Sidewinder was produced by Marine Products & Equipment Corporation of St. Charles, Illinois. From a first glance, the early model Sidewinders look like direct copies of the Scrambler. They were built out of fiberglass. Exact company history is unknown, but it is believed Clay Radcliff from Sidewinder worked together with Hustler in later years. Radcliff would order custom color Hustlers, fit them with accessories then market as them as the Sidewinder. Such modifications included an exo frame design, longer axles, and bigger tires.
