Especially when you compare to big diesel 18 wheelers when they get on the gas and there's huge clouds of black smoke pouring out on every single roadway across the US, everyday (and night) of the week. And it's not like dirtbikes are commuter vehicles on the road and running all the time everyday of the week. What does the average person do? Ride their dirtbike a few hours on the weekends and sometimes let them sit for weeks without riding? Yes there's people that do ride almost everyday, but I still think the majority of bike owners are more of a once a week(end) rider. I still can't see pollution output of dirtbikes amounting to anything significant.

this was a very good point :cool:DCMan said:I am still 2 stroke all the way & a green one at that! Most of the guys racing provincials up here in Ontario are on 2 strokes.
In relation to the pollution, some one once raised the point that you need to compare pollution/power. Don't forget 450's have almost twice the displacement of the 250 2-strokes. At equal displacement the 4-strokes may put out a bit less at the tailpipe but it is even negligible unless they run a catalytic. When comparing different displacements the 2-T should put out less. (Use synthetic oil mixed at 50 or 100:1)
