The single most intimidating / hardest to ride (fast) bike I have ever ridden was my brothers worked over CR500.

That thing still gives me cold sweats.

2010 might be the last year America gets any actually.

Maybe... But then people were winning races with them LOOOOOOOOOOOOOOOONG before anyone complained about environmental issues. Plus I know so many locals who'd rather ride the 4s than the wild and crazy powerband of the 2s. So I say "no" to your theory.

I think that is the reason people who like them, like them so much. The light switch fast powerband, the seemingly unlimited ability to rev, and that angry hornets nest buzz they make. They definately aren't for everyone. IMO just about anybody can jump on a thumper and be comfortable. Not so much on a 'smoker.

Ring dings. They're more like rodeo sex.

Great... But history and the change of motors was already being made.

The EPA was the big killer of 2 strokes, and is the major reason they're not being marketed. the europeans have some that are euro tier 2 compliant, maybe tier 3, I havent looked in awhile, but they're fuel injected, oil injected and pretty creative little fuckers. for the US market, its just not worth the hassle/money for the manufacturers to invest in the engineering to make them crackpot california compliant.

True true true.
Bimota built the V-due, a direct injection 2s that would have met (and did) epa and carb regs. it just bankrupted the company.....

as epa regs dissuaded the japanese co's and turned them away from 2s to 4s for ease of compliance, it forced them to look to 4s for racing also as research (race on Sunday, sell on Monday) dollars are always scarce...........

Its sad that 2 strokes cost so much to develop but honestly, I enjoyed riding an RD250 for awhile, they ARE indeed fun little machines, and simple to work on, but thats about all really. once you get into the technical details of keeping them running dependably, which I might add is hard if you're like me and like to run 2 strokes hard all the time, they lose their appeal.

Depends...I used to endurance race (12 and 24 hr races) a Gt750 Suzi; and that thing used to take abuse that brought most bikes to their knees....and we won or placed A LOT.....we raced one whole season on one engine...one crank, one set of jugs......

BobTheBiker · 02-22-2010, 11:48 PM

obviously there ARE exceptions, but I'm talking generally in terms of dirtbikes, not necessarily 3 cylinder water cooled bikes.
