Two stroke versus four stroke is the oldest argument in dirt biking. 2 stroke riders would have you believe that 2Ts are much lighter, and much faster… however 4 strokes tend to be quicker around a circuit. So what gives? Well, I wondered if after 15 years of 4Ts being the favoured engine type for motocross racing, their rigorous development had caught them up with what undoubtably used to be the cream of dirt bike the crop. So myself and my mate Kynan, set up a drag strip on the Lake Station farm in New Zealand (no idea how long it was btw) and raced his 2020 Husqvarna TE250i (2 stroke) against my 2021 Yamaha WR250F (4 stroke) four times, then we swapped over and did it again on each other’s bikes to hopefully try and settle for once and for all, what’s faster… 2 stroke or 4 stroke?

Which do you guys prefer, 2 stroke or 4 stroke? Also, would anyone like to see more of this? Maybe next time we could do a handling test 🏁

They both have a place. For every day riding I’d prefer a four stroke. Slow technical stuff two stroke, fast trails I can keep a lot of momentum? Two stroke. Motocross track? Both
4 stroke Benefits : Better Traction at speed. Can sustain being reved high. Generally have a higher top speed, Power on Tap at low revs. Engine braking, Better fuel economy ... Hence why they are used in Motocross, Supercross. 2 Stroke benefits: Much more Torque, much quicker acceleration in the Mid to High revs, much lighter feel, more power per CC, cheaper and easier maintainance ... Hence why 2 strokes have dominated the Hard Enduro Scene and still make regular appearances at Enduro GP events depending on the location and course layout. Overall there is no real 2t vs 4t debate. Its literally different strokes for different folks. Go with what makes you happy and what you prefer for the type of riding you do.
Good comparison exept one thing: I always hear that maintainance argument but it confuses me a lot. Of course if something happens it'll be much more expensive on the four stroke but in my experience 4 Strokes generally last forever without any maintenance. My Dual Sport Bike is 25 years old and has around 24855 Miles on it. Nothing has ever happened to the engine and except for an Oil change every 6k Miles no Maintanance was required. If it was a 2 Stroke it would have probably required a new Piston / Top End Rebuild by now also much more Oil changes.
Forgot to mention the sound for 2 strokes
@@michaelnutzel2226 a full on competition enduro or MX four stroke would need a lot more maintenance than that. Mine needed a new piston at 185 hours and the valves needed adjustment at 140. 2 strokes generally need maintenance slightly more often but are easier and cheaper to sort when they do. Easier to diagnose a two stroke problem too, generally speaking.
@@Mockle07 I know competition Bikes need more maintenance and that 2 strokes are easier to repair. But in my experience 2 strokes just need so much more that I'm wondering if it's actually cheaper.
@@michaelnutzel2226 I agree, I think ultimately over time it’s much the same. I think it depends on whether you do your own maintenance or not; the average bone head level mechanic (me) would be able to do the vast majority of 2t engine maintenance but would take a 4t to a shop for most engine work. Ultimately though I think you’re right, 4t engines are way more reliable and easier to work on than the old grenade days. I race (badly) and know very few people who have any major issues with recent 4t engines.
I’m old school. I totally dig 2-strokes over 4’s. I wouldn’t mind a 4-stroker for a dual sport or a street bike but that’s about it for me.
2stroke just so much work
@@waydeyoung2748 if you take care of them they last a long time just like anything else.
@@waydeyoung2748 3 moving part’s. I think not
@@waydeyoung2748 mixing gas and replacing a piston each season? Go buy a 4 stroke and letme know how much work bud.
Yeah 4 stroke for the street/dual sport. 2 stroke for enduro.
Enjoy the video once again. Although. A 250 2t puts out far more power per CC than a 4 stroke. Its anywhere from 30 to 50% nore depending on the era of bikes. Remember that 250 2t competed against the 450 4t before 4t motors took over most racing.
I think its 250 2t vs 350 4t demanding on power
The real facts is that, a 250 2 stroke should race against a 400cc 4 stroke. Thats the closest to the real deal you can get. But now when i think about it. A Honda Cr500r has 56,25 rear wheel horsepower. 2021 Honda crf450r has 55 rear wheel horsepower.. And there you have it, Facts.

Your channel is super underrated, I believe it will grow substantially this year!
