Perhaps after a few years of DI, more work can be done developing them and tuning them when they emerge in racing for example.

Two strokes need something to start back on again, at least they will start again with something. Nothing happens overnight. Kaaden didn't stop developing chambers through all his difficulties, he could have flopped because it was difficult to start off.

The most highly tuned engines are rarely the smoothest. Imagine the potential in the future, after development wait till they get multi-cylinder designs rolling!

How will any development take place if people mention "It's D.I. it's not the same as it was" that is what will harm the two stroke much less a smooth powerband. Nothing's the same as it once was, at every moment in the world, things change, if we don't, we get left behind, so we may as well make the changes our way.

It's up to us, fans, designers, technicians, racers, to make it happen.

Generally, variable exhaust and intake geometry limit maximum flow of gas that would otherwise be attainable. For example, traditionally, Disc valves offered more maximum performance over reed valves. Two stroke engines of the future may well use variable geometry, but variable to different degrees...They need not be the same from scooter to sportsbike to enduro. The exact same throttle bodies and butterfly designs need not be fitted to every single D.I. two stroke. Mechanical limitations always apply regardless of "the evil/magic of the computers!!"

Even if sportsbikes were restricted, who's to say people could not develop components and systems to make the engines shine! People, especially over a certain age, fear the electronics and the advance of them (no pun intended), when you consider that the average person is likely to become more computer literate in the future, I see that in a small way, power can be given back to the average person/enthusiast as the cycle comes back and we understand what we are dealing with. It's up to us.

Direct Injection is the future

Direct injection 2 Strokes creates a 4-stroke powerband. For most people that is better. But like you many people like that hit. With DI you can have different power curves. It is possible to make a powerband that is narrower than a current carb 2-stroke! Aprilia made a DI RS250 and did this. They had easy power curves, aggressive curves, and curves that emulated carbureted 2-strokes. it would be very easy to have a switch on the handlebar that let the rider choose between them for his preference. Say if someone made a V4 500 Motogp(Sport bike) 2 stroke with Direct injection, You can even make it harder hitting than the current carb 2 stroke sport bikes or make it smoother like a 4 stroke and the emissions are lowered to 80 percent on the Direct injection and the 500 V4 motogps where making 210 bhp in 2001 imagine how much more it would have with Direct injection

Thanks but everybody says the the yz 125s have no bottom end for trail riding because I'm going to be trail riding for a whole week at camping

Yes but could I race them in those classes like could I get sponsored racing a KTM 150sx in those classes?

I'm 5'5 and I weigh 125 pounds and im 15 also could I race this bike in the 125cc class or the 250 4 stroke class in America in Michigan?

Is it good for trail riding and if I get a paddle tire for sand dunes will it be good?

General Two Stroke Talk / Getting first 2 stroke dirt bike

« on: January 31, 2011, 08:53:15 PM »

I'm 5'5 or maybe 5'6 and I weigh 125 pounds and I'm 15 and when I was 14 I rode a 185 4 stroke dirt bike in a 74 cr 125 frame. It was kinda scary going past 3rd gear because I was not used to the power band or speed. It was really a 185cc 4 stroke engine that came off of a old honda 3 wheeler. I want the best and fastest 125cc there is mostly everything Ive rode was a Honda. I want he hardest hitting powerband and speed and good handling and suspension. I'm looking at a Honda CR 125 or a YZ 125 or a KTM 125sx the years for the bikes that I'm going to get are from 2000 to 2005. I heard that the Cr 125 had a weak engine and the YZ 125 is a blast to ride and the KTM has the most power and the hardest hitting powerband. Witch is the funniest one to ride. The CR 125s look the best though to me. I want power thats what makes dirt biking so much fun! Ive rode a 350 raptor before but no where as fun as Motocross! Ive rode that 185 4 puke in the trails in Michigan

Alright I want to race motocross next year and I either want the YZ125 or the YZ250. I'm 5'6 and 125 pounds and I'm 15. I was scared to go past 3rd gear pinned on a 185 4 stroke dirt bike but that was a year ago. Will he YZ125 have the torque of that 185 or alot for me? I always hear the 125 2 strokes don't have any torque. Ive never been to a MX track I don't want to scare the hell out of me either or have a to heavy bike
