Light Years, First dirt bikes were nothing more then stripped down road bikes, late 50's, up to early 70's the bikes were heavy, short travel suspension, and 99% of them were 2 stroke, they had to be on the pipe for power (high rev's). today you have high-tech, light, long travel, 4 strokes, power can be had all the way thru the RPM range.