🤞
Love the way you guys interact with each other, not bashing just having good fun
Love the new channel icon pick man👌 jus as good as the content
Personally I’d take the 2 stroke over the 4 stroke with the same CC. But with how good the 4 strokes have gotten but the biggest issue is flame outs at low speeds dam annoying. I do hope KTM comes out with a 350cc 2 stroke and be allowed to compete with 450 4 strokes competition wise.
I’ve got a WR250R and it’s never flamed out. My buddy has aCRF450 and it hasn’t flamed out. For whatever that’s worth.
@@krispewkrem3 Try getting off the fire roads bud
On equal displacement the 2-stroke is going to have a significant advantage, not 2X but more like 25%.
Never understood the division between the two. I love both engines for different reasons and at the end of the day its just fun to go riding. That being said I never raced or competed in enduro events it was all the the fun. But what I can say is I will never forget going from a 125kx to a 250kx for the first time, my friend was about 100lbs heavier than me and made it look easy to rip. I nearly ended up in thorn bushes.
This video was interesting for the first couple of minutes. But I was much more interested to see which one would perform best up in the hills and trails over yonder. I'll be waiting for you ;-)
i ride supermoto and since i only have the license for 125s i prefer the two stroke because you can get close to 40hp and with 4 strokes like 12-16hp so theres a quite big difference
Are u comparing a 125 2 stroke with a 125 4 stroke?
@@bruhroyale12123 yes because both can be ridden with a a1 licence
@@mfnspirdoo Wel that’s a bad comparison, we all know 2 strokes produce more power per cc but we go with 125 two stroke with 250 4 stroke and 250 2atroke with 450 4 stroke. No one compares it like you for obvious reasons
@@bruhroyale12123 quite a lot of people in the eu do for quite obv reasons: you can ride them on street at 16yrs old
@@mfnspirdoo really? Isn’t there a power to weight ratio restriction aswell? Not just the cc’s?
Way back when I was 15 I bought a Kawasaki 175 enduro 2-stroke with oil injection (early 70's model). As for 2 vs 4 stroke, just look at the old Yamaha RD400 and the Kawasaki 2-stroke triples. No 4-stroke with the same displacement could even come close.
I remember when Yamaha released the 426 and they we're still racing two strokes. They allowed them to race in the 250 because they were about on par power wise and with the 125 class it was the 250 four stroke up until they got rid of two racing all together. When you race the same cc in a two stroke vs four stroke overall the two stroke will win.
The husky seems to be catching the yammi even with slower starts. I'm impressed that the 4 stroke is so evenly matched to be honest because the 125 two stroke was really what the 250 4 stroke would have be matched against in the early years. Still gotta go with the two stroke but it's probably more my age and I have a soft spot for them because that was the thing when I was a teenager.
Anybody who knows bikes knew what was gonna happen, but that was still really entertaining. Cheers!
Everyone knows their both great bikes and it depends on what kind of riding your gonna do. But now that you don’t have to mix fuels anymore in 2 strokes I’d take a 2 stroker myself. But that’s why we have choices…👍🏼👍🏼👍🏼
I have a yz490 and an ossa 250 trials bike………love them both, had them since the early 80’s……….well maintained and still ride them both
I had a CR 250 and that was the fastest bike I've ever rode. I bought it brand new. 2 stroke is faster than the 4 stroke all day long
I've got a question ⁉️ um, I've Google it couple times but still unsure um, how much hp did u add to your wr when u did mods, I even tried looking for that video on your page
Both insanely fast loved the video
Great video. I bet if you uncorked the WR the results would have been different. Did the wr have the throttle stop screw in it?
goes to show either can be tuned to do what the other is "supposed" to be good at. good video
I’ve got a question, I wanna know why the headlight on the WR was off was it off or does it have the same headlight issue as most WRs like mine
Great vid fellas!
thanks so much for this comparison...... 😀👌👌
Really appreciate the time money and effort put into these videos cuz ! Definitely prefer the shorter action packed style of filming !
