Everything before 1976 was ABS plastic, then in '76 Attex built the Superchief and Spirit models (they were bright orange). In '77 they moved to a more yellow plastic or optional dark green and built the Superchief and Tomahawk models both with a Li'ltruck option offered.
For Busco at least, it's good to have a four-stroke for the trails and a two-stroke to blast around on the dunes with. As much as I hate to admit it, four strokes do better on the trails (did I really say that out loud?). With the long rides that the Carolina boys tend to take, you'd need an extra gas tank with a big two-stroke!
Stuck in the seventies- not in the swamp.
(6) Attex, a Hustler, a Super Swamp Fox, (2) Tricarts, (3) Tri-sports, a Sno-co trike, 3 Dunecycles, and a Starcraft! ...so far
