Using a cutaway chassis cab, the Busette was fitted with a purpose-built school bus body, allowing for expanded seating capacity, with a rated seating capacity of 24. The use of a purpose-built body allowed for the fitment of school bus windows and a rear emergency exit. To keep weight down, Wayne designed the Busette with 63″ of headroom (approximately 10″ lower than a full-size school bus roofline), which limited standing room for older students and adults. Initially, curbside entry was provided through a makeshift arrangement using the original-equipment van door. After the 1976 introduction of the Transette, a conventional bus door and stepwell became an option.
