My 9 1/2 yr old is on a 1992 KX 60. He looks big on the bike (actually the bike looks short in wheelbase), but he is not ready for a 2-stroke 85. He is actually faster around the track on his '01 XR 70, but he beats the hell out of the suspension jumping. He is not using all of the power The KX has, and the hit is a little too much for him to stay on the pipe. I want to get him a newer bike. What are the improvements on the 2002-2004 KX's over the '92? What is the best way to improve the bottom end power, or take the "hit" down a little? How does the KTM SX 65 compare to the KX in power characteristics and maintenance requirements? Any advice would be appreciated.
Thank you
