- Where does the all-new 2023 KTM 300 SX two-stroke slot in for horsepower and torque when compared to the 350 and 450 SX-F four-strokes?
Спорт
Glad someone made this video, especially between the 2 maps. Still love my 300 TBI though ;) Looking forward to the track comparison!
I bought a ktm 250 sx in the spring and I just picked up my 300 sx efi.. I got to ride it for about 45 min and now we have snow :( So far I love it but I'm looking forward to riding both back to back.
It definitely pulls harder than the 250 but still very easy to ride. Can't wait to get more time on it.
I'm actually thinking of making a you tube video to compare both bikes..
I'm thinking some people would want to see that comparison.
Yes! Let's see the vid
Wise choices! Great bikes. 👍🏻
I just got my 450 and I'm ready to trade in on that 300 😂
As always great work Michael! Looking forward to the lap time analysis (both fastest laps and average laps) - will be fun to see how the 300 stacks up against the 350/450SXF's. Also this all new chassis feels very different (in a good way) with a 300 2-stroke mounted inside vs the 350/450SXF engines - have the riders give some feedback on the chassis feel between the 2-stroke/4-strokes. Looking forward to the video!
Can’t wait to see the follow up vid. Thanks guys.
Thank you for making this video.
It's so odd to hear someone so smart with dirt bike (Race Tech) "it's surprising to see the two stroke being better in the torque curve and power curve." When there's not a stupid handicap, cc for cc the two stroke will out perform the four stroke every time.
Love short to the point videos.
KTM finally has to bring back a 500 or 450 two stroke. Imagine that curve but with 150cc more
🤤🤤🤤😛😛500 2 Stroke. Check out 999lazer on YT YZ500 conversion. Awesome.
@@carltonholmes8061 i saw it. But it's still a conversion kit for 10k
I got the husqvarna tx 300. I want the 500 kit. You can always use more power.
There was 100% something wrong with that 300SX, and I thought so immediately after seeing those numbers. Dirtbikemag has the 450 and 300 within 5hp of each other (54,59)there’s no way in hell it made less horsepower than the 350. Also the torque numbers are all over the place.
Agreed! I rode a 24 300sx today and let me tell you it pulls like a 450 it’s absolutely insane. We also had a 350 EXC and it felt way tamer on the top end
@@breckboy654 that's because the EXC is detuned 350 that only comes with 37 horsepower.
Keen to hear your thoughts in comparison test im currently debating whether to get a 350sxf or 300 sx
17% more power than the YZ250, and that curve is textbook. Awesome!
Love to see those Dino charts. I couldn’t really read them though they were kind of fuzzy and on the screen. It would be cool if you could post those charts at the end of the video in high def.
I suspect you need to check the res on your side, or else go do a eye test. Thank me later :)
Fact is KTM makes many excellent models. These are good times for MX enthusiasts. KTM 300SX should be *ultimate* bike for 2-stroke guys!
Great Video, thanks. What's this like as a Vets bike?
The 300's are wonderful bikes, I absolutely love mine.
I bought the 300sx a few weeks ago. Was debating this or the 350. I'm glad I got the 300. It costs less, maintenance is simpler and it's a bit lighter. And it's more fun to ride! I do think the 350 powerband is better. That bike holds power longer like my old 250sxf did.
You can make that 300 faster than a 450 sxf. Just modify it.
Plus it will sound better than 4 stroke
@robd1859 No, not really. Even if it can match the power and torque of a 450 the 450 holds onto it's power for thousands of rpm longer than the 2 stroke can, which means I'm already shifting into the next gear and losing torque at the wheel.
Both are excellent bikes! You made a good choice. I'm more a 4-stroke guy as vet rider now. Can't beat power delivery of modern 450. Do like KTM 250/300SX tho. -Ohio
I assume it shows different due to crank vs wheel hp, sweet bike I just picked one up :)
Lemme know how it feels on the track.. I have a '20 yz450.. thinking about jumping to a 2 stroke but don't want to have to shift...ever.....ever again lol
What was the top speed seen on the dyno for the 300sx?
These bikes have a hidden map. You guys should test it
id like to see the husqvarna 250 2t vs ktm 250 2t vs ktm 300 2t. dyno comparison
Candidate for the best snow bike? Light reliable and horsepower..
motocross action dynod the 300 tbi a few months back at 55 hp vs 59 with the same year ktm 450. Hm.
Can't see the numbers on my phone.
