Radical makes some of the best, speediest, most mind-bending track cars out there, and come 2025, the good-old SR3 XXR and SR10 XXR have seen some quality-of-life updates. Mainly, you will notice significant upgrades when it comes to the safety, reliability, performance, and even some new personalisation options for these track monsters. Best of all, most of these updates are designed to be easily retrofitted onto the pre-2025 SR3 XXRs and SR10 XXRs. So, if you have just bought one, you can still enjoy these upgrades without having to buy entirely new cars. A handful of these changes might still be compatible with the older SR3 and SR10 models, too.
Nonetheless, if you’ve been holding out on spec’ing your dream Radical, they’re offering these 2025 model year SR3 XXRs and SR10 XXRs at 2024 pricing. So, now is probably the best time to look at preparing early for the next season of hardcore racing. With that said, let’s start taking a peek at all the 2025 model year updates to the Radical SR3 XXR and SR10 XXR, starting with the most important bit – protecting that noggin of yours. Though it’s mostly designed to meet the needs of the US market, you can now slip yourself into Radical’s all-new, in-house carbon fibre bucket seats, with a bespoke design that makes them even stronger and lighter.
Now Made Even Safer, Yet Becomes Even More Reliable
So, about those carbon fibre bucket seats – they’re built with pre-impregnated carbon fibre. It’s basically lighter and stronger than the previous GRP seat design. On top of that, it also features a wrap-around headrest for added protection. Regardless, you can fit these new seats either in left-hand drive, right-hand drive, or even centre-hand drive configurations. Additionally, if your friends or significant other wants a ride-along, or if you’re using your new Radical for coaching and passenger rides, you can spec it with a twin-seat setup. Elsewhere, occupant safety has been improved too, with stronger seat mounts and brackets, Kevlar inserts, and new harnesses.
All in all, those seats will offer you better safety and comfort, while those brackets and mounts might even increase your Radical’s structural integrity. Another noteworthy upgrade that you’ll notice in these 2025 SR3 XXR and SR10 XXR model year updates is better reliability! Radical has learned a lot from customer feedback and stress testing the older cars. With a new and freshly redesigned bell housing, there’s a reduced risk of cracking and better durability, particularly on the SR10 XXR. Besides that, there’s an improved carbon fibre front splitter, reverse-engineered using aerospace-grade epoxy resin, further improving your aerodynamics and fitment.
Edgier And Sharper Performance To Tackle The Track
Of course, the most exciting bits are the tiny improvements Radical has made to sharpen the performance of these new 2025 SR3 XXR and SR10 XXR model-year cars. For instance, you folks who are eyeing an SR10 XXR will get modified side pods, which have shifted the balance by 2.5% towards the front axle. As such, at higher speeds of 160mph or thereabouts, that should translate to 11.5% more frontal load. TL;DR, that should help reduce understeer and improve its cornering performance. The steering rack ratio has been changed from 1:43:1 to 1:71:1, as well. This should make high-speed turning on track a bit easier and less fatiguing for you.
Moreover, Radical has made some upgrades to the flywheel and clutch, allowing you to enjoy faster throttle response and smoother downshifts. In addition, these should also help with any reduction in rear axle shift-locking and shortening your braking zone duration. Altogether, the 2025 upgrades here should help you cut down on your lap times. I also mentioned that they’ve added more personalisation options. These mainly include new colour options and liveries that you can choose from, as well as new lightweight wheels, and more. It may not sound like much, but these small (but meaningful) updates should make your Radical that tiny bit better now.
