"The ATK 125 arrived 3 business days after ordering in a steel reinforced crate. A weld had broke on the crate during shipping, but it didn't damage the kart. The assembly instructions are somewhat poor but were still able to unpack the parts and put it together in about 3 hours, including front wheel alignment and some minor grinding to correct misaligned seat bolt holes.
My kids (8 and 10yrs) have driven the kart about 5 hours so far and absolutely love it. It is a bit big for the 8 year old, but just about right for the 10 year old. The kart has plenty of power for a this size class."
