125 🙏
This is the latest dev in 2-strokes since forever. Those old 500 engines havent even had an upgrade in 30 yrs. But imagine if they did with things like direct injection or EFI, vibration reduction, the latest frames, etc They would easily be competetive against 450's. Probably why AMA only allows 250 2-strokes in the 450 class.
Once you start riding that two stroke hit it’s hard to stop, you want every bike to hit like that at least I do 🐾✌️🇺🇸
You 2-smoke lovers better be buying these new models as well or they will be GONE for good. Facts.
I have a 23 SX 250 and love it - amazing machine
How many hours do you get on a set of rings ? Any top end failures ?
Just bought this 2 weeks ago love this thing
This has got to be the ultimate bike.
I would go for the 250 but yes
@@chalo212can I ask why the 250?
@@Alex-mv8br Plenty of power, even pros dont need more... Lighter, more agile, and you ride it a little more in the revs which sounds and feels cooler
Ron Lawson, straight up Top G! Gives such well put insights, and info. 🍻 Cheers on a great video.
@miles makes sense per my test ride prior to purchasing this bike. Mine has the Copperhead Racing tuned Ohlins Hybrid fork insert and Enzo shock treatment. Bike sticks like glue, but more nimble than a '22 FC350. Has a re-flash from that Florida tuner. Mapping is consistent, crisp and doesn't load up or go lean. A rut master for the rut challenged.
I have a 2023 300 tbi, it’s great in every way for me, except the random bog/cut out of power that seems to plague a handful. Did it on a jump face. A dudes new husky on a facebook group did it on a jump and he broke his shoulder. It’s like the kill switch is hit when you grab a handful of throttle. Some kind of electrical glitch, either fuel delivery or power valve, map reset…something. It’s very random and when you least expect it. Again, best bike I’ve ever had except this issue.
"easier to ride than an old ported and polished 250"...when I was racing in the early 70's and earned my AMA Expert License in 125cc Motocross my Dad the Rocket Engineer did my porting/tuning and custom built my downward swept expansion chambers...and my YZ125 had a very narrow RPM window of top end power, but man when it hit it was fun.
Got the 23 model soon as it hit the showroom floor, best bike I’ve ever ridden
My next quad build , will have this engine .
Xe đẹp quá bạn ơi
Is the Mild map torquey for trail riding and hill climbing ? Did you get 20 hours on this bike ? Keep hearing last years fuel injection eats top ends.
Wait until that map system goes nuts, be paying a fortune to fix it!!
I have 15hrs on my new TC250 but its '22. Right before it changed... I dont feel I'm missing out on much because im the type of rider that loves the mecanic part of MX. Its simple and still powerful and agile. But I do love the fact that 2 strokes will live on for a few more years. I'll eventually switch when they stop producing them hahahahahhaaha
Let go of the new bike addiction. I'm at no disadvantage on an old smoker with the right upgrades. I've got a 200SX('06 chassis, '17 YZ front end and STIC Super X carb). My '22 YZ250F doesn't throw shade at my PDS shocked 200 in any category. Bikes ain't gotten that much better. Says the new owner of this 300SX, as a back up. Joke, but it is replacing my '22 YZ250F. And yes it feels levels above my 200SX, but not as fun, to be sure. The 200 doesn't get yarded, unless the other rider is more skilled.
Thats a very interesting combination!! You ACED on that YZ250f, its for sure the best bike all around. Seriously there is nothing better hahhahahah@@ottokirk2325
GET is supposed to be offering a cdi soon for the new 2 strokes like next month
My 1992 Ktm 300 was tagged on the frame as a 300sx. Had a few things that were different from Exc models.
Dude that is awesome do you still have it?
I wish. @@STAY_AT_PLAY
@@billdeck9766I’ve let a few go too, life gets in the F’n way
@deborahchesser7375 that is understandable.. I'm selling my 2018 250sx and don't want to but I need a trailer to live in at this point. Haha
Ive got two YZ 250's.. are they worth selling for onna these??.. im thinkin a BRC 500 swap.. or try one of these..i love the two-stroke. Just want some more snap. Would this be worth it?? Cheers
How much power does it put down stock? And how much power is it capable of with some mods and upgrades?
