Specifications
The GFC SS31 was developed specifically for single-speed and TaG competition.
Constructed from high-grade 30mm chromoly tubing, the SS31 delivers excellent lateral feedback through long, high-speed corners while maintaining the flexibility and traction needed to put power down through tighter sections of the track.
Designed to perform across a wide range of engine and tire combinations, the SS31 provides a responsive, adaptable platform built for the demands of competitive single-speed karting.
