what happend to the 2Ts

[2strokesrock]

Oh come on this is a two stroke forum and we are authorized to talk about 2Ts all we want.

P.S I know im new to DRN so my opinion dosent carry any weaght but gimmie a break.

Pred is to threads about two strokes what mosquitos are to bright lights in the night.

It's the motorcycle business and for most companies, two-strokes just aren't good business right now. It's nothing more complicated than that.

If that changes then the available choices might also change, but there isn't anything on the horizon that would lead anyone to think it will happen in the foreseeable future.

Rich, what's your estimate on current GP level power? 125's 50-60hp? 250's 100+?

Luddites -bah humbug! I'll keep smoke'in till the parts run out, then weld the scraps back together and smoke some more :nener:

 

[XRpredator]

so not only technologically irrelevant, but economically non-viable!

bigfoot told me so.

Based on what I've seen I would think it's closer to 47-52 on 125s and 95-103 on 250s. Even that might be overly optimistic.

Do you believe everything your brother tells you? :)

I was at the arena cross race last weekend and was talking to the owner of Lancester sport cycles and asked him about yammies 2-stroke. He told me that they were saying 2010 was gonna be the last year. But nothing has been said for sure.

hmm, an authority no less than Kevin Cameron said in the September issue of Cycle World that the 125 GP's - and i paraphrase - "put out in excess of 60 rear wheel horsepower".
As the 125 is essentially 1/2 of the 250 i'm thinking 120 hp for the 250's is right on the mark. If 250lbs/120hp power-to-weight ratio is irrelevant....
anyway, KTM is set to revolutionize motocross with their DFI 2 stroke. i heard it will be a 2010 model

Well then someone at Suzuki owes me an explanation why my sons RM125's put out roughly 35 HP and my RM250 only put out around 50. I can't believe those idiot engineers at Suzuki forgot to include the extra 20hp on my RM250 no wonder I went to a 4 stroke!

That's not really what he said, and it was more of a throw-away statement to show comparative context in an article about vintage machines.

The difference between the 50 horsepower that KC and a lot of other smart folks were claiming 125 GP engines were making just a few years and the 60 hp mentioned in the above piece is about a 17% increase per square inch of piston area. That is an enormous increase on an already highly developed engine technology that hasn't changed significantly in a very long time.

That said, if KC says that they make that kind of power, I'm smart enough not to argue the point. Hopefully he'll do a TDC column that goes into more detail on the current two-stroke GP technology. He certainly would have a big audience for a column like that. With GP 250s going to 600 four-strokes it seems logical that he might write an article that compares the relative power outputs and the methods by which they are achieved.

I'll believe that when I see it sitting at my local dealer. I hope you are right, but regulations in some of the EU countries are making life really difficult for the manufacturers, so you might want to wait a bit before putting down a deposit on one. ;)

Umm, how many cylinders are on them 125 gp bikes????

125s are singles and 250s are twins.

 

[whenfoxforks-ruled]

That is some big numbers on a 125 single. And it lasts at least one race!

 

[whenfoxforks-ruled]

I was looking around and ran across Swedetech engines, hit him up on some dyno charts on the 125 cr engine, and then the this site, http://www.factorypro.com/dyno/true1.html , staggering numbers on them big bikes!

 

[2strokesrock]

I hope KTM suprises us with an awsome two stroke.

 

[XRpredator]

keep hope alive!

 

[Rich Rohrich]

keep hope alive!

I'm hoping Bigfoot will be riding a Benelli MX bike in the 2009 SX series. :whoa:

 

[Daf]

I like the 2 strokes - I hate to see them disappear. :fft:

Hey - check these 2009 Maico 2 strokes! Can you imagine hitting it with a 685cc smoker?? Yow! :yikes:

[2strokesrock]

Wow! that looks like a vary vary light 4 stroke. is it? benelli makes some awsome shotguns too!!

 

[2strokesrock]

Maico!!!!!!!!! there still makeing dirt bikes!!!!! sweet! I hope there more reliable then they used to be.

 

[Panhead]

I ain't scared of no 4 stroke. Come and get some of this K5 hunney. Your tecnilogical 4 stroke can eat my roost.

The K5 is :boss: . Thats right! :nod:

 

[2strokesrock]

LOL. Awsome bike!

 

[stumanarama]

You really want to stick such a big American icon on a chinese bike? :coocoo: Please, Bigfoot should ride something big and American such as a Harley, or an Indian, or a Harley chassis with an Indian motor!
:laugh:

 

[whenfoxforks-ruled]

When did Benelli turn chinese?
