125 Two-Stroke vs 250 Four-Stroke Battle at Redbud Motocross 

Lol same that 4 stroke loud asab

Yeah same heree

Best comment on the thread! I have a CR125 myself and wouldn't change it for the world. I personally prefer 2 strokes aswell I just love the power band. At night I hop off my true love (my bike) and ride my yfz450 like a bat out of hell and have more fun than any dude drinking or talking senselessy at a bar or out on the "town".... some of these city folks really need to just shut up and ride man!

+The Truth amen to that brother

Amen

MotoGoProVids sooo true bro... I'm the same as you,, I prefer 2 stroke over 4 stroke but I still have no hate over 4 strokes. I will ride a 4 stroke any day,, and I will ride a 2 stroke any day it's just I prefer a 2 stroke

MotoGoProVids thats true

Hahahaha

Hahahaha

Hahahaha

hahaha me too

because your in bad shape ;)

Umm. You must be professional then. Or at least you try to represent pro.

both are badass riders

Same, I ride a 2-stroke but I don't hate 4-strokes. We should all just ride and get along.

***** I ride a 2-stroke, because they are so much fun to ride. The power band is just so much fun.

i ride what i find on a deal lol

I'm just afraid 2 strokes blow up too easily, from what I heard. I just got rid of a 2004 YZ85 ive been riding for 4 years, and it never blew up. Over the winter I bought a 2002 EXC 400. Haven't rode it yet, though.

+XPWNZERX Welm its the other way, Just think whats the different between 2 and 4 , And also, 2-strokes can be ridden for years without changing piston onge if you handle it the right way

Kurosaki990Ichigo thank you people don’t really know how to enjoy things on the internet they just like to bich about everything besides watching and enjoying a nice race

Thank you same

Ryan Otto same i like both id take any but 2 strokes just don't have the high end torque like a 4 stroke

BillyBob Keith I no h8 m8

BillyBob Keith Same here , they both have their place ... Two stroke when I wanna haul ass... Fourstroke when I have to mow the grass.

Same, i love both, but i think i like little more of 2 strokes.

Good comment,, totally correct.

right in every way possible

easier said than done

Yes momentum in the turns. Should stay on the gas. Both guys can ride tho.

Only 2 reasons to rev while in the air. 1 is a panic rev, for those situations where the bike is kinda nose down while in the air, it will help bring the gront end up a little. 2 is for better landings. It can help if you're landing crooked, and will help the bike to deflect more of the impact. It will keep the bike from bouncing around after a hard landing.

***** What I am saying is correct.A 2 stroke appears to have more torque because I get to fire every stroke.I am computer a 2 stoke engine power to the 4 stroke for every combustion they get to make on their revolution not a buck of revolution combined.Of course a 2 stroke is going to win but for the 4 stroke to even come close to the power of a 2 stroke it has to pack a big punch when it does combust thats what I mean.

You know what I meant.if you were to compare a single combustion of a four stroke and a two stroke the four stroke has more power but because the four stroke does not fire every two stroke the two stroke has more combined power.For the four stroke to make up for the missed stroke it has to produce a lot of power in that one stroke it does produce to push all those heavy parts.Its shows you how much power a 4 stroke really has.

***** I know that all I was trying to say,but you have to be honest 4 stroke engines last way longer then a 2 stroke engine,and you have better control of the rmps.With a 2 stroke the only way I can describe it is like a on and off switch.You either have it at full power or its nothing.With a 4 stroke it has power through all the rmps and its way smoother.

Malik Berry I agree completely but it all comes up to what you love and want to ride. 2 strokes or 4 strokes are both good.

Malik Berry compare the price to fully rebuild a 250 4 stroke and a 125 2 stroke. And in all means yes the 4 stroke will last longer but the 2 stroke can be rebuild in a day

Tide Pods QUADS ARE FOR PUSSIES

lol I still think that is the sound after hearing 2 strokes for over 25 years

+Jimmy Connor b

+Elmin Jusić b

Hahaha you think that because never use this machine in one race

I call em bees cuz they sound and are deadly

Hahaha, yup

I finally bought a 2 stroke still haven't got to really brapp on it yet because I'm waiting on parts. The only thing I do dis like though is the mixing oil and gas and how loud the bike is I wish the sound was a little less intense. I love my ears. Another thing I noticed the neighbors seem to hate my 2 stroke way more than my 4 stroke I think it is the aggressive sound it gives off.