Spent many hours and years on a Husky 250 CR, lots of mountains and mud and everything in between, including slow crawl trials-type stuff over dead falls etc. through tangled forests with no trails. Loved it! Steep mountains were fun and tough, and when you’re young it’s all good. In my mid 50’s rode a Christini 450 4s with 2 wheel drive and a recluse clutch. Steep climbs that I’d have to think long and hard about if on my Husky were a breeze with that Christini, just point it up hill and go. The extra torque at low rpms from the 450 combined with the front wheel pulling as well, I could play around all I wanted, not having to worry about the power curve on the 2s, or keeping the front wheel down by laying on the handle bars while trying to keep the rear from spinning by out finessing the throttle. Need to stop for some reason? That recluse clutch let the engine keep running. No trying to start the bike while holding the brake and giving it gas at the same time, all while fighting gravity and slippery slopes. Although I didn’t get to try it in the deep mud, I bet it would’ve been just as impressive. Granted, it could be argued that the Christini took all of the fun out of riding, but at my age it allowed me to go places and do things that I would’ve been hard pressed to do otherwise.
Even in the outboard motor world, 2strokes are far torquier and stronger than 4strokes. However, few manufacturers are making them anymore and 4 strokers are more fuel efficient.
Absolutely mint.
What do you use to mount gopro on helmet?
Loved the sweet smell of Bel-Ray in the morning. Used to get behind the person using it just to enjoy the smell. Not sure if it's still around. Haven't used it since my racing days in the the 70s-80s.
I'm thinking same thing want a new bike just not sure what maybe a yz250 maybe a wr yzfx 🤷 so watching these vids and outcomes and opinions is good 👌
get a yz250 2t, i have one and its by far the best bike I've owned, works equally well on tracks and out on trails, absolute perfection in a proper off-road bike. dont go 450 theyre just ridiculous lol noone needs that much power
Hi Ash should I get a 4 stroke or a 2 for my dirt bike just want to kwon
Well, defintley the 2stroke is faster when compared to 4stroke engine that has a similar displacement. I would prefer a 2stroke offroad motorcycle because you do not feel the engine moving parts inertia in corners on the motocross track or in the rough technical enduro sections.
@@noidontthinksolol its not bs its very simple lol, a 250f is never ever keeping up with a 250 2t, a 250 2t is in the racing class open with 450s where as a 250f is with 125 2t in the lites class
@@noidontthinksolol hahahahah you have no idea
@@noidontthinksolol a disadvantage of four strokes is compression stalling. If you stall the engine with the back brake, a 2 stroke will almost always restart when you let off the brake, as long as you're still moving. A four stroke will stay stalled.
Awesome video Ash
I’ve got the 2023 fully unrestricted with the competition ECU and the CCU with the handlebar switch this new wr is a beast so forgiving in mistakes I’ve learned Turing the idle up a bit and keeping the rpm’s a little higher helps with the stalling and clutch lots of clutch in the technical shit
Love your vids
How long was the length from start to finish?
I had a '20 Husky TE 250i for a while and rode my buddy's '21 YZ 250FX back-to-back with mine and the 250FX felt pretty gutless in comparison if I'm honest.
I ask this with my Father "which is better 2 stroke vs 4 stroke?" he said to "We don't compare something that is different but something similar. 2 stroke and 4 stroke are two different engines both in performance and characteristics we compare to find difference not highlight them" then began to nag me about my life hahahaha.
I was raised on a 2 stroke and little has changed for me! However they do make some nice 4 strokes now.
The WR is a tuned down 250 4 stroke. The Husky it putting out over double the HP and 30% more torque. Even compared to the super hot YZ250f, any 2 stroke 250 will destroy it, from any brand.
It didn't.
On a four wheeler, I have ran a 250 2t against 400 4t and did well against them. When they went to 250 2t against 450 4t, I could run with them. If they had the 4t built, they had more power.
Great video… !
