Radical SR4 Clubsport

Introduction

In 1997 Radical launched it's first sports racer, the 1100 Clubsport, it was an instant hit. Dramatic styling, high-revving engine, sequential gearbox, high standards of safety, good value for money and immense fun to drive. A difficult act to follow, but that's the task of the all new Radical SR4 Clubsport.

The SR4 is the same size as the Clubsport it replaces, but that when the similarity ends. The styling could not be more 'radical'. The aggressive high downforce front with top-mounted cooling ducts was inspired by the Le Mans-winning Bentley. Low, swooping sidepods and ultra-low rear profile is reminiscent of the all-conquering Audi, while the triangular air intake, carbon aero screen, headlights and deep front splitter are all very Radical SR3. Even the twin exhaust pipe was inspired by the Ducati 999.

The chassis is all-new too, taking many of its leads from the Radical SR3 with its wider foot box, which allows room for two adults, higher side rails with crash bar for greater safety and angled roll-over bar with integral rear brace for low aerodynamic drag.

The Clubsport's unique 'Nik' rising-rate suspension and anti-roll system is retained at the front while the rear now boasts the 'Nik' system developed for the Prosport car.

The SR4 is fitted with the latest 1200 Powertec Kawasaki motor and six-speed gearbox (a range of Powertec Suzuki engines can be fitted for non-championship use). Chain drive is retained for it's efficiency and minimal weight, but this system comes with a new easily adjustable mechanism. Drive is via a Quaife limited slip differential but with an integral Radical-designed reverse gear system, which eliminates the need for the electrical reverse gear of the Clubsport.

Four-pot racing calipers are standard at the front and rear along with four-bolt six and eight inch wide cast aluminium wheels. Optional centre-lock ultra-lightweight three-piece wheels and hubs are also available.

Like the SR3, the cockpit features a moulded driver and passenger seat, carbon dash surround and a Radical instrument panel.

So, is the SR4 Clubsport a worthy replacement to the 1100 Clubsport 'We think so'.

Inspired styling, proven engineering, two seats, guaranteed driving fun and comprehensively priced.

And what of the future? A 1000cc lightweight version for the US, road legal option for the UK, big Powertec Suzuki engines and rolling chassis self-assembly kits are all planned
