HJC RPHA 1

The original HJC RPHA 1 is a full-face racing helmet. HJC’s European documentation identifies ECE 22.06 and FIM FRHPhe-01 homologation.

Who should consider it

Riders investigating the original European RPHA 1 for a sport or track shortlist.

Features and trade-offs

HJC describes a PIM shell with carbon and carbon-glass reinforcement, a removable interior and double D-ring fastening.

The original model’s homologation should not be substituted for an event’s current requirement. RPHA 1 V2 and Carbon versions need their own checks.

What to check at a fitting

Assess the view in a tucked position and practise the D-ring closure. Request the exact version, size and homologation label before paying for track equipment.

Start with the manufacturer’s size chart and keep the helmet on long enough to identify pressure points. Follow the model’s fitting instructions and repeat the retention checks after any approved adjustment. Record the size and padding configuration that works for you.

Use the helmet fit checklist before comparing accessories.

Two alternatives to try

• Shoei X-SPR Pro (EU). Riders building a sport or track shortlist who want to examine the original European X-SPR Pro and its CWR-F2R visor system.
• Arai RX-7V Evo (EU). European riders considering the RX-7V EVO’s full-face layout and VAS visor system.

Compare these three helmets. Keep the version labels visible when considering models from different markets.
