yep, 2 strokes may come back. evenrude has the new direct injection 2 stroke that burns cleaner than a 4 stroke outboard. and honda toyed with this idea-

And I also read where some still say the KX and CR 500R's arent the king of the hill... lol... please go ride one, but be carefull!

I dont know about 2 strokes revving higher, my dale redlines at 11,800 rpm

 

thats true my 03 dale had a x440s/speed map and reved better than my banshee. and banshee had alot more horsepower but the dale sure got up out the hole alot better not spinning everywhere. and i also agree on the sand if i was building a hillshooter i would drop in a banshee motor with 10 mill crank and some cheetah cylinders in a yfz450 chassis and drag pipes and not to many would touch me in the sand but for a perfect all around duner i enjoy my yfz450 alot more, and i dont have to go back for fuel near as often as when i had my banshee longer rides = more fun for me. they all have there purpose and i hope to one day get my banshee powered yfz450 duner finished cause i know i will have fun on that to, and turn a few heads as well.

 

although not quite double the cc's. The 450s from factory come pretty well juiced. The 2-stroke could have alot more refinement done . If equal technology and same caliber of materials went into both the you would need at least a 500cc thumper to beat the 350 2pinger.

 

I had a CR 500 and even before the re-jet , air kit, pipe, and reeds. It would undoubtedly walk all over my buddies 450 four stroker- hands down......

 

I still could walk a cr500 till i topped out, then it would slowly catchup and pass me

 

Hmm... what do you have? (Because you wouldnt be foolish enough to think anything in your sig would)

 

i think hes talking about the cannondale and in the dirt it would hook up and get it off the line i know i have had both, as soon as the 500 gets rolling its bye bye cannondale. the dale hooks up better than any thing i have ever rode.

 

i outran an r6 until about 55-60 so i wouldnt get too big for your britches

 

It is sad to say but the day of main stream 2-stroke production is quickly coming to an end for many reasons.
1. New epa regs. make it nearly imposible for any 2-stroke engine in a motercycle or atv even with something like direct injection to pass the new regs. for much longer. There will a few bikes designated as "competition bikes" that will not have to meet as tight of regs. that will be 2-strokes for a few more years but they will also end
2. For all the companies to find and make new tech. to meet all the new regs. millions of dollors in R&D will have to be spent, that is money that could and probbaly be spent on furthuring the tech in 4-strokes, so why would manufactures spend money on something that will end anyways (2-strokes) when they could spend their money on making EFI and lighter materials for 4-strokes that is going to be the future of all power sports.
The fact stands that a 2-stroke makes as much emissions as about 12 modern cars so of course someone is giong to get pissed at that.
Here is what the epa says: the rules "encourage manufacturers of these vehicles to switch from two-stroke engines to cleaner four-stroke engines, beginning in 2006" for trail machines.
Don't think that in any way am I for the extinction of 2-strokes but the production of 2-stroke motercycles and atvs are going to end within the next 5 to mabey 10 years but I dought it will last that long.
