2025 Sparco helmets: Stealth RF, RF Carbon and Flux RJ
Sparco’s 2025 helmet range brings FIA 8859-2024 approval to three distinct choices: the full-face Stealth RF and Stealth RF Carbon, and the open-face Flux RJ. The shell format and communication equipment are the first things to settle before choosing a finish. This is our January 2025 launch overview. The showroom photograph records an earlier Sparco RJ; the linked product cards show the models discussed here.
How the three helmets differ
| Model | Shell and format | Useful distinction |
|---|---|---|
| Stealth RF | Full-face fibreglass, reinforced with a carbon-fibre liner | Black or white shell; red or black interior |
| Stealth RF Carbon | Full-face carbon fibre | Exposed carbon finish; prepared for optional drink and intercom systems |
| Flux RJ | Open-face fibreglass, reinforced with a carbon-fibre liner | Open-face layout; an intercom is an optional addition |
All three were listed in Sparco’s 2025 catalogue with FIA 8859-2024 approval and fitted HANS anchors. That approval does not decide whether an open-face helmet is permitted in your particular car or event. Match the helmet label and format to the organiser’s current requirements.

The Stealth RF and RF Carbon
Both Stealth models use two shell sizes and ventilated EPS liners. Their removable, washable interiors are offered in red or black, which is useful when you want to clean the lining between meetings. The visor has three positions and a central locking mechanism.
The RF Carbon uses a carbon shell where the RF uses reinforced fibreglass. Choose between those constructions after trying the fit; carbon construction alone cannot tell you how a helmet will feel on your head. Neither “intercom ready” nor “drink-system ready” means those accessories are supplied.
Garreth’s top tip: bring your balaclava and head restraint when you try a helmet, so you can check the whole combination before ordering.
Flux RJ and Flux RJ-i are different specifications
The Flux RJ offers the open-face alternative, with a peak, two shell sizes and removable interior padding. Sparco’s catalogue lists matt black and gloss white shells and red or black lining choices. A sun visor is optional.
The plain Flux RJ needs a separately specified communication system. The Flux RJ-i is the version with an integrated intercom and female Nexus connection. Check the amplifier match as well as the plug before choosing either route.
Approval, sizing and related reading
Sparco’s catalogue size bands run XS 53–54cm, S 55–56cm, M 57–58cm, M+ 59cm, L 60cm, XL 61cm and XXL 62cm for these models. Circumference narrows the choice, but the fitting check still matters. Do not select a loose helmet to make it feel comfortable.

Questions before you order
Is an intercom supplied with the Flux RJ?
The plain Flux RJ is supplied without an integrated intercom; the Flux RJ-i has one, with amplifier compatibility still to be checked.
Can I use the Flux RJ in an open-cockpit car?
Check your event’s required helmet format, because FIA approval does not make an open-face helmet suitable for every application.
Are the photographs all of the new 2025 models?
