Last weekend my friends son raced the 4-6yr(junior) class and beat a Cobra on a PW50! The rider is the big thing. I've seen a lot of kids on Cobras and Polinis that never could use all the bike. The Husky is not much different than last years KTM, and they were competitive. When my son was in the 50 class, he had a LEM in junior, and an Action in senior. I promised myself that if he ever rode the bike to its limits that I would buy him a Cobra. He never got one, but we learned alot and had fun.
