Rating : - Wish they had these when I was a kid
I bought this kart for my 8 year old 60 pound daredevil daughter. She loves control and speed. She races the boys on the street on a slalom course and everyone has fun. We have modified the kart slightly. The turning radius was large when we received it. It could barely U-turn on narrow streets. I cut the steering locks off with a hacksaw and file. It now turns with less than a 5 foot radius and is more responsive. Brakes needed adjustment for her small hands. The battery seems ok. She said she'll never get tired of his toy, even after having it for a month.