Hello stock 57hp.
remapping and full exhaust fmf + head squishband.~62 but more torque
Does this have more power than a standard two fitty? How does it compare to the yz250?
The bike is a 300cc so it will have more power than a 250
I doubt it but wonder if they'd even sorta hang with a stock 450 I know the ama won't let them race but power wise I wonder how close they are to a 450 in power
I’ve got the 23 300 and I would say it’s about equal to a 450 except in the low end but even then it’s still super close
Dyno test?
I thought these had oil injection I thought that was cool but have had friends with sea doos that the pump burns up they didn't know and locked up the engine so I guess I'm fine with it but not having to mix gas is cool
So what’s the difference between the sx-f and sx besides one being a 2 stroke and the other a 4 stroke
I seen these bikes tear yzf450's, a raptor 660 and a rm250. And I'm partial to suzuki 2 strokes, and yamaha 4strokes. Granted the 450's and raptor were dated in comparison
Cmon boys help me pick! 2023 Ktm 150sx or a 2023 690smc r?
There's enough to do in a MX Race you don't need to be switching between 5 MAPS, 2 is enough KTM HAS LEFT NOTHING ON THE TABLE WITH THIS BIKE should be a good vets bike or a practice bike with 58HP
Ridden both 450 and 300 2 t. The 450 is a tractor and so much easier to ride. Yes the 300 light and quick but put that 450 in 3rd gear and let her eat. It pits the power down. Sorry 2t the 4t just an easier bike to lug around
“So easy a beginner can ride it”. Yeah no thanks
why would we want a 2 stroke this complex? can't do this, can't do that...everything locked down. And oh to change it you have to buy a new ECU for $1500 and additional sensors that will eventually break and create codes that you can't figure out, while you spend more $$$ going to a dealer because they are the only ones that can actually figure out whats wrong. This whole fuel injection for 2 strokes was a step in the wrong direction. My 22 SX250 has a Keihin carb and makes more power than my friends new TBI300. Is far more reliable, and won't leave me stranded in the woods.
Say what?..Kymco stamped on the cylinder?
That smells like crap alloy
No KTM need to go about it properly and build a 350 SX they would be so popular KTM would wouldn’t be able to to build enough of them
Or even a 400sx 2T
It looks like cylinder has been manufactured by Kymco and not Athena anymore like it has been for many years. Cylinder has text ”Kymco”. Strange...
They where made from Elko, not Athena, but yes, you are correct
@@MX-rd3fc Yes it was Elko and the pistons and gaskets are from Athena.
My 21 250sx has a kymco cylinder not elko nothing to worry about good quality stuff
Nobody even knows what the horsepower is. KTM told them not to tell anyone.
Life is stupid so im just gonna ride
Where can you ride these in California?
Tracks and Private Property only. 😞
@@cd155mx Why the hell would I buy one or even be interested in this video.
You can ride these anywhere in california. How do I know? I live here😂
dmv sent me a red sticker for mine. dealer told me people were "getting lucky" and were receiving red stickers and sure enough I did.
@@shannonwilhite3475 Lucky for you. It will be interesting to see what happens to the post 2021 folks that got red stickers once the program sunsets in 2025.
5 maps? No.
airfork sucks
That thing doesnt have any power
I think I’m trading my 250 sxf in for a 2 stroke because I don’t wanna adjust valves
Good idea, you’ll be replacing the top end, instead of the 4t valves. At the end of the day, they’re both great, & maintenance ends up being somewhat similar at the end of the day. Since you’ve already owned a 4t, definitely get a 2t next. You need to experience the best of both worlds. Go the 2 banger next, enjoy 👍.
Dump the air forks don't know why KTM keeps them junk in my opinion
Definitely NOT junk. Facts.
Trash!

Honest question whats is the last year bike you rode with air forks they've come a long way. Buttery kyb has a soft spot in my heart
Eh I have a '23 GasGas MC 250 2T and I don't think the forks are that bad. I set them to the stiffer "sport" setting and they're perfect.
