Moto-cross 4 stroke VS 2 stroke
Posted: Wed Aug 22, 2007 2:26 am
I haven't followed racing in at least a decade, but I used to be right into moto-x, etc...
Back in the day, all the hottest bikes were two stroke....my very own beloved RM80 is most certainly a two stroke. The sound or should I say buzz of that little engine always pushed me ahead of my friends who otherwise had four strokes.
Today I have friend who bought himself a Kawasaki (125/250 or similar) and it's 4 stroke. I laughed at him and called him a wussy and he explained that 4 stroke had come such a long way they now equalled 2 strokes in almost everyway. He then proofed his claim by hilighting most bikes in his category were indeed four stroke.
He proved his point but I am at a loss as to how this can be, having a basic understanding of the principles behind the two different types of engines, a 4 stroke out-performing a 2-stroke seems to almost defy logic. I searched Google.
It sounds as though, 2 strokes are slowly being replaced by the heavier, more complicated, albeit more efficient 4 strokes, but not nessecarily due to equalled performance. More like, regulations, environmental concerns, etc.
I had a similar argument with another friend a while back about his crotch rocket - he had told me it was 4 stroke and indeed it is. I was shocked and still am shocked.
Anyone know why and when these bikes started turning to 4 stroke technology?