Idk where the question is tho! The husky looked faster every time. The wr took it off the start, than the husky blew past, if you where on pavement the wr would than again pull past in the end
You think? i dont think because at the end is when the 2 stroke is in his powerband and makes more hp than the wr. The WR has more of an bottom end advantage
@@yannhayon2796 the husky maxes out at around 8600rpm or less where as the Yamaha revs to Close to 14k rpm. Nearly double. The husky is maxed out and having to slow down while the Yamaha is just getting warmed up. Both fairly equal playing fields, they just both excel in different places. The Yamaha doesn’t have the bottom end torque that the husky has. The husky makes more hp but it’s narrow and short lived where as Yamaha makes significantly less hp. Around 8-10hp less but the thing Revs to the moon and makes power the whole time. These modern four stroke 250s ride much more like an old 2 stroke than a modern counterbalanced two stroke does. His yz250 “Ktm killer” would blow both of these bikes out of the water in a drag race. But it would only win in a drag race or real motocross style race. On the road, Supermoto, harescramble, enduro the ktms besting it and so is the wr
If you ever owned and rode both 250s its not even close. 2t will spank it all day every day
@@superwilcox9026 I’ve owned and currently own both. I own a 2017 crf450r 2021 kx250 and 1998 kx250. The modern 250fs rev well beyond that of most or really any two stroke does and makes power almost to the very top of that. They ride very similar to older two strokes. Just smoother and more predictable. You have to rev the piss out of them and stay in the upper rpms to get any power out of them which is the same as a 2 stroke
Drag race the old yz250 against that wr and see what happens lol it’ll blow its doors off
It would beat it by a little bit but a mint yz250 would smoke it
They aren’t comparing motocross bikes
Depends on gearing I have a 5 valve wr 2004 with the typical tricks and pipe rejetted carb. Took away some of the hit or wheel spin put 1 tooth larger countershaft sproket bike is absolutely a blast hauls ass ride in Dez in so cal. Bike did 93 on Gps. By comparison my wr 500 2t with 16 44 gearing topped out at 108. It only spins 6800.
There's no comparison! A 2 stroke fires twice as much as a 4 stroke so obviously the 2 stroke will always have more power! (naturally aspirated of course)
Correct to an extent. Compare a 250/300 2 stroke with a 450 4 stroke and the results will be similar. Comparing a 250 2 stroke with with 250 4 stroke is not even a competition. 2 stokes put out more power per CC
@@braidenhills2417 they will not be similar a 450 puts out near 60 hp the 250 2t puts out low 40s
@@vaughanhodgson the 300 will put out about 3hp less than the 450. Even the best riders in the world can't put that much power down on the track lap after lap.
I’m trying to buy a Suzuki 06 rm250 I thought was a 2 stroke but he said it’s a 4 stroke any information is much appreciated
When changing the muffler on the WR250F to an after market muffler, the engine will feel much stronger. the stock one is pretty much restricted. On dirt rider KZhead channel, dyno test of stock WR250F and stock YZ250FX is about 3HP difference, both bikes are basically the same engine with different mapping , muffler and flywheel.
Depends on where you live. The UK WR is fully uncorked from the showroom, in the USA for example, it is not.

good vid mate
If you are a good enough rider the 250 two stroke will smoke the four stroke 250. The reason such a topic even comes up is that there are very few riders that are good enough to make the superior two stroke work. So if you're a novice or intermediate, a 250 four stroke or 125 two stroke is the way to go. If you're an expert rider you can make a 250 two stroke work wonders for you. As for 450 four strokes, have you seen what Ryan Hughes has said about them?
Scenery is beautiful. Where was this filmed?
Im a better technical rider on these newer 2strokes, but faster on the 4 strokes and generally get better results racing cause I do less shifting and they seem a little more Stabil as the speeds go up. although a little heavier, they wear me out less. On knarly terrain, ktm/husky 2t get awesome traction at really low rpm where as 4t typically wont even stay running with much less than idle rpm.
I have a 2021 te250i and my buddy has a 99 yz400f. We had a drag race on pavement(private road) and the 400 was leading by 1 to 3 bikes until around 82mph then the husky walked around.
Four stroke is like a race car that lost two wheels. Two stroke is like climbing on a bottle rocket and lighting the fuse.
I did run a hare scramble a great rider had a Trials tire in back on a 300 KTM XCW . I asked his friend why and " He said don't question him he's taking this race " . He did . I ran a trials tire on the rear of a 74 Rickman 125 Zundapp six day and loved it. Still have the Rickman . My father in law always tractor pulled with worn tires and that worked great. Tires matter. 😎
How much you want for the wr
Twenty pounds more of rider weight makes a huge difference. It is interesting that the 4 stroke did as well as it did, but the engine probably costed twice the money to manufacture, as the 2 stroke, if not more than that. There were too many variables, drag racing on a grassy, rough, slightly wet surface, like this. Tires the same on both bikes and dragging on a paved surface, would be much more telling, and accurate. I prefer a 4 stroke for traveling or joy riding with a lady friend on the buddy seat. I prefer a 2 stroke for playing around in the dirt, or woods. Keep the residual exhaust out of the combustion chamber on the power stroke, and back pressure out of the intake stroke, of a 2 stroke engine, and it would be back to the drawing board to get a 4 stroke to keep up with it. It would be difficult to beat a power stroke on every crank shaft revolution.
