I just got my new rmz 250. I did'nt have time to completly break it in so I can't fully judge the total performance yet.What i can tell is it starts incredibly easy hot or cold, it's feels a lot lighter than my sons wr 250 f . It is incredibly sleek and easy to toss around the track. Not being used to four stroke braking the dual idle from neutral to in gear makes it much easier to ride after riding mastly two strokes.The bike seams to be everything they said it would be.It's so soooooooo sweet !!!!!!!!!!!!!!!!!!!!!!
