i have a few questions on these two bikes. i am currently rideing a 02 yz 250f, its been a good bike, i like the smooth power and its pretty much what i learned to ride on but it just feels heavy to me. i ride woods about 60% of the time and light motocross about 40% of the time and im thinking about switching to a 2 stroke. i was actually going to buy a 200mxc before i bought my 250f, they were both at the same dealer, i couldnt decide on which one to get but my friend who was with me said the 4 stroke would be easier to learn on so that is what i bought. now im starting to wonder if the 200mxc or 200mx would be good for me now. i would like something light weight, have good low end torque and smooth power. what is the power like on these two bikes? is the power harsh? i dont want somthing i cant control that is why i would like to have smooth power, i guess i could use a flyweel weight if i had to. i read somewhere that the 380exc has smooth power but that would probably be to big for me. what is the difference between the 200sx and 200mxc anyway?
