For the 2025 model year, Radical Motorsport is raising the bar with significant upgrades to its popular SR3 XXR and SR10 XXR models. With a focus on safety, reliability, performance, and personalization, the updates offer existing and new owners the chance to enhance their vehicles for the upcoming season, with many features available as retrofits for older models. These MY25 changes are designed to ensure that Radical’s race cars continue to set the standard on the track.
A New Level of Safety
Safety takes center stage with the introduction of an all-new carbon single seat for both the SR3 XXR and SR10 XXR. Developed in-house by Radical’s research and development team, the seat responds to feedback from customers, particularly in the USA, and features an integrated wrap-around headrest for enhanced protection. Made from pre-impregnated carbon fiber, the seat is lighter and stronger than the previous GRP version, and it is available in left-hand, right-hand, and center-hand drive configurations.
For drivers who prefer the twin seat option, safety has also been improved. Kevlar inserts and stronger seat mounts have been added, ensuring that both driver and passenger are secure during high-speed track experiences. To further enhance personalization, Radical now offers harnesses in four color choices, allowing drivers to match their interior setup to their preferences.
Enhanced Reliability for Maximum Track Time
Radical has applied customer feedback to improve the reliability of its race cars. One key upgrade for the SR10 XXR is a redesigned bellhousing, which has been strengthened using simulated stress tests to reduce the likelihood of cracking. This improvement boosts durability and helps drivers stay on track for longer, with fewer mechanical concerns.
The carbon fiber front splitter has also been re-engineered using aerospace-grade epoxy resin and new production techniques. This results in a more durable and better-fitting component, ensuring that the SR10 XXR can handle the rigors of competitive racing without compromising performance.
Performance Gains That Shave Milliseconds
When it comes to race cars, every millisecond counts, and Radical’s engineering team has found new ways to improve the SR10 XXR’s performance. By altering the radius of the sidepods, the aerodynamics have been fine-tuned to shift 2.5% of the car’s balance toward the front axle. This results in a substantial 11.5% increase in frontal load at high speeds, reducing understeer and improving cornering performance.
The steering rack ratio has also been adjusted from 1:43:1 to 1:71:1, requiring less driver effort to steer. This reduces fatigue during long races and increases both comfort and control. Additionally, a new lightweight flywheel and clutch enhance the SR10 XXR’s blip response, providing smoother downshifts, reducing rear axle shift-locking, and shortening brake zone times.
Personalization: Stand Out in the Paddock
Radical Motorsport offers extensive personalization options for the 2025 model year, allowing owners to make their race cars truly unique. The latest SR10 XXR was unveiled in a bespoke Daytona Green hue, showcasing the customization capabilities available. Along with custom bodywork colors, lightweight Braid wheels can be painted to complement the car’s exterior. Inside, customers can choose from a variety of color harnesses to match their preferences.
For those looking to make an even bigger statement, Radical offers custom-designed liveries that can be applied at the factory. Each personalized vehicle undergoes a quality inspection and professional photoshoot before being shipped to its final destination via Radical’s global dealer network.
Ready for 2025 and Beyond
The 2025 updates for the SR3 XXR and SR10 XXR reinforce Radical’s reputation for producing world-class race cars. With upgrades that enhance safety, reliability, and performance, along with extensive personalization options, these vehicles are designed to meet the needs of competitive drivers worldwide. The availability of these enhancements ahead of the 2025 season, combined with 2024 pricing, makes this the perfect time for racers to secure their track weapon of choice.
Whether you’re an existing owner looking to retrofit your current vehicle or a new customer preparing for the 2025 season, Radical’s SR3 XXR and SR10 XXR offer unparalleled performance, safety, and customization options, ensuring that you can race with confidence and style.
