Big Fury

Big Fury was a compact steel roller coaster at Six Flags Great Adventure, that operated from 1974 to 1977. It was a Pinfari Zyklon model Z64. The coaster was similar in design but smaller than Flying Dutchman, a Pinfari Z78 model, that operated at Dorney Park & Wildwater Kingdom, 50 miles (80 km) northwest of Great Adventure.

When Six Flags purchased the park in 1977, it was decided that a more exciting portable coaster would be an improvement. Big Fury was removed and sold to an unknown buyer and replaced by a Schwarzkopf Wildcat (54 m) called Wild Rider. Although Wild Rider had larger drops than a Zyklon and the two were painted different colors, this roller coaster is often confused with the Wildcat roller coaster that replaced it.
