HJC RPHA 91 Helmet

Premium Modular Engineering for All-Day Touring

The HJC RPHA 91 is a sophisticated modular touring helmet engineered to provide exceptional comfort and performance over long distances. Utilising the new PIM EVO shell construction, this helmet combines carbon-aramid, glass fibre, and natural linen fibres to achieve superior shock resistance while remaining lightweight. With its dual-homologated P&J chin bar and integrated sun shield, the RPHA 91 delivers a refined riding experience for all-season touring.

Key Features

• PIM EVO Shell: A hybrid blend of carbon-aramid, glass fibre, and organic materials for enhanced impact protection and weight reduction.
• P&J Dual Homologation: Features a secure locking mechanism to safely ride with the chin bar in the open position.
• Two-Way Pivot Chin Bar: Allows for a lower, more compact profile when open to significantly reduce wind noise and air drag.
• Adjustable Sun Shield: An anti-fog coated internal visor with a three-position depth adjustment to suit different facial morphologies.
• RPHA Perfect Fit Interior: Uses advanced anti-bacterial, moisture-wicking fabric with 3D contour cheek pads for a secure, plush feel.
• Automatic Shield System: The chin curtain retracts and the locking system hides when open to further streamline aerodynamics.
• Smart HJC Integration: Specifically designed to house the second-generation Smart HJC 50B or 21B Bluetooth® systems with optimal weight balance.
• Glasses Friendly: Dedicated grooves in the interior lining comfortably accommodate riders wearing spectacles or sunglasses.

Advanced Aerodynamics and Comfort

The RPHA 91 focuses on noise reduction and aerodynamic stability through its innovative chin bar mechanics. By utilising a two-way pivot, the helmet maintains a low centre of gravity even when open, preventing the "sail effect" common in modular designs. Inside, the interchangeable cheek pads across all shell sizes allow riders to customise the fit to their specific head shape, while the washable liner ensures long-term freshness for frequent travellers.
