First shown to the public at the 2002 Autosport International show in Birmingham, the Radical SR3 is one of the cheapest ways to go extremely fast. Originally aimed at the third of three divisions of the FIA sportscar championship, the SR3 can be used as track car or road car. An immediate hit, it was named 'Trackday car of the year' by Car Magazine.
The chassis is simple, but very efficient steel spaceframe, that offers plenty of rigidity at a very low weight. It is suspended by double wishbones all around, double damper units are available as an option. Braking is taken car of by vented discs, with cross drilled units available as an option. The fiberglass body adds next to nothing to 495 kg dry weight.
Installed in the spaceframe chassis, is a four cylinder motorcycle of various makes and sizes. The least powerful of the five engines available is the 130 bhp Kawasaki 1100 engine, with Suzuki's 1500 cc engine as range topper at 252 bhp. Mated to the engine is a sequential six speed gearbox, which allows lightning quick gearchanges.
Performance was better than expected and the SR3 started winning all across Europe in its first season. Road legal versions proved their worth in various road tests. On a damp Top Gear test track the SR3 beat the Pagani Zonda's best time, recorded on a dry track, by four seconds!
The featured SR3s are seen here on the Spa Franchorchamps track where it took part in the 500 mile, which was part of the 2004 RMU Classic weekend. Overall victory in that race was had by a similar SR3 1500. Detail shots were made on the 2004 Knockhill MotorFair of one of the IF Motorsport UK cars present.
After I read such praise about the SR3, I went out and bought one.252 horsepower and only half a ton to drag. Th SR# 1500 is the best, I outran a 2007 Z06 with it and it corners like a race car, plus it looks a bit like the old Ferrari 333SP to boot.
This is a really fast car! You must absolutely see the videos that you can download from the official site!