@@Micscience Yaaay. Good for you bro. You'll be brapping in no time. You can fix the bike yourself, unless it's transmission you can fix the top end in your garage. No timing chains, no valves, no excess BS. 😉😆 As for the sounds, it IS a more aggressive one, like A REAL racing machine should sound. If it's exceedingly loud though, repack the silencer. They make lots of kits where you can do it yourself. You'd be surprised how much lower the volume is over that's fine, plus it increases the low end snap. Hit me up if you have any more questions. I know local Pros who are hanging onto 15 year old 250 2 strokes and doing well on them. Train though, 4 strokes don't scare you so your not relaxed. A slow 2 stroke scares you cos it's hyper and aggressive. Cycling us a good way to build cardio and lung strength. Best ff luck and "rubber side down" ... that's a racers blessing. 💪🏻😎💪🏾

@@Micscience oh yeah, mixing. Manuals say 32 to 1, 4o or 5o to one is best. Check your plugs often, a nice brown to tan color is perfect. Braaaap

Well wouldn't have to exert less energy if the heavier bike plants into the ground better you are not dealing with controlling the bike.

@@vetb882 I did it at 32-1 I did notice it was a bit smokey.

The fony

Yep

good analogy

Wow i had never heard that

@@damiondominichumble5410 you stupid as fuck two strokes rock

Straight up badass is what you are.

+Michael Marsden I'm only 6 months and ride a YM250.

There's a 7 year old that rides a cr500

+Michael Marsden TUFF!

I'm on 11 and I ride a 50.

Why

+Doug Anderson do you often go around making yourself look stupid, or is this just one spontaneous decision?

I think I get it. There's things that you will learn on a 2 stroke that 4 stroke riders dont typically deal with, and over the long run, it makes the 2 stroke rider a more complete rider. It's like this episode of Pokémon, where Pikachu and his trainer Ash battle someone who also had a Pikachu( but forced it to evolve into a stronger Pokemon, called Raichu). Raichu has all thebpowers of Pikachu, and is supposed to be stronger, and potentially faster. Well Ash's Pikachu mopped the floor with that Raichu, because his Pikachu never evolved, he learned new moves that the Raichu didn't know. Ash had a more complete Pikachu. Ok. I'm done with my analogy.

Hahahahahahahahaha omg I am dead right now brooooo 😂😂😂😂😂😂😂

+Silicon Toad hahaha this is the best shit I have read in a while 4 stroke all the way

But 2 stroke is the way to go

+Cyrus Moss It is! check out my brothers vid its a short race but its worth the watch because the 4 stroke got dusted... 1998 cr 250 vs yz426 I'll edit the video description after i see the mistakes...... lmao

SupremeTalkShow 420 Depends on the riders skill too. This whole 2 stroke vs 4 stroke debate is old and pointless. 2 stroke - 30% more power - LIghter - Cheaper to repair 4 stroke - Not as insane - Heavier - Better on hard pack dirt - expensive to repair but not as often I'm not bias, I just prefer 4 strokes because of a couple reasons. I like the weight I dig the sound And I don't ride chainsaws :) (My poke)

Buy ktm two stroke Fuel injected motocross motorcycle. It's already in few market

Fuel injected 2 strokes are retarded stick with carb

David Pelkey why

@@xkxmdmdnxjx9885 they arent that reliable. This chick has a Husqvarna 150 2 stroke. Bought it brand new this year, and has fouled more than 30 spark plugs this year. She just had to replace 3 in one day. Husqvarna even sent a specialist out to look it over, and the specialist rebuilt the engine for her, and the problem is still there. It's a good bike when the plig isn't fouled. But she also does a lot of trail riding at slow to medium speeds. Meanwhile, I bought my 2021 yz250 2 stroke in February, didnt get to ride until mid April due to rain and work. Anyway, Im still running the same spark plug that came with the bike from the factory. Still no problems, and I think I have about 80 hours on the bike and spark plug at this point.

KTM, Husqvarna, GAS GAS, all offer fuel injected 2 strokes, with electric starts. Btw, KTM owns all of those brands. The GAS GAS receives ktm parts from about 2 - 3 years ago. It's not as new as the Husqvarna and KTM, but it is still new. They treated it like how Ram trucks has the ram 1500 and also the 1500 classic. The classic is basically the previous generation ram chasis, with updated lights.

What? Where did you hear that?

MxQuestion572 Read your 2015 AMA rule book under Motocross/Supercross! Also the FIM rule book under the same heading.

Till Schnur sounds badass

Well thats because there is double the metal inside the engine of a 4 stroke and it takes more time to complete the cycle. Also all 2 strokes have an advantage they have expansion chambers which 4 strokes don't have. You would need to add a turbo or a super charger onto the 4 stroke to equalize the extra performance effect the expansion chamber gives a 2 stroke by using sound.