Well from a riding stand point being a younger guy i absolutely loveee the 2t 250 its lighter very easy to wip around amazing for trails and there very easy to do maintenance on and a lot cheaper 4t 250 its fun it just doesnt have all theeat and potatoes that most want out of a bike its too smooth to be honest its fun but after a whilr the 4t just gets boring both fun bikes and you definitely have to have more respect with a 2t cause you actually have to ride the bike u cant just twist the throttle and put around like you can on a 4t
With 4-Stroke closing in on 2-Stroke performance, I think 4-Stroke is the future, just because of emission compliance. 4-Cycle engines burn cleaner, and are more lending to catalytic converters and oxygen sensors, which makes them cleaner and more fuel efficient. On a different subject, most outboard boat engines used to be 2-Stroke, but now, they've given way to 4-Stroke for the same reasons. Both motorcycles and outboard boat engines are considered "high performance", because of their high horsepower to weight ratio. 4-Stroke engines are also much more forgiving to prolonged engine braking down hills, because they have oil in the crank case. With 2-Stroke, letting off the throttle also cuts off oil supply, which can cause damage if done for prolonged periods of time. That's why virtually every street bike is 4-Stroke. (besides emissions)
It's pretty easy to oil them. I've been waiting for sled tech to catch on. My rmk has an oil pump that lubes the bottom bearing directly without injecting oil into the intake. A properly running 2t should be maintaining an oil bath in the bottom end, which is only lost when you go upside down or drain the case. Big reason they want a super high oil to fuel ratio on a fresh rebuild.
I have no idea why you guys choose the surface you did here, its slick as hell and requires too much fineness to hook up. I would like to see them both race on a hard dirt surface and I can almost guarantee the 4 stroker will get smoked every time. Also they need to have identical tires, gearing is subject to personal preference but does play a huge roll in the outcome.
This is the real world. Not every test needs to benefit the side you like.

This was like an episode of Flight of the Conchords. Ridiculous, but worth it.
Too bad in my country, motorcycle manufacturers stopped making two strokes because of the air pollution it makes 🥲

2 strokes are fun to race (power) 4 strokes are fun for trails (comfortable) my 2 stroke race bike has short gears, so its great on tracks but now i want a 4 stroke to ride trails, because the gearing on my yz has a low top speed with too much shifting
Exactly, my wr is perfect for light hearted trail rides
Tested and proven even in dragrace in underbone same CC 2stroke always win
a good video however i would say that this is an unfair test as 2 strokes produce much more power compared to a 4 stroke of equal displacement.
How is it unfair? This is a comparison between 2 and 4 stroke.
@@gorybonghit3211 yes but its comparing a 250cc 2 stroke to a 250cc 4 stroke. normally i believe its 150cc 2 stroke too 250cc 4 storke as a 2 stroke gets more power per cc
These two bikes are the ones I’m trying to get this year don’t know which one I want
Next time try a sandy uphill, the 2-stroke will shine because of 30% more torque.
Do a Husky tc250 vs a yz250f
The gulf between two and four stroke off-road bikes has narrowed considerably since the 1970s when 2t meant narrow power and lightness and 4t meant heavy and big capacity. Now weight differences are marginal and power has really blossomed for small 4ts. All I can say is that for those tarmac stretches 4ts are happier with constant throttle than 2ts and 2ts just have that response. But if you like engine braking 4t is king. Spoilt for choice then?
Damn that 2 stroke is quick!!!!

