Crown Concepts is pleased to offer this 2021 Radical SR3 XX, chassis number 1336, finished in white over a black interior.
This SR3 XX is powered by Radical's 1340cc RPE-Suzuki four-cylinder engine and paired with a six-speed sequential paddle-shift gearbox with auto-blipper. In 1340cc specification, the SR3 XX is factory rated at 195 bhp, with published performance figures including a 3.3-second 0–60 mph time and a 141 mph top speed.
This example is especially notable for its recent drivetrain service. The engine and GDU were rebuilt on 02/16/2026, and the car currently shows 2.2 hours recorded since the fresh rebuild. Additional drivetrain details include a 3.235 gear set and spin-safe clutch.
Equipment includes a center-seat configuration, triple-adjustable dampers, air jack system, engine oil heater, radiator fan, fuel pump-out system, quiet exhaust, fuel injection, limited-slip differential, and Radical center-lock wheels. The car has been used for track days and racing, and its overall condition is reported as great.
Photos are available of the exterior, interior, engine bay, and underside, along with an engine start and running video.
This SR3 XX presents as a strong turnkey track or race car candidate, with the major value point being the freshly rebuilt engine and GDU with only 2.2 hours recorded since completion.