Micscience yes

@@Micscience the expansion chamber acts like a turbo but it is not anything close to one

@@SL4US You may be right but the term (ride the pipe) has some truth to it. It seems to dramatically change the performance of a 2 stroke. When you are not on the pipe on a 2 stroke there isn't much there. I might put a straight pipe on my cr125 and see if it loses a lot of performance.

+Elias Boyle Best answer for this stupid debate in years. I like 2 strokes because they are easy to work on. Perfect.

+Silicon Toad is that sarcasm? They are... Although easier to blow up too xD

+XPWNZERX no I doubt he is sarcastic

+XPWNZERX Considering what he said is true, yeah. I could also rebuild a 2 stroke 8 times for the price to rebuild a 4 stroke just once, and you can bet your ass a 4 stroke isn't going to go as long as a 2stroke on it's 8th rebuild without having to be rebuilt the 4 stroke.

Yeah and it's actually a myth because they are pretty equal.

I'll second that one. I own 3 2-strokes. When I get old and lazy,I'll get a 4-stroke dirt bike. There's nothing like the explosive power a 2-stroke has. Its all about the excitement!!!!!! Different strokes for different folks lol!!!!! Enough said.

I owned a Raptor Big bore 660 to 735 for 5 years and NEVER rebuilt it once.My CRF 450R that I have owned for 6 years and I have NEVER blew my motor ONCE. I only had to replace the piston and rings because it was going out of spec and shim the valves. Mind you I did it ONE time. The Top end kit for my CRF 450R is only 30 bucks more then a two stroke with ALL the gaskets, piston, and rings. I've never lost compression because I don't hug the rev limiter. 4 strokes are bullet proof as long as you do simple shit like changing the oil frequently, clean the air filter after every ride or two, and don't rev the guts out of it the motor will last years and years and years without any sign of a rebuild. You can't beat the constant torque and power of a four stroke, they are so much faster and you don't have to hug the rev limiter all day in order to go somewhere. I got power from idle all the way up to red line on my bike, and on 2 strokes ONLY have power in one place, the top end and I utterly hate it. It's "bog bog bog bog wah - shift a millisecond later - wahhhh- another shift and before you know it you're topped out while the 450's and 250's still got one or two left with the much longer gear ratio. Plus I like how the guy on the KFX 250 was probably hugging 3rd gear the whole race, instead of constantly shifting.

Wrong, the new four strokes are much faster (although bigger displacement) and are also much, much less reliable because they have a higher compression. Also, there are a lot more parts on a four stroke, making them more complicated to work on. More stuff=more stuff to break.

2 strokes have a lot less maintenance then a 4 stroke engine.... Thats whats so great about them! no cam/cams, valves, timing belt/chain, etc etc.

yep

Marcus Koster Not to mention about 3x more expensive in parts, plus two strokes last long also. I ran one with the same piston for 7 years (shame on me yes i know) and it never had any problems.

gat dam ya i love em. Riding a 4 stroke fast is so much less work too!

You not watch the whole video? The 125 won...

+James Gingerich no no I did not. I read the description. must have read wrong. cool deal thanks for correcting me.

+ThorntonHiFi you are very correct indeed. I do understand however that it also depends on the type of rider. I ride but I'm not the greatest. I do understand what you are saying though.

2t is Beta rr300

U know it

Must be humiliating for a whole gate of 4 strokes to lose to a disadvantaged 2 stroke.

wi1pwoooiwiwwoi w I w u u kek.sp

yet 30 4 strokes just lost to a 2 stroke with half the ccs. fucking goof

Mrmoparrr I’d prefer an RM250.

Umm Honda’s 125 2 strokes where known for being ridiculously low in power compared to other manufacturers, they did make an amazing 250 but their 125 was pretty shit compared to the yz’s and kx’s

fucking agree with you man, its soooo much cheaper and EASIER to fix a 2 stroke than a 4 stroke!

Richard Caballero yeah but my ktm it is a 2 stroke I had alot of shot with that. While my 4 stroke kawasaki had barely anything wrong with it

Four Stroke is more power but a 2 stroke is fun if i had to choose for a race i will say four stoke they are more predictable

+Blue Rider25 no 2 strike is more power a 250 2s has way more than a 250 4s

+ENDURO SK thats not how it works, 250 2 stroke are in with the 450 4 strokes and i would know i ride a 450

+ENDURO SK 4t more reliable and 2t easy to rep :D

but they're really not. they just have kick at the end of the gear. they aren't any better than today's four strokes. and I never thought I'd think that way till I went from an rm124 bored out to a 141 , with all sorts of shit in it to a crf250r. now I love the crf I'll barely ever ride the 2 stroke again.