13:16 I picked up my brand new 2021 WR250F 7 weeks ago, my highest top speed is 145km/h on a dirt road on a very very slight down hill and then back up that hill again 143km/h. Obviously this is recorded on grass and probably a shorter distance than I hit on mine but yeah 🤙
Interesting, I took mine down the actual road after this (not going to post any footage bc I don't want to go to jail) and got it up to 158! Flat road, but I was tucked right down and there was a slight tailwind. The bike sounded like it was 100 revs from the rev limiter at that speed so I would guess you could only ever get to 160... Still bloody impressive for a 250 enduro bike though imo
@@ashsowman wow definitely! Insane amount over power in them. Raced my cousin on his 16 Yz250f fully kitted race bike (Akrapovic full system etc) on the race map on the wr and notice it was pretty much necker neck then when I put it back into the stock map I was pulling away!
Every time I race my 2003 yz85 against my friends crf100 Klx140 and honda 250 sport quad I always come out on top
I only drove 2 stroke 50cc in the 1980's. But I'm not a grease monkey, I only drove them, did take 'm apart to clean and put back together with help from dad (else I'd have a hand full of nuts, not knowing which I had missed) One of the bikes, Yamaha FS1, had a weird thing about it, normal top speed was about 65 KPH, driving for long enough to warm up, close the throttle, immediately pull full open, I'd hear and feel a 'KNOCK' and suddenly that same bike did over 100 KPH. I never figured out what that was or why it happened. I know the frame wasn't built for those kind of speeds, but at 16 years old, you don't give such things a second thought, the faster the better, right ...
I'm a kart racer... it'll always be two stroke for me... not to mention the smell of R30 :)
We need ktm killer ep 4!!!
2 Strokes are definitely better and faster to me.
Well, there's no 2 stroke on the market now that's going to beat a 450F. I definitely enjoy riding 2 strokes more though, because that's what I'm used to.

Raced my yz@50 h 2 stroke 81 model against 450 plus 4 strokes2012 models at nudge race track in Brisbane in 2012 left for dead off line finished 4th of 20 bikes after 4 laps
My two favorite dirt-bikes in the whole entire 🌏world🌎... lol Seriously, I ride a Husky TE250 because 90% of what I ride is hilly, tight, rocky terrain with plenty of water, mud and obstacles.... A modern 2 stroke engine is just better suited for this stuff. But believe me, I gave serious consideration to a WR250F... if the terrain I have was a little more open and faster I'd probably be on a WR.
Unfortunately 2 strokes are all classics in the UK nowadays. I've had a 50cc 2 stroke scooter from 16-18yrs then a DT125R. Then passed my test years later and had got a 1200 Bandit, a husky 701 sumo and a CBR600F4 and I love them all. Really would love a larger cc 2 stroke like the one in this vid though, with the balancing shaft for less vibes, that could be streetable too 👌
Nice views!!
I grew up with a CR250 , and RM250 when mono shock first came on to scene. Two strokes were the best.
This was not a balanced duel, 250 2t is stronger but the video was interesting and well shot and both bikes have their charms.
With a two stroke, every stroke is a power stroke. That is why Detroit Diesel was so prominent in genset applications, the recovery time for heavy loads was very good with a two cycle engine.
Love to see WR250f vs KTM350excf etc
Seems like if you changed out the drive sprocket and went one tooth less on the 4 stroke then it would be more competitive here.. But then again if u went one tooth more on the 2 stroke then so much for that advantage I guess
Which one sounds better....old school or new school?
2- stroke for life! 4- strokes are great, until you have to pay the price of a rebuild!!
What happened to the KTM killer
High quality video but a 250 2 stroke should kill a 250 4 stroke. You're comparing 2 completely different bikes as well. I'm a 2 stroke guy but I've had a KXF 250 and I have a 400 EX quad. The KXF 250 (yes it was the 1st year Kawasaki made it so it had some bugs) broke down so much I went right back to 2 strokes. The 400 EX is basically an XR 400 engine so it's bullet proof and not as high performance as a mx bike. I actually have a lot of respect for the Yamaha WR 250 and would like to own one some day soon. Let's say you compared a YZF 250 and YZ 250 the YZ would kill it the drag race.
see what bike is faster(and cheaper) to rebuild?
I'm too old to ride anymore but still have my CR500 2 stroke to fill my garage with that beautiful smoke and sound. Sounds way better than a flat 4 stroke fart sound.
Gotta compare the husky 250 0r 300 with that 450 fx or wr. better apples to apples comparison.
