And the cc advantage. At the time the yamaha yz400f got a 150cc boost over the 250s. 2 stroke riders hated it right away but it was way easier to ride with the torque it had. Between the cc advantage and the EPA it was just easier to make 4 strokes. It's funny that all dirt bike magazines are reflecting on the mistake of going to 4 strokes and how much they cost over comparable 2 strokes.

[@yamahaexpert]

@@StepstoPodium Neste momento (felizmente) estamos assistir um "reverso da medalha" no que toca aos consumos de um 2 tempos com a introdução por parte da KTM de injecção direta ao cilindro, permitindo reduzir até 70% os consumos e 50% as emissões comparativamente a um tradicional carburador. E sobretudo, as perdas de potência sao minimas (para já), coisa que nao deve demorar muito a mudar.

[@StepstoPodium]

tem cuidado porque a ktm não é injecção directa! A injecção é no transfer port, daí chamarem se TPI. A injecção não é feita na câmara de combustão e esse é das maiores limitações da ktm em tornar as dois tempos parecido com as 4 tempos mas vamos ver o que a inovação nos trás 😆

[@3SPR1T]

That what you showed wasn't inertia, it was gyroscopic Precession. Rotational inertia is the effect you describe when a rotating object doesn't want to change it's angular speed.

[@StepstoPodium]

Thank you for spending the time to give some feedback! I knew this question would come up sooner or later :P I excluded Gyroscopic Precession for a reason, you have a fixed axis of rotation (both wheels on the ground impose a rotation axis). Besides that, although we are used to handle rotational inertia in a planar context, we also have rotational inertia in a spacial context where the inertia matrix can explain this phenomenon. I did my research and these were the conclusion I made and I'm pretty positive it checks out! but if you have any other points of view, please let me know, I would be delighted to go back and forth on this :)

[@3SPR1T]

​@@StepstoPodium But this effect still hasn't to do with the rotating inertia of an engine. (except for the wheels that keeps the bike upright) I think a better way to explain that would be a flywheel. When you try to rotate a heavy flywheel you need force to get it moving, that's what defines mass and it's also hard to stop a free spinning flywheel (resistance in change of motion). Just like the added mass of a camshaft, cam-chain etc. Procession on the other hand works only when you have a already spinning mass. You have no procession on a still bearing BUT you have still the resistance in motion when you try to get the bearing spinning. Inertia is always there procession is not. ;D

[@StepstoPodium]

Like I said, in this case the procession is not the explanation because one of the necessary conditions is not met. And the example you gave about the fly wheel only explains what you are stating, not the resistance in orientation change, which the spacial inertia would explain

When a top 2t rider went down the classes normally part of retirement, they would floor the 4t feild.

2 strokes are not easier maintenance and less expensive, cuz u rebuild them twice as often and spend a lot of money on oil to pre-mix with your 25mpg if u ride a lot. Even the TPI fuel pumps have to be replaced at 65 hours. Carbs are always maintenance and drama, jetted wrong/need cleaning; then theirs power valve adjustments and dented pipes. FI 4 strokes need the valves checked once a riding season if not racing, and go 200hours/5000 miles before a rebuild equaling or beating the cost of riding a 2 stroke that much, plus the hours not spent on maintenance.

2T is powerful cuz of the Power Valve... Tho the F1 engineers came up with the idea of making 2T F1 cars cuz they are lighter, faster, more powerful and more durable. The problem is that they want to make it with direct injection and high rpm... that isn't a problem for 4T but it is for 2T because lets take like 18000 RPM which means that in 4T the injection valves open/close and get a slap of heat 150 times a second. They can endure that... but 2T can't because it does a complete power cycle with every up/down the piston does so that would mean that the valves would open/close and get a heat slap 300 times per sec. So the engineers need to figure out what material they should make the valves from that will endure that much heat first.

2 strokes forever! The only pain in the ass with 2 strokes is that you can't do engine braking... well, you can, unless you want your engine get screwed up...

[@Noeman2009]

I had 3 2-Stroke motor, Yamaha underbone, Vespa and Peugeout Bhama. It's fun riding them. Hahaha

[@wisnuprasetyo1207]

that why i never sold my NSR 150 SP, 2 stroke is never die

[@manmohankaur2776]

2 strokes....no cams no valves no headaches.....'nuff said😂😂😂😂😂😂😂

[@fuego_jonny6528]

I love the freaking outlines he does for the engines (like we’re looking inside)

[@sciencemilitia1853]

2 strokes are way better.

[@Maplicito]

It's a little misleading to equate "a 4 stroke's power stroke is more powerful than a 2 stroke's power stroke" with "a 4 stroke is more powerful than a 2 stroke". Your bike is moving through all the strokes, not just the power stroke, and every non-power stroke is lowering the power/stroke ratio. A 2 stroke makes power in half of its strokes while a 4 stroke makes power in one quarter of its strokes. Whether you're on the 2 stroke or 4 stroke train, you might as well be accurate.

2 stroke Reeves you're heart

[@lukewarmwater6412]

honestly. I think that I have been seeing the 2 stroke become obsolete for my whole life. two strokes used to have the better horsepower to wieght ratio, but these days we have 4 stroke snowmobiles that put two strokes to shame, so this is obviously no longer true. you can put a modern 4 stroke any place a 2 stroke used to go..... stop saying 'explosion' when you mean ignition. there is no exposion. there is a controlled burn. gasoline cant burn fast enough to explode. what I mean is it is not an explosive. it does not explode. pistons would be destroyed if it did.

125cc 2 stroke bike is more fun to ride than a 500cc 4 stroke bike the sound, the insane powerband of a 2 stroke it's just more fun to ride.

[@holeshot1721]

4 stroke if u wanna ride out of the woods! 2 stroke if u wanna push your bike out of the woods!!!!

[@fisheyelens876]

Well, does anyone know if there is any four stroke bikes out there that weigh 280 lbs and put out 190 hp?

[@andrewkacz7924]

A 4 stroke is alot more reliable but a 2 smoker is alot better for a woods bije and hill climber

[@RickyGuterson]

The one that does twice the rotations for the same amount of work is absolutly not more efficient. You forgot about all the power lost wile having to rotate all those extra parts. lol The record for most power per displacement Isn't a a 4joke and it never will be.

[@weeniehutjr1718]

And 4 strokes last longer

[@SD-ir1vf]

You think so. I have a CR 2T. 1986. 35 years old still runs good.

[@weeniehutjr1718]

@@SD-ir1vf probably take good care of it, don’t ride it hard/not racing it, and probably don’t ride it much but nice

[@michaelosullivan8288]

2 stroke should not be made and that's why we got more 4 stroke build more then 2 strokes and that's why government has to plan to stop make more 2 strokes on any bike/quads and there so many many kids gets injured from 2 strokes power and glad to see more 4 stroke never give up like 2 strokes and I never like 2 strokes and I'm always 4 stroke person