I’m buying one of these can’t wait to ride it
I want one so bad
Thanks for this information. I was about to get me a 350 now I’m changing my mind. 😄
I’m not sure it would be as good as you would expect. The heavier the rotating assembly the less advantage you seem to get with 2 cycles. I would expect seeing 500s dyno against 450s, the results would be closer than you think.
Most people are only going to use 75% of the HP of any of these bikes.
What fuel was used in this test?
91 octance pump.
Where did the300 vs 350 vs 450 video go???
Look for it early next week!
Little clickbaity. It makes more than a 350 at the 300’s peak output. The 350’s peak output is more.
Who cares, it makes plenty of power and sounds and smells great!😜
Only after the 4T revs out to 8 million rpm, by that time the 2T had spooled up and is already in the next gear. BRAAAP
Besides, the *buzz-bomb* has *NOW!* power.
@@dennisyoung4631 Ya, Mon✌️😎🇯🇲🇺🇲 BRAAAP
@@vetb882 kinda like every other 2 stroke when it tries to keep up with a 4 stroke
My 2008 ktm sx 250 has a map switch (ignition switch basically) so i don't see why you are surprised by the map switch.
Non the less the ktm sx 300 looks like the perfect do it all bike !!!
Yeah you pretty much answered the question yourself, you have an ignition timing map which does fk all. Where this has an ECU map switch making a large 2.5hp difference and opening up an aftermarket for tuning, like with a vortex
@@Runk3lsmcdougal ignition tuning it's a thing you know. And since the sx300 2023 has an ECU there was no way they wouldn't put a map switch, it's KTM.
I could care less about the 350 but seeing what that 300 makes compared to a 450. Ouch lol I guess there is no replacement for displacement. Assuming this is the same dyno. I could care less what the peak number is as long as it’s taken on the same dyno.
My 2020 FX350 pulls 52bhp and 30 lbs, I also have a 2023 Fc350 which feels more powerful, my 2020 FS 450 pulls 56bhp on the Dyno… all I can see is the 300 pulls 44bhp?
350 made about 47.8 on this dyno, but another 3,000 or so RPM up the range from the 300.
Can't compare across different dynos.
@@OtisFlint you need to watch the video again.
@@iainhutchinson345 You're quoting numbers from a different dyno, I'm not the one misunderstanding this situation
Different dynos
Cool video
Freshly released 300 dyno chart from dirtbikemag show 5 horsepower deficit versus 450 and then 2 ponies less than 350🤓
All this tells me is the YZ is still relevant even without electric start and any updates plus it’s way cheaper
In what way is it relevant after seeing what this beast can do?
The KTM is much lighter and has a stiffer frame, better suspension, and more power everywhere. Basically a clapped-out YZ250 ready to race. It's worth the money.
If KTM could go one step further and make a gas gas 500 2 stroke they would sell in a bucket load people miss the open class bikes
What type of dyno is this? Reads very low numbers.
All the other places are giving bogus numbers. There's no 450 that's breaking 52rwhp in stock trim.
@@keithpeterson6108 - how do you know? Obviously you are entitled to your opinion. Different brands of dynos measure differently. Check MXA's 2022 450cc shootout. Four of the bikes made slightly over 58hp.
They said it reads lower than a dyno jet but they were looking at the curves.
@@stevemarquez9628 - thanks.
@Jaime
Because MXA plays games with their dyno numbers. They use a conversion to go from rwhp to crank HP & they also use a bogus correction factor. It's a myth that dynos read differently unless they aren't calibrated properly (junk) or when the operator makes bogus correction factor numbers. MXA has 500's measured at the rear wheel & then gives 4t's bogus "corrected" numbers & use converted crank numbers.
I own a dyno & have a number of friends who have them as well. Lots of BS out there.
...& I don't have an opinion. I have a dyno. It doesn't care about opinions pr feelings. It just says it like it is
350 four strokes should not even be in the equation because that's not the flagship of k t m. The 450 s x f is their flagship.
The question is how to make the 300sxas fast or faster than 450 sxf
6.5hp more than a yz250! What would a 250sx do? Thats worth the orange bike premium price IMHO
High comp head on a yz and some tuning would make up that horsepower
@@jonathoncatterson8901 not on the same dyno I wouldn’t think. Tends to be 3-4hp in a pipe, fuel and 2 degrees timing on a yz250. 6.5hp stock is a game changer
@@jonathoncatterson8901 Not even close, maybe 2 to 3 HP max with those items.
