Long live the two smoker! I saw a snowmobile do a 7 second 1/4 mile at Thompson dragway in N Oh a few years ago. I think it was a 700cc. It sounded AWESOME. There was another Kawi 2 stroke that sounded better, but I don't know the displacement. FAST, FAST, FAST.

That beach race vid was awesome!! Great to hear that big bore 2T!! I'd imagine that a 500 smoker would have an advantage on 450 4T; esp. in that deep sand. None the less, the rider always is the wild card. A fast sand specialist on a 450 would probably negate much of any advantage a 500 2T pilot may have. Just my $.02

you all forget 2-strokes make power every stroke, 4 strokes every other stroke. look at the old school 2 stroke GP bikes . 500cc=160+ hp EASY. hell even back in the early 70's they where making 120hp in frames w/ a hinge in the middle. :yikes:
you guys would cream your panties if you rode anything (2 or 4 wheels) with this engine in it. the only reason 2 strokes died is cause of politics and people being told lies. theres technology out there that could have 2 strokes running as clean if not cleaner than 4 strokes. simple as that.

little info i found on gp bikes of today. notice they have to almost double the CC's to get the same/a little better HP and they are heavier.

MotoGP, the premier class of GP motorcycle racing, has changed dramatically in recent years. From the mid-1970s until 2002 the top class of GP racing was restricted to four cylinders and 500 cc, regardless of whether the engine was a two-stroke or four-stroke. Consequently, all machines were two-strokes, due to the greater power output for a given engine capacity (produced up to 190 horsepower).


In 2002, rule changes permitted manufacturers to choose between running two-strokes engines (500 cc or less) or four-strokes (990 cc or less). The new four-stroke machinery proved to have too many advantages over their two-stroke rivals (up to 250 horsepower), and, as a result, by 2003 no two-stroke machines remained in the MotoGP field. The 125 cc and 250 cc classes still consist exclusively of two-stroke machines. For the 2007 season the capacity of the MotoGP machines has been reduced to 800cc in an attempt by the FIM to limit top speeds and improve safety. Early tests have shown that the 800cc machines do have a slightly slower top speed, but are capable of higher corner speeds than the larger 990cc machines were. back to top



Two-stroke versus four-stroke
The 500cc bikes of the late 1990s and early 2000s were brutal machines. Light, agile, and extremely hard to ride. These machines were brilliant race bikes and made for very entertaining and competitive racing. The FIM, however, decided that a change was needed to improve the quality of the sport. Two-stroke technology had reached a plateau, and the FIM wanted to ensure that Grand Prix racing did not become stagnant.

To ensure that there was continual technological evolution, the FIM decided to rewrite the regulations for 2002 and allow 990cc four strokes to compete with the 500cc two strokes. The results were spectacular. The 990cc configuration was immediately competitive and the bikes looked and sounded like the sport bikes available to consumers on the showroom floor. By 2003 there were no 500cc two stroke bikes racing in the MotoGP championship.

What the? How many strokes? You best study up on your 2s and 4s before you go sayin who creams their panties and who don't.

opppss my bad. im tired man. :p

- Two-stroke engines fire once every revolution (four-stroke engines fire once every other revolution). This gives two-stroke engines a significant power boost.
- Two-stroke engines have the potential for about twice the power in the same size because there are twice as many power strokes per revolution.

same difference in my book. lol either way they make more HP for the CC's of the engine. PERIOD :nener:

I'm pretty sure you edited this, because you thought you were wrong, but now you're wrong.
For every 360 degrees of crank travel (one revolution) there are 2 strokes, the engine only fires when the pistons near the top not the bottom. That means it fires every other stroke.

Actually, I think you were right the first time and I was wrong. Funny how it don't even matter now.

Id kill for an 02 YZR500, such a sick bike

that v4 is specifically for snowmobiles it would never fit in a motorcycle properly maybe a quad or honda civic but not a motorcycle.

boy, you's on crack, ANYTHING CAN FIT ANYWHERE if you want it too, im sure they said that about chevy V8s and you now have the boss hoss, gas turbines, the Y2K bike. Then you have the guy who built the Tularis (800cc polaris 2-t)

buy me the road race V4 on that page, ill prove you wrong and make it fit :cool:

yeah, I'm sure they're all modded. Because they'd have to be :coocoo:

and, if you listen, he's beating a lot of two strokes as well.

Huh... I can't hear any other smokers, but I'm not saying that there isn't. I just can't hear them with my speaker set up. All I know is, that guy was making everyone else look slooowwwww...

There were other 2-strokes in the race, but they were faint under the sound of the 4-strokes...
