In 1964 the new continental line replaced the Dart cycle bikes, they offered a continental custom ( full suspension, H35 3.5hp), continental special (hardtail, front suspension, H25 2,5hp) , and the econo-cycle (2.5hp side tank, or in kit forum/roller) Lighting was optional and tail light was round and mounted to the fender, color was red that year, and they had steel wheels. the Gran Prix mags were introduced on the bikes for the 1965 as well as moving the tail light up to the rear top rail behind the seat An interesting thing was the Kart magazine cover photo with Playboy playmate June Cochran sitting on it the engine is a side exhaust H35, but the 1964 brochures and other photos all show rear exhaust with what was actually new at the time seven hole #30911 muffler
