The HJC RPHA 1 helmet is developed using direct input from MotoGP riders and professional racing teams. Designed as a top-tier performance helmet, it focuses on aerodynamics, weight reduction, and high-speed stability.
This is a helmet built for riders who demand precision, control, and confidence at speed.
Premium Integrated Matrix Shell For Strength And Weight Balance
The RPHA 1 uses HJC’s premium integrated matrix shell construction, combining multiple materials to achieve an optimal balance between strength and weight.
This results in a lightweight helmet that still delivers strong impact resistance, helping reduce fatigue during long or aggressive riding sessions.
Aerodynamic Design For High-Speed Stability
The helmet’s aerodynamic profile has been refined through wind tunnel testing and real-world racing feedback.
An integrated rear spoiler and streamlined shell shape help reduce drag and minimise turbulence, keeping the helmet stable under acceleration.
Advanced Ventilation System
The RPHA 1 features a multi-channel ventilation system designed to maximise airflow.
Air intake vents at the front and top direct fresh air through the helmet, while rear exhaust ports remove heat and moisture. This helps maintain comfort during intense riding conditions.
Race-Ready Visor System
The helmet includes a high-performance visor designed for clarity and durability.
It is compatible with tear-offs and anti-fog inserts, making it suitable for both track and road use. The quick-release mechanism allows fast and easy visor changes.
Emergency Quick Release System
The RPHA 1 is equipped with an emergency cheek pad release system.
This feature allows first responders to safely remove the helmet in case of an accident, adding an important layer of rider safety.
Secure Fit And Performance Interior
Inside, the helmet features a fully removable and washable liner made from moisture-wicking materials.
The interior is designed for a snug, race-focused fit that keeps the helmet stable during high-speed riding.
ECE 22.06 And FIM Homologation
The helmet meets ece 22.06 safety standards and is also fim homologated, meaning it is approved for use in professional racing environments.
This ensures it delivers a high level of protection for both track and road use.
Track-Focused Ergonomics
Every element of the RPHA 1 is designed around a racing posture.
From the visor angle to the internal padding, it is optimised for riders in a tucked position, making it ideal for sportbike use and track sessions.
