The 1987 GT Mach One retains GT's classic racing frame design and combination of components from 1986. A good all around thrasher, but no less serious on the track when the gate drops. Pro Series™ Frame and Fork All racing frame and fork sets have a new look for '87. Hot new graphics compliment the new rear triangle area. Racing framesets are available in GT Blue, White, Black, and Chrome.
