SR3 Supersport

The Radical SR3 Supersport represents race-focused variant of SR3 lineup featuring hand-built RPE racing-specification Suzuki four-cylinder engines available in multiple configurations including carbureted Powertec Suzuki 1,300cc producing 205 horsepower, high-compression carbureted 1,500cc producing 252 horsepower, and special-order options including 1,400cc, 1,585cc, and turbocharged Hayabusa engines. The carbon-steel spaceframe chassis with polyester bodywork weighs less than 600 kg (1,300 lbs), enabling extraordinary performance with 225 horsepower at wheels achieving 0-60 mph acceleration in 3.1 seconds and top speed of 147 mph. Advanced aerodynamics generate up to 2g cornering acceleration at high speeds providing race car downforce levels.

The Supersport represents upgrade from Tracksport with standard and optional features focused on racing applications including higher-horsepower engine options, racing fuel cell, additional roll cage structure, fire extinguishers, lower ground clearance, and optional high-downforce package. Unlike street-focused sports cars, the SR3 Supersport designed specifically for track use delivering professional race car performance at significantly lower cost than purpose-built racing machines. The combination of extreme lightweight construction, powerful motorcycle-derived engines, sophisticated aerodynamics, and race-focused engineering makes the Radical SR3 Supersport compelling choice for serious track day enthusiasts and amateur racers seeking genuine racing performance without compromises for street usability or comfort.