2 sTrOke hAs TwIcE aS mUcH pOwER cc FoR cc hahaha😂 only 50cc more and still more power
for the People using real measurements it’s 99,7Kg
The comparison is what matters at the end but when you post numbers you have to be a little near the reality… 300 2t 44 hp ??? what dyno is that ??? they are differences between dynos but the power is one. Calibrate your dynos or don’t post numbers at all… and the 350 from 2014 till now every year loses hp…
The majority of test we see in moto are on dynojets, which are known to ready quite high and close to the power output of the engine before drivetrain loss. The Race Tech dyno is an eddie current style, it reads lower and closer to the engine with the drivetrain loss.
I have to agree with the horsepower comment. My 2017 350 xcf definitely feels stronger than the 23 versions I have ridden back to back. KTM rated the 2017 as having 58 horsepower from the factory which I think is exaggerated number but it sure feels like it sometimes.
A good dyno is better than a 1000words.
So no numbers , click bate.
Numbers are in the video.
No way a yz250 is making 37 hp
Seems right. Keep in mind not every dyno is the same, and in fact they almost always read some what different. For a comparison MXA says the ktm350 makes like 54HP while this dyno showed it topping out around 50hp. It just shows the difference between dynos. This one may just happen to run a little low, but I know many of the shops around me also usually come up with lower numbers then what some of the magazines come up with.
Dyno reads about 5-6HP down on all the bikes. What matters is the runs at the same time, same dyno, same condition.
I just think all these magazines and manufacturers lie about hp. I've seen so many different hp numbers for yz250 I don't even know what to believe anymore
Should be 45hp
@@Fvission - so true! This dyno reads very low, pessimistic numbers. YZ250 two strokes and KTM 250 SX have been measured at 46 and 48hp respectively on Pro Circuit's dyno. There are three types of dyno configurations - inertial. A/C and Eddie current. Measurements are different.
It's a damn expensive dirt bike and I believe the end is coming to two stroke engines due to stricter emissions regulations. "To equal the hydrocarbon emissions of about a half-hour of yard work with this two-stroke leaf blower, you'd have to drive a Raptor for 3,887 miles, or the distance from Northern Texas to Anchorage, Alaska.”
You sound like a califailian
That is absolutely not true!
In fact it’s a complete lie!!
Is this title a joke???
2 strokes always made more power for a similar displacement to 4 strokes. Talk about a clickbait title 🙄😒
Funny part is it actually doesn't
It does at the same RPM but the 350 makes more peak HP as it keeps revving.
Dyno numbers “on the same dyno” say different
Yeah but the 350 has a smoother torque curve and thats always the winner!
👎 Two Strokes baby 🤘. More Power to KTM for making a competitive 2 Stroke
350 for the win
Four strokes are for frogs. BRAAAP!
And yet, the 2024 350sx is making 50whp, and the 450 is making 54whp..
the last thing I want from my 2 stroke is to be like a 4 stroke. i don't understand this type of thinking.
people say the cost of 4 strokes ruined MX
people say the power of strokes ruined MX
people say the weight of 4 strokes ruined MX
if 4 strokes have "ruined" this sport (especially SX), it's for one reason only. Traction.
I've been say this for 20 years: more traction = less fun
2 stroke = least traction = most fun
4 stroke = more traction = less fun
electric = most traction = least fun
this is the difference. this is why racing isn't as exited and this is the reason electric is going to be even less exiting.... for no other reason..
the whole entire essence of "off-road" racing is that it takes place on loose, less predictable terrain, as opposed to road racing and it's consistant traction.
Professionals will always want what is most predictable and so do most customers. If you think racing is ruined and think traction is lame...might just be a personal problem..btw i ride and race 2 strokes but its not because of the traction. I think you are a bit confused.
You are exactly 110% right. I want my 2-stroke MX bikes to run and ride the Opposite of a 4-stroke. I want snappy, explosive power, hard hitting on/off powerband. An a 2-stroke that I’ve gotta work the clutch hard to keep on the pipe. If I wanted smooth, liner, controllable, torque’ power I’d buy a 4-stroke !
From a lifetime 2-stroke specialist-There is so much more to be gained from a a 2S that can get the power to the ground in a predictable way. You may think it is not 2-stroke enough but you forget all the other great aspects of feel and lightness and flickability. A snappy but not light switch power will only improve all of these already superior features. 4S are boring to me but I’m pretty sure my new 300 won’t be when i get it. Think about the whole package.
You obviously haven't ridden the Alta MXR, as in map 4 you get 50 horsepower all at once if you want it, and it's just pure tire spin everywhere. Drift city. So much power, more than the 300 2 stroke, lol
