I've held the steel frame from my EXC in one hand and the alloy frame from a CR125 in the other. No contest, the alloy frame is much heavier. Alloy is used for motorcycle frames not because it's light but because it's manufacture doesn't require human labour. Can't catagorically say for sure which is more rigid but I bet the chromoly is.
Weight is not a strong factor for most buyers when choosing a bike, so it's not a serious design consideration. It should be.
Go soothingly on the grease mud, as there lurks the skid demon
