Honest opinion (2 vs. 4)...

Why do it............

They would all be going BRAAAAAAAAAAAAAP.

Yes, I do... maybe even more of them would be out if they were all on 2 strokes? Maybe all of them would be out...

Hey dude, I hear ya.
I do think the likelihood for injury is greater with the current 4Ts,
The whole sport has been neg impacted by 4's.

I dont know.... seems to me that the engine desgn with the more pronounced engine braking of a 4 stroke would lend itself to more guys going over the front end when they chop the throttle. We should really be asking Jimmy Button, Ernesto Fonseca, Chad Reed this question since they have all ridden both engine types at the national level.

Didn't the 500 two strokes get eliminated from Supercross partly because of safety concerns? Sure seems like ALOT of top guys do not make a transition to the 450's without injury after injury. Must make it a tough sell to advertisers outside the industry to consider putting their advertising dollars in the sport.

It's called progression. Just about every sport gets faster or harder as time goes by. Athletes push the edge more and more as things evolve. I'd be willing to bet that if 2-strokes were still being raced they would be making more power with them than they did 10 years ago, allowing the riders to do more with them and probably crash just as much as the 4-strokes do.

If the east/west were riding 250cc 2 strokes and the sx class was riding 500 cc 2 strokes, probably so. Going back to 125's and 250's, probably not. They were getting 76 lightswitch hp out of a supposed YZ400/426F over a decade ago. Looks like the same setup Stewart is currently running.

I think you confused people by the way you wrote your question. I *think* I get what you're trying to say, but I also *think* that the way you wrote it, it comes across as the opposite of what you were trying to say.

This leads to a question I've had for some time now.

If I traveled back in time and killed my grandfather, then logic dictates that I cease to exist

If I ceased to exist, then how could I have traveled back in time to kill my grandfather?


Oh, and why the hell am I killing my grandfather?

I just don't get it sometimes, honestly WTF is the angst with 4 strokes? I race every weekend, practice every week so I look at it from a competitive view. They do make you faster without the work of a 2 stroke, that is the name of the game right, faster equals winning ? At 38 I still race to win not for 2nd or whatever. My mom came to watch me race last weekend and said after my first moto, "Well you still look good, you have the same style" I ride my CRF 450 just like I rode my Kx250 I ride the clutch in corners bangin the rev limiter floating the valves it doesn't feel any different to me just seems to "tractor" more. Now I have been off a bike for 8 yrs prior to getting this 450, maybe thats why I don't really feel a difference. I'm not a "PRO" but have had a really good AM career with a national win and afew AMA AM supercross podiums, looking back I felt like I was always on the edge of disaster I don't feel like that on the 4................

In many other motorsports technology eventually allows for a pace that becomes an apparent risk to driver safety. Eventually sanctioning bodies step in to slow the machines down. What we are seeing in Supercross/Motocross is nothing new to motorsports. It is not a 4-stroke vs. 2-stroke issue, it is an issue of engine power. Furthermore (as torco mentioned), riding techniques have also evolved the progression of the sport. Combining these two factors and the injury rates really shouldn't be a surprise to anyone.

Say tomorrow, NASCAR allowed engines that could reach 250mph on super speedways. It wouldn't take a rocket scientist to figure that there would be worse crashes and a likely increase in fatalities. On the flip side, imagine if the AMA mandated that the supercross series be run on supped up pit bikes. All four strokes have done is open up more doors as to how fast elite athletes can go on a motorcycle. And finally, placing all the blame on the machines is not right either. If you ask a majority of pros if they think the bikes are too fast, they would probably disagree (and I would too, they seem to have adapted quite well). The problem is that the human body is still the same ol' bag of bones.

K-dubs opening ceremony transfers really go to show what small percentage of a 450's power it takes to go around a supercross track.

My solution?

This isn't actually a Time Paradox. You see, you had to exist in order to go back and CHANGE time...therefore you are revising history and existence; yet, you existed and these events happened...theoretically, that is.

And, yes, why the hell would you do this?
