HJC’s limited-edition RPHA 1 V2 Carbon “Funky Diablo” replicates the neon carbon-fibre lid Fabio Quartararo wore at the 2025 Catalan Grand Prix — exposed carbon weave under green, yellow, orange, pink and blue graphics, a glow-in-the-dark Diablo on the crown, and a €999.90 price tag. It’s already sold out in Europe.

I will never own this helmet. I know this before I’ve finished the sentence. But I’ve now looked at the same six product photos four times, which is roughly the same amount of attention I’ve given my actual to-do list today.

What HJC actually released

The Funky Diablo is built on HJC’s RPHA 1 platform — an exposed carbon-fibre shell developed with Quartararo and designer Sylvain of Aero Diffusion, based on Quartararo’s “El Diablo” persona. The graphic package layers bright green, yellow, orange, pink and blue over visible carbon weave, with a Diablo character on the crown finished in a glow-in-the-dark coating that stays lit after dark.

Underneath the graphics it’s the same race-grade shell HJC sells across the RPHA 1 range: an HJ-35 visor rated for 99% UV protection with anti-scratch coating and a double-locking mechanism, a titanium double D-ring fastening system, and HJC’s Advanced Channeling Ventilation System running five intakes and four exhausts front to back. It carries ECE 22.06 approval alongside FIM Racing Homologation (FRHPhe-02) — the certification that actually matters if you’re taking it on a track day, not just a coffee run.

Why it’s worth knowing about even though you can’t buy one

A helmet that sells out at €999.90 in its home market before most riders even hear about it says something about where HJC’s positioned the RPHA 1 line — this isn’t a budget lid with a flashy sticker job, it’s a genuine race-homologated shell with a replica graphic that MotoGP fans were always going to fight over. If you’re after the RPHA 1 without the Diablo tax, HJC’s regular colourways are still in stock, and if it’s the glow-in-the-dark novelty you’re after, Sena’s flagship 60X intercom or Cardo’s Venture helmet are both worth a look for the kind of rider who actually cares what their comms setup looks like at 2am in a service station.
