HJC RPHA 31

The HJC RPHA 31 is an ECE 22.06 open-face motorcycle helmet with a long HJ-39 outer visor and an adjustable HJ-V12 internal sun shield. This collection combines complete helmets in solid colours with the correct HJ-39 replacement visors, DKS467 Pinlock inserts and HJ-V12 sun shield.

Its open-face format gives a broad field of view and convenient access around the face, while the long outer visor provides weather coverage. It does not have a fixed chin bar, so riders should understand that coverage differs from a full-face helmet before choosing it.

Who is the RPHA 31 for?

The RPHA 31 suits riders who prefer an open-face helmet but want a long main visor, an internal sun shield and road-focused ventilation. Its format can work well for urban journeys, commuting and touring where easy face access and a wide view matter.

PIM EVO shell and ventilation

HJC uses its PIM EVO composite shell for the RPHA 31, combining reinforcement materials including carbon-aramid, carbon, glass and natural fibres. The helmet has two intake vents and four exhaust outlets intended to move air from front to back.

The outer shell, visor deflector and visor holder are shaped to manage air resistance, turbulence and visor stability. Noise on the road will still vary with fit, speed, motorcycle screen height, riding position and wind direction. Suitable hearing protection remains important.

Fit, fastening and interior

Measure around the widest part of the head and use the size chart on the exact product page as a starting point. The crown should make even contact without sharp pressure at the forehead, temples or rear, and the cheek pads should hold the helmet stable without painful compression.

• Wear the helmet for several minutes before deciding on the fit.
• Fasten the one-touch micro buckle and confirm that the strap sits securely.
• Rotate the shell gently and check that it does not move independently of the head.
• Test glasses, earplugs and any planned communication speakers during the assessment.

HJC specifies removable, washable crown and cheek pads made with moisture-wicking, quick-drying fabric. The helmet is also prepared for SMART HJC 11B, 21B and 50B communication systems, which are separate accessories. Confirm cable and speaker routing before installing any system.

Our helmet sizing guide explains how to take the initial measurement, while the Moto Central head-shape video shows why circumference alone cannot confirm a suitable fit.

HJ-39 outer visor and HJ-V12 sun shield

The main HJ-39 visor is Pinlock prepared, anti-scratch coated and specified by HJC to provide 99% UV protection. The quick-release ratchet system allows the outer visor to be removed without tools. Clear and dark smoke replacements are currently represented in this collection.

The smaller HJ-V12 is the internal sun shield. HJC provides a dark smoke shield and allows its position to be adjusted through three steps. The outer HJ-39 and internal HJ-V12 perform different jobs and are not interchangeable.

DKS467 Pinlock fitment

Pinlock's official fitment information identifies DKS467 for the HJC RPHA 31 and HJ-39 visor. The collection includes clear Pinlock 120 XLT MaxVision and dark smoke Pinlock 120 MaxVision choices. A Pinlock insert helps manage condensation; it does not replace the impact and weather function of the outer visor.

• Remove the HJ-39 visor and support it on a clean, soft surface before installation.
• Check that the insert's silicone edge makes continuous contact with the inner visor surface.
• Handle the insert by its edges and avoid rubbing the moisture-absorbing face.
• Use lukewarm water and a soft cloth for cleaning, then allow it to air-dry.

HJC lists a DKS467 Pinlock 120 XLT insert among the complete helmet's box contents. Check the exact Moto Central product listing and packaging when buying, especially where stock or edition details may differ.

Cleaning and inspection

Clean the shell and visors with mild soap, lukewarm water and a soft cloth. Avoid fuel, solvents, abrasive compounds and household glass cleaners. Allow removed lining parts to air-dry fully before refitting them.

Before each ride, inspect the shell, EPS, strap, buckle, visor pivots and locking action. Replace a cracked or deeply scratched visor. A helmet that has received a significant impact should be assessed for replacement even if the outer finish looks undamaged.
