I agree the 400 is faster handle better and is a fun to ride, but what if you ride in the woods a lot and the trails are real narrow and you have to do a alot of backing then the 300 is better and still rides and handles really good. Dont get me wrong i would have traded my 300 when the 400 came out except it hasn't got reverse and the poeple i know with 400s always have trouble in the tight trails we ride, but they can always catch up on open roads. I guess for where i ride they are about even.
