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

[@joshuavanzuydam5044]

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.

[@michaelnutzel2226]

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.

[@Mockle07]

@@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.

[@michaelnutzel2226]

@@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.

[@Mockle07]

@@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.

The husky seems to be catching the yammi even with slower starts.

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.

[@robertwright4336]

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.

Everyone in my family has always ridden 70s-80s bikes. I was just a kid when the YZ426F came out, but we went riding with a guy who had one, and he was very confident in having the best bike in camp. My dad was riding a 1978 Maico 440, and my uncle was on a 1981 Husqvarna 430XC, both air-cooled 2-strokes. Those old guys ran the YZF ragged. His power was almost a match for the Husky, but the Husky had a 6th gear that ended the conversation. The Maico simply had more horsepower than any other machine in attendance, and did serious damage through any kind of corners.

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.

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.

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)

[@leftyeh6495]

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.

If you are a good enough rider the 250 two stroke will smoke the four stroke 250.

[@wmden1]

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.

I'm a kart racer... it'll always be two stroke for me... not to mention the smell of R30 :)

[@aggressor6609]

This only proved that the Yama is an excellent 4t for keeping up with a bike that revs pretty much twice as much.

[@pauloakes6952]

4 stroke bikes rev higher than 2 stroke. 15k vs 10k

[@midsouth2strokes185]

I was raised on a 2 stroke and little has changed for me! However they do make some nice 4 strokes now.

[@haroldfleming9908]

I'd rather have the two stroke when that timing chain breaks and destroys the engine. Can't hurt that 2 stroke.

[@alienfromarea5115]

My opinion of 2 stroke vs 4 stroke depends on what i am riding

[@sam-mcginn]

We need ktm killer ep 4!!!

[@randallmason9687]

2- stroke for life! 4- strokes are great, until you have to pay the price of a rebuild!!

[@fimenduro]

Next time try a sandy uphill, the 2-stroke will shine because of 30% more torque.

[@gladegoodrich2297]

Honda, Kawasaki and Suzuki are missing out on a lot of sales and profit. Yamaha and KTMs cleaning up!

[@evangoldstein5866]

I grew up with a CR250 , and RM250 when mono shock first came on to scene. Two strokes were the best.

[@reddevil331]

2 strokes for life!🤘🏻

[@Chroma_noha]

This was not a balanced duel, 250 2t is stronger but the video was interesting and well shot and both bikes have their charms.

[@alinn.4341]

I think the biggest diff is that one of the riders is better :)

[@tudorcotoi7011]

You should have raced the Husqvarna with the YZ250 ;)

[@wealth_forge]

Did that bike just stand up by itself?

[@randallkipker9990]

Great video… !

[@richp5321]

2 stroke sound all the way!

[@rcracer641]

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.

[@jamieallen5313]

Nice bro. Got the same husky 250i. 136 km is the fastest I’ve had it goin. Full fmf pipe is only difference

[@polarbear751]

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 👌

[@bedestapleton2417]

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

[@surronstuntz3146]

I thought I was common knowledge to compare 250 2strokes to 450 4 strokes becuase of the power

[@Mockle07]

Well they don’t in enduro racing... in Enduro GP 250 4 and 2 strokes compete against each other directly and the results are always very close.

[@stuntroll5363]

@@Mockle07 He compared a 250 vs 250. The right comparison is 450 4 stroke vs 250 2 stroke. Or compare a 125 2 stroke vs 250 4 stroke. His comparison wasn’t valid.

[@Mockle07]

@@stuntroll5363 read my comment again, then explain why the comparison is not valid.

[@SPCRacing1]

That comparison started years ago with the Japanese bike companies heavily influencing the AMA to create the double displacement rules. It was stupid then and it’s stupid now. Race equal displacement.

[@brad8179]

250 4 stroke is equal to 125 2 stroke 450 4 stroke is equal to 250 2 stroke and has always been that way when did they start comparing them like this. Do people even know how the 2 bikes work? The 250 2 stroke is going to beat the 4 stroke every time

[@erichitchens29]

That accent and the way you was talking had me dying the whole video lol

[@adam-cw2on]

Love your vids

[@nickbishop6174]

good vid mate

[@davidnobular9220]

Ahhh...the old 2 stroke vs 4 stroke.....Imagine having to rebuild a 4 stroke at the end of every race without a Factory team of mechanics ? F8#$k that !! Some people like doing that, I know. Also, I understand that with current tech (ie fuel injection, computer controlling and stuff) a two stroke can be made quite efficient (take THAT Euro Greenies)

[@6stringzjoe]

its not the bike, its the rider

[@ian.v.channeltv7432]

Tested and proven even in dragrace in underbone same CC 2stroke always win

[@user-Terracer]

As an old two stroke guy let me say that the two stroke walking away from the four stroke doesn't surprise me one bit as a two stroke makes power twice as often as a four stroke. HOWEVER, when the terrain is more than just a plush grassy field (like say a motocross track) a four stroke is more tractable than a two stroke, which will usually equate to a quicker lap time. The explosiveness of a two stroke's power makes finding traction much harder, which begins to affect everything else from the choice of lines around the track to a rider's fatigue level. The big problem I have with the new four strokes is the cost of maintenance. Compared to a two stroke it can be a problem for many new riders and racers. For instance, a KX450 Kawasaki calls for valve replacement every 25 hours - if memory serves - and they are NOT cheap. You could rebuild the top end of a typical two stroke at least twice for what the valves cost! Give me a two stroke!

[@easternyellowjacket276]

I'm surprised the WR did as well as it did against the 2 stroke.

[@alanjm1234]

On dirt, it's as much about traction as it is about power. But you could see the two stroke was much faster later in the runs, where power mattered.

[@homer97027]

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.
