2 stroke vs 4 Article
- Thread starter gaser
- Start date
Good read-
Was that current? Didn't see a date. Just curious.
I have a 450/4 that I kind of like and want a new 250/300 "something" and was leaning 4-stroke, but the repair/maint issues do concern me.
I love the power delivery of a 4, but know that new technology can make a 2 feel like a 4- in regards to maps and such; just smoothing out the peakiness a bit.
My 200/2 is, well a 2.... it'll dig a trench, whereas my 450/4 is like a tractor and will just chug up and over anything.
But, for somebody that doesn't do their own maint/repairs(me)....... 4s is $!

Good article. This is not the first time I have heard that Honda is to blame for the demise of the two stroke in AMA racing. The silver lining is that it leaves the door open for Gas Gas to take advantage of the hole in the market.

He didn't even get into the whole noise thing which is another whole issue. We were recently at a friend's house waaaay out in the woods and there were two guys riding on a moto track a couple of hill and hollers over from his place. This in middle TN, northeast of Nashville. One guy was on a 4T and another on a 2T. To begin with, we thought that the guy on the 2T was farther away but realized they were riding together. The 4T sound carried way farther than the 2T sound.
I think the Euro companies will revive the 2 stroke!

If some of you are old enough to remember, Honda was the last manufacturer
to make a 2 stroke back in the early 70's, when they made the Elsinore. For some reason Mr. Honda had something against 2 strokes from the beginning.
I didn't get to read the article because its blocked here at work but I will check it out when I get home.
The sound issue of the 4 strokes is a very major problem. And the mfgrs and after market companies don't seem to be doing anything about it. They say they've got the level down to 94db but that is at basically idle, which defeats
the purpose. The industry needs a more realistic measurement but the ol' cash cow would go away.....

He quotes Brad Lackey as comparing it to his 2010 RMZ450, so it can't be too old.
It's hard to quantify fun, but I just about fell asleep riding a CRF250 at a moto track last year. I was there with a guy that owned that bike and my old YZ250, and he wouldn't even let me ride the two-stroke until late in the day when he was spent. The Honda was available because, well, he simply doesn't ride it anymore.
If you get a chance, pick up the latest copy of Motocross Action. I don't usually read this but the article on a 2001 Honda CR 250 caught my attention. Read the ENTIRE article. The conclusion is, 2 strokes are a lot better than anyone cares to admit. In this case, the 450's might still win at the pro level but for everyone else a 2 stroke makes a lot of sense. And no I don't hate 4 strokes, an old XR, TT, DR can be just as much fun as any other bike. Just my random thoughts.
well, i find that most interesting, this article.
it made me even more convinced that i made a good decision in going for 2stroke.
all i would like is for mileage to go up ,and even more quite.
noise i can do something about it,but mileage not really...
torque and performance-wise is all good.
i hope they make cleaner 2-strokes in the near future.
i allso hope more and more people try out the newer 2 strokers so they can feel that they're not all that peaky anymore (at least most of our gassers).
thanks for posting this gaser!

What year in the US did they "ban" the sale of 2 stroke bikes for the street? I remember growing up several people had the Yamaha RD350's, RZ350's, etc along with the KE100, and other large 2 stroke street bikes like the Kawasaki 500 triples, etc.
I guess if you still owned one you could ride it no problem. Was the ban in the mid 1980s?
Oh, wait, never mind... the Chinese 50cc 2T scooters are everywhere. Along side the Yamaha riva, Honda spree, and all the other 2T. I saw a vintage Yamaha DT50 the other day, mint condition for $700.
I sold my KTM 450 and switched to a GG300. Best move I made. I can ride this bike far better and easier than the 450, it doesn't wear me out as much.
I can also spit the cases if I have to and not need $500 in special tools as with the KTM. Don't get me wrong, the KTM is a fantastic bike. But as far as $$ wise, the 2T just makes sense.

They never banned 2t's for sale just manufactures found it to expensive to get them throught emisions on high performance bikes. Scooters are almost all two-stroke and they are 100% legal.
2T vs 4T is a hard thing, I've said it before and will say it again, if I did moto and didn't race in the woods I'd ride a 4T hands down. The 4T just works better on the track and is easier to put down good consistant lap times. I think the 2T's work better in the woods however. Snappier response and weight make the 2T work better. I think you can get a better instantaneous jump of acceleration out of the 2T also that the 4T just can not produce, that jump seems to work in the woods when tight also.
Don't know how to explain it but it seems that 2T's the throttle controls how fast the motor revs and 4T's the throttle controls how fast it will rev and how high. No matter how perfect a 2T is jetted since this can effect the reving the bike seems to rev through the range. A 4T seems to have to have throttle wide open to rev through range and that seems to not work for me.

I'm pretty sure there was an outright ban on any 2 stroke street bike over 50cc implemented in 87ish. I think it was that way to allow mopeds to still be sold but nothing more than that. I think that ban is all inclusive now. I could be wrong though.
Anyone who likes the wide power spread of a 4 stroke only needs to ride a GG 300 2 stroke.
Nuff said.

I've heard people say two-stroke street bikes were banded but I can't find anything that says it anywhere. Its just a matter of emisions as far as I can see, with a few states such as California and others trying to ban two-strokes alltogether. Several manufactures as I type still have street legal two-strokes. Some mopeds and at least a few larger than 50cc's I know. I've been wrong before however....lol

I'll always own a 2 stroke if for no other reason than to annoy the EPA and the bark humpers.
DUDE! Bark Humpers!!!!! I'm using that!
