Designed by renowned race car engineer Mike Pilbeam, the Radical SR3 is the marque’s most successful model, originally developed for international competition in the FIA C3 class. This 2008 example has been modified for enhanced performance and drivability, featuring a stroked and bored engine, a lightened chassis, and a centrally repositioned driving seat for improved weight distribution. Acquired by the current seller in Pennsylvania from a Florida-based track day enthusiast, it has since competed in approximately 15 hill climb events and several track days. Benefiting from an engine rebuild by Rilltech Racing in 2024, the car has approximately five hours of runtime since and is now being offered for auction out of Pennsylvania.
This example presents a red, white, and blue livery and features a full-width front splitter, dual roll hoops, fender-mounted rearview mirrors, side air intakes, a center-mounted air intake, and a prominent rear wing. Additional exterior equipment includes quick-release body panels, a center-exit exhaust, and front and rear tow hooks. The seller notes that both the front splitter and rear diffuser have been replaced with lightweight carbon fiber components. Additionally, the car rides on red-finished multi-spoke center-lock wheels mounted with Avon racing slicks. Detailed images are provided in the gallery.
The cockpit has been reconfigured for competition use with a single central-mounted racing seat equipped with a six-point harness. A quick-release three-spoke steering wheel fronts a digital dashboard with integrated data logging and engine monitoring capabilities. Additional features include a fire suppression system, master kill switch, and a toggle switch panel. The stripped cockpit is finished with exposed carbon fiber surfaces.
The SR3 is equipped with a Suzuki Hayabusa-based inline-four engine paired with a 6-speed sequential manual transmission. According to the seller, the engine was most recently rebuilt by Rilltech Racing in preparation for the 2024 racing season and features a stroked and bored configuration for increased power output.
This SR3 is offered with a bill of sale.

I will get some measurments later today
My brother is 6'1 and you can see from the video he has plenty of head spacing under the roll bar.
Can you give me a couple of measurements. The height from the bottom of the seat to the top of the roll bar, and the distance from the back of the seat to the pedals. I’m tall and have trouble with many cars. Thank you.
