The Boss Jr. looks as good as it performs! This beginner youth kart is packed with outstanding touches. Fine workmanship and attention to detail show through in every area, like CDI ignition, front and rear hydraulic disk brakes, headlights, tail lights, rear view mirror and even a 3-speed semi-automatic transmission with reverse! Padded dual seating accomodates two children up to approximately 5 feet tall so your kids can bring a friend along for the ride. Finger tip controled driver's seat adjusts from 30.5 to 32 inch distance to pedals so each driver can get just the right fit. To reduce heat and maximize horsepower on this model, Lianmei has incorporated a larger engine head on a durable and proven 107cc engine case resulting in a more reliable design with a combined output of approximately 125cc and enough power to propell the kart to speeds of up to 26 mph.
