The first step on the radical ladder;
the SR1 XXR is the perfect track weapon for rookie and novice drivers embarking on their motorsport journey.

Although entry level, the SR1 offers an outstanding package with unparalleled performance for money, that will get you on the grid in a professionally administered race series.

The SR1 XXR has been substantially revised with a new design, increased aerodynamics and improved durability with RPE's new Generation 5 1340cc racing spec engine.

Drivers of all ages and backgrounds have taken advantage of the detailed on-track tuition and support offered by Radical with the SR1 since the launch in 2012.

Such has been the rapid growth of this first step on to the Radical racing ladder, the SR1 was substantially revised in 2017 with dramatic new styling, improved aerodynamics and updated electronics, and again in 2023 with the XXR generation reinforcing that you can’t go faster and have more fun for less.

Core to the Radical DNA is the aerodynamic grip, nimbleness and balance. Known all around the world, by drivers of all abilities as a terrific car to drive – easy to pick up but hard to master.

Unlike road cars that have been modified for track use, the full Radical range has been designed for track use from factory.
The chassis is optimised for performance, focusing on aerodynamics, high downforce, and stability at high speeds. This ensures that the car provides maximum grip and agility during high-performance driving.

Beneath the skin of every Radical is a tubular spaceframe chassis that provides an excellent strength-to-weight ratio, enhancing the car's overall performance and safety. The design of the chassis helps reduce the overall mass of the vehicle, resulting in improved acceleration, braking, and cornering performance. Surrounding the chassis, the lightweight composite fibreglass bodywork is available in a choice of seven colours from factory. Combined with the spaceframe chassis, this provides unbeatable value for money for a pure track car that is easy to maintain and repair anywhere in the world.

Adjustable rear push rods and three-way dampers allow drivers a full range of control to setup the car ready for the track ahead.
An adjustable rear wing allows the driver to change the setup to suit the conditions, exploring the balance between straight-line speed and cornering performance.

With over 25 years of experience and almost 3,000 cars sold to date, every component on a Radical has been tested under extreme conditions to give customers the confidence they need to push lap after lap. New innovations, such as the optional cockpit safety structure, are designed to further protect the driver. FIA specification crash boxes and fuel cells along with full electronic fire extinguisher systems come as standard.

Choose from single or dual seat options to allow for driver coaching or entertaining passengers. Each car is also available with various seating position options including centre-seat, left or right-hand drive.
The dashboard features a customisable digital display to bring real-time information to the driver, and can be equipped with an optional onboard video system with GPS and race logging, including brake pressure and steering sensors.
