The 2006 Radical SR3 1500, manufactured in the United States and currently located in Berkeley, California, is a unique track-focused vehicle. This silver and red-accented machine, featuring fiberglass bodywork mounted on a steel spaceframe, was acquired by its current owner in 2012 for use at track days. Key to its performance prowess are its Suzuki Hayabusa-based 1500cc inline-four engine, linked to a six-speed sequential gearbox and a Quaife limited-slip differential. Standing out as an intriguing choice for racing enthusiasts.
