Looks like there is new life in the old engine configuration...

Oh boyz oh boys!!!! Two stroke power is like nothing I have ever experienced, I can never get enough. My only complaint has been the smoke... this is very exciting news.

Yea hopefully the 2 stroke isn't finished yet. I know 4 stroke snowmobiles just aren't near as fun as the 2 strokers.

Uh oh.....now we are all doomed to a lifetime of pictographs and old magazine articles.......

“When I look at two strokes I see only advantages – the power, the weight, the cost and complexity. And the riding dynamics of two-stroke 250s are very close to the 800cc MotoGP bikes. If I were making a sportsbike for the road I would choose a 500cc V4 two-stroke. I have absolutely no doubt it would be superior to the current superbikes, and be possible with existing legislation.”

A hybrid 2-stroke/4-stroke?

Poor Bimota doesn't want to hear this . Their Due 500 was intended to be a world beater but destroyed the company instead . Does my NSR50R count , with its terrifyingly peaky 8.5 HP ?!

Well, two stroke trailie bikes are a huge hit around here. People are actually reverting to them after experiencing the relatively high running (and repair) costs of the modern four strokes.
But I do not see much future for them. The writer is overenthusiastic to say the least.
True, they can be made as clean as a four stroke using various fuel injection technologies but at what's the point? Lotus made a 2000cc two stroke car engine a few years ago. It was clean (it complied with Euro 4 emission regulation), made good power and had more than good fuel consumption. Yet they still use Toyota engines on their cars. Why? Because it's much cheaper, end of story.
Also look at reliability: true, a two stroke can be rebuilt at a fraction of a four stroke but when's the last time you heard about a Fireblade or R1 engine seize? Modern four strokes may be complex but are incredibly reliable. especially when regularly and properly serviced.

Also the present license legislation in Europe completely killed off the 125 and 250cc classes, which were the main driving stimulus behind high performances road-going two strokes.
No, if I see a future for two strokes is in niche applications such as dirt bikes. Too bad Honda will have them outlawed sooner or later...

I"ve been saying this for months (years) now. Want a taste of the future, try a new Ski-Doo E-TEC DI Two-stroke snowmobile. There is no longer any reason to vote four-stroke as the new DI two-strokes are lighter, stronger, use less fuel, cost less,.... The biggest challenge they face is public perception of two-strokes as being loud and smokey.

I see more ppl trying to get their 2strokes running at the track more than any other engine configuration, the V4 config coming in a close 2nd.

I never really caught on the 2smoker scene, they seem to be more trouble than they're worth to me.

Reliability.
I don't wanna change out pistons, worry about seizures, or have the common "get the damn thing started" blues.
I'm too old to even begin to worry about gettin pitched to the moon over an engine seizure.
Do I believe that there is misinformation out there? Sure I do. But I need to be convinced of the things I wrote above that they didn't even touch on in the article.
I hope it does come around... i hope it blows up and we can go around happy as breast feeding baby in Hooters... but I'm not sure that its meant to be.

My candle burns at both ends;
It will not last the night;
But ah, my foes, and oh, my friends--
It gives a lovely light!

Clean two stokes have my vote

Furious Styles- reliability? I had 10,000 miles on my polaris indy sport 340 when I sold, stock piston and rings. It ran awesome and I rode it WFO all the time. With porting that is not too radical you can get a lot of time out of a 2 stroke. Have you ever changed out a 2 stroke piston?? easier than butter on a warm muffin.

Is anyone here familiar with MacDizzy's Two Stroke Technology Exchange - TRX - YFS - YFZ - Glamis Sand Dunes The message board on his site has some of the best two-stroke info on the web, very knowledgeable and talented members. He now charges to be on the forum and it has gone down hill over the last few years.

The guy that runs the site, Rick Kirmil talked about a "single stroke" engine he was developing. Has anyone else heard of a "single stroke?

I love two stroke, but its gotta be Fuel Injection, if not then its the same O shiet.

I think that two strokes like to be ridden at 90%.... 110% results in all the calamity that is an overworked engine.

Once upon a time, over 10 years ago, I was fortunate enough to have two "legally" licensed Aprilia RS250's. Both bikes were a ton of fun, especially after I found out about drilling holes in the air box and a couple of easy tweaks that released more power. They were so light and easy to flick from side to side that they seemed more like a moped than a GP replica. I actually had a police officer stop me for "leaning too much" into a slow speed corner. He was concerned about my safety!

I did have a "Duh!" moment once on the RS250 though. I decided to do a stoppie (had never done one before). So I raced up to the left turn lane at an intersection (light was red), hit the front brake, and did a perfect 45 degree stoppie first try. My mistake was fully releasing the front brake. The bike rotated back down, the rear wheel hit, suspension compressed, and launched me back up in the air a couple of feet. Wasn't expecting that. Luckily, I landed upright with both feet spread out on either side of the bike. The driver stopped in the lane next to me must have thought me an idiot...and I was.
