MY SON HAS A 2003 XR100 WITH A CHM PIPE,AIRBOX MODS AND JETTED. IT RUNS GREAT FOR A 100 BUT HE WILL BE 13 IN SEPTEMBER AND HE IS NEEDING MORE POWER TO KEEP UP WITH ME. I WAS THINKING OF A 150F BUT I AM NOT SURE THIS WILL GIVE HIM MUCH MORE POWER. I WOULD LOVE TO BUY A 150R BUT THEY ARE RED STICKED HERE IN CALIFORNIA. IS THE 150F(AIR COOLED) A WAIST OF TIME? I WOULD PUT A PIPE AND JET ALSO. ANY SUGGESTIONS FOR NEXT SIZE UP? NEEDS TO BE GREEN STICKED!

we will answer you even if the message IS NOT IN CAPITAL LETTER ALL THE WAY

Rocketman,

What is your son's height and weight? What kind of riding do you guys do?

Oops sorry about the caps bad habbit! He's a kid! trails jumps a little bit of everything he is 110lbs 5'-5"

I only ask because if he is tall for his age then you could go for a 230 or 250. Maybe the 250X with a lowering link until he gets a little taller. If he is anything like me, once I turned 13 I got much stronger and taller.

The 250X I believe is green stickered. This bike would fit him for quite a while instead of getting a 150F which he may grow out of in a year or two.

A lot of people like the 230. Cheaper than a 250. Seems bullet-proof. Only thing is it is heavy, heavier than the 250X.

Then he would want my bike (250x) and i just got it! I did let him ride it, just a bit tall at this time and dad doesn't want to share that much yet! your probally right though. thank you for the input. Have you ridden a 100 and the 150f?

my brother-in-law used to have an 02 XR100R, i got my 04 CRF 150F before he traded, and it seemed to have more umph than the 100. Comparing them, the 150 accelerates quicker, lands jumps a helluva lot better, and the front disc brake worked awesome.
