The HJC RPHA 1 is HJC's race helmet, with a carbon shell and FIM and ECE 22.06 homologation: 1,438 g and €750. It is a serious track tool for track days; for daily riding, the RPHA 12 or the RPHA 71 make more sense. Score: 9/10.
PIM shell with carbon and 1,438 g
The shell is the PIM laminate reinforced with carbon and carbon-glass hybrid fabric, tuned for shock absorption and low weight. On the scale it is 1,438 g (size M, Champion Helmets). Homologation is FIM FRHPhe-01 + ECE 22.06, so it is ready for competition.
Visor
The visor uses the Rapid Fire Shield Replacement System: it swaps without tools, ideal between sessions on track, and is prepared for tear-offs. The closure is a double-D ring.
Aerodynamics and ventilation
It is wind-tunnel tested in HJC's own lab, with a stabilising profile at speed and the Advanced Channeling Ventilation System. The interior is SilverCool, antibacterial, moisture-wicking and quick-drying, removable and with grooves for glasses. Noise sits around 100–102 dB: average to high, and expected on a track helmet.
Price: €750
The recommended price is €750, with a 5-year warranty and an emergency cheek-pad kit included. It is a track tool: for pure road use there are more comfortable and quieter options in the HJC range.
Pros and cons
Pros
- Homologation: FIM + ECE 22.06, ready to race.
- Rapid Fire visor: tool-less replacement, tear-off ready.
- Aerodynamics: wind-tunnel tested, stable at speed.
Cons
- Noise: 100–102 dB, average to high for the road.
- Use: €750, and on the road it loses its point: only track riders really get their money back.
Verdict
The RPHA 1 is the race helmet for riders who want an FIM-approved carbon-shell lid for €750, with tool-less visor swaps between sessions. If you ride track, it is a solid pick in the HJC range; for daily riding, the RPHA 12 or the RPHA 71 make more sense.
Score: 9/10