+dieselworld momentum.

outside is faster, inside is quicker

Kids these days

The shortest distance is in the inside however u pick up more speed keeping as straight a line as possible when hitting the apex (which research shows cuts down your time significantly more in the long run)of a turn which can lead u from the outside entering and to the outside exiting (this all of course depends on the track layout and if you are defending or over taking a position)

Good question, actually there are more answers, for example for the same power comparison, the 2 stroke bike is lighter but has less low end torque so is more affceted by accelerations and decelerations than the 4 stroke bike that also have less torque at the higher RPM. Another reason why the 2 stroke rider prefers staying on the outside is the engine inertia or engine brake, while the 2 stroke rider has to rely more on hand brakes and down shifts because the 2 stroke engine has a much narrow power band and less engine brake, instead the 4 stroke rider have more time to dedicate to corner entering and exting procedures because with the gas comand can manage the braking and doesn't have to shift as frequently as the other rider.

+Gustavo Moctezuma agree ahah

+alexis bouillere with half the motor, not sure how that's hilarious? if anything, it shows how powerful they are.

hilarious that with half the displacement it beat it 😂😂 so funny

AMEN BROTHA KINDA MADE MOTO-X A BIT SOFT

You should read this: motocrossactionmag.com/Main/News/YOU-ASKED-FOR-IT-MOTOCROSS-ACTIONS-TWOSTROKE-VERSU-7117.aspx

2 strokes are lighter, more horsepower per cc, and cheaper to maintain. seems like a no brainer to me...

okey, thanks :)

i've never ridden a 4 stroke, but all my riding buddies i grew up with and older guys, all who rode 2 strokes, say that you can't beat a 2 stroke. i have a cr250, but my atv is 4 stroke and it doesnt compare to the balls of a 2 stroke engine

InfamousMedia okey, i think im going to buy a 2 stroke :) but i dont know if i should buy a 125 or 250 because of my low weight. i want to buy a kawasaki or ktm is that a good choise ?

Thats how you ride a 2 stroke

If he shifted more on the straights he could of passed that four stroke. He was redlining way to much

ohh i guess i didnt see tht

And now the four strokes dominate motocross. Haha

TilDeathWeThrashard yeah, but only because of those ridiculous engine displacement regulations. 125 2's vs 250 4's and 250 2's vs 450 4's? Yeah, that seems fair...

PowerDudeson it is.

125's are not slower than 250 fart strokes. Same thing with the 250 2 stroke and 450 four stroke.

TilDeathWeThrashard To be honest, your comment shows a pretty heavy lack of information about motocross(if it's not just a joke, in that case my bad). The manufacturers "forced" the regulations to make 125 2t compete with 250 4t, 85 with 125, 250 with 450 and so on. The reason is, with the same cc 2t smokes 4t hands down and this is coming from someone how has zero preference to be honest. 4t have many advantages like higher torque no matter if you're at high or low rpm and stuff like that... If you exploit regulations and force the rulers to make everyone run with 125 2t against 250 4t it's obvious they'll drop the 2t and develop the 4t. That doesn't still mean that they're using it "because they're better". They're simply different and every true bike LOVER, not kids, knows stuff like this and rides wathever they can. For me, as an amateur, I am more comfortable with the 250 4t as it's easier to recover from mistakes and doesn't stress you that much...but my friends with their 125 2t are so used at always going fast no matter what, even in turns, that they smoke the others with their own 250 4t when they jump on them :)

Not sure about that, modern day 250f's are nudging on the 250 2t territory power wise. There's definitely a power advantage with a modern 250f compared to a 125.

yeah they are the 4 stroke tech has come along way

Skylor Brothers That is has, shame that the two strokes weren't given direct injection and more advancements. They'd still be the bikes to buy if they made the same progress the 4t did.

Yeah but what can ya do, life goes on

Skylor Brothers I heard KTM is actually working on a direct injection setup believe it or not. It would be very cool if we started seeing two strokes come about again.

xD no fucking way.

Haha your a silly galah

HAHAHHAHAHAH a 250f will never beat a 250 2 stroke idiot

That Moto Guy Are you fucking high?

Did you really just say that??? Lmao!!!

so thats why you get a 250 two stroke for twice that XD

haha yep pretty much

Exactly. 2 strokes are so underrated nowadays. Like i like both, 4 strokes and 2 smokes but cmon, 2 strokes AINT slower!

Then you've never rode a 450 if you think a 2t 250 has torque

TrevSkee Cannon 250s have 30 foot pounds of torque.. only 5 less than a 450

TrevSkee Cannon Then you've never rode a 500 2 stroke if you think a 450f has torque

Tikkikoira YES hahaha my uncle had a 500 I rode on the back when I was like 5 back wheel in every gear lol my 250 has enough for me though now that I'm 15

oBlair65o then yiu have not rode a 10000000cc dirt bike tell me how Much torque that has *just a joke*
