ellandoh said:one more thing: assuming an even r&d budget id like to see the profit margin differences on a 2t vs 4t my guess is its about even or better for the 2t ..........all the extra close tolerance parts not to mention the titanium and other precious metal parts the 4 stroke is probably a bargain

steve125 said:Bike sales profit margins aren't the issue here. I agree they are probably close to the same 2 or 4 stroke. It's in the parts and accessories that the 4 stroke owner is getting boned. Like you said, all those close tolerance parts and precious metals. When they break or need servicing you pay 2x that of a 2 smoke. Not to mention the labor $ involved for those who are less skilled.
Spark rationing, so THATS what is at the bottom of this great 2-s vs. 4-s debate !!!!! I've always wondered .......YZ165 said:As soon as the two strokes are limited to one spark every two revolutions of the engine, I'll be happy to race a 250F against a 250 2T. Until then, the cc difference is necessary to create equality.
