My 12yo son has a 04 KX-85, my 13yo son has a 02 kx-100. The 12yo races mx locally and is on the verge of getting to tall for the 85, but fits the 100 fairly well. He is not ready to move up to the "supermini" class which is the required class for the 100 in AMA races. Is there a "big wheel" kit available for the 85s or what can we do less putting the 85 motor in a 100 chasis? TIA

The Kx85 and the Kx100 have the same engine believe it or not its just a bigger frame but yeah i've seen people on youtube with big wheel kits but i think u should take him to the next level even if he wont win just to get him ready
