Radical Generations: from precursors to SR3 XXR

Before SR3, Radical offered Clubsport and Prosport. The SR3, launched in 2001 and produced in 2002, notably introduces a Quaife differential instead of the final chain transmission. Its early variants include the Tracksport, Supersport and LM. Cars have often been modified: the chassis number and the actual equipment remain essential.

The Prosport 2002 brochure describes a Nik suspension and a 1300 with carburetors. The register indicates Prosport production started in 1999, with shared numbering until 2006 and a replacement chassis in 2009. For a passenger car, validate the suspension, the engine and the options: the parts may have been replaced.
