Depends on what size. If you’re talking about the “baby” kart, for 5-8 yr olds, then absolutely it will fit. The baby karts are the smallest and usually only run with the Comer C50/51 or the newer Honda GX50 motor. There is no minimum weight and the wheelbase is only 30-35″ and total length is around 50″ with nose attached. Maximum width is 42″ and usually narrower than that.
