The HJC RPHA 31 is a premium open-face motorcycle helmet designed for riders who value a wide, open riding feel alongside modern materials and everyday convenience. Its streamlined shell, integrated sun shield and comfort-focused interior make it worth considering for urban rides, weekend journeys and touring routes.

Premium shell materials with a carefully shaped profile
HJC builds the RPHA 31 around its Premium Integrated Matrix (P.I.M.) Evo shell. The composite construction combines carbon-aramid fibre, carbon fibre, glass fibre, organic non-woven fabric and natural linen fibre. HJC describes this material mix as designed to support impact resistance while keeping the helmet comfortable and relatively light.
The aerodynamic outer shape is intended to reduce air resistance and improve stability. HJC also lists ECE 22.06 approval for the model; always check the approval label on the specific helmet supplied for your market.

Sun shield and visor features for changing light
The RPHA 31 includes an integrated, smoke-tinted sun shield with an anti-fog coating. Its lower-positioned control lets riders deploy it quickly, and the shield can be adjusted across three positions to suit individual preference.
The main HJ-39 visor is anti-scratch coated, provides 99% UV protection and is Pinlock-ready. A visor ratchet system is designed for quick, straightforward operation, while the removable visor deflector and visor holder help manage wind turbulence and reduce noise. A Pinlock 120 XLT anti-fog lens (DKS467) is listed as included by HJC Europe; check the contents for the exact colour or regional version you are buying.

Airflow and an interior made for regular use
HJC lists two intake vents and four exhaust vents to support front-to-back airflow. Inside, an antibacterial fabric is designed to wick away moisture and dry quickly. The crown liner and cheek pads are removable and washable, making it easier to keep the interior fresh over time.
Three-dimensional cheek pads shape the fit around the face, and dedicated grooves can make the helmet more accommodating for riders who wear glasses. Fit is personal, so try the helmet on and follow HJC’s sizing guidance before choosing a size.

Communication-ready for connected rides
The RPHA 31 is designed to accept HJC’s second-generation SMART HJC 11B, 21B and 50B Bluetooth communication systems. These units are sold separately, so check compatibility and package contents if communication is part of your setup.
The helmet uses a one-touch micro-buckle retention system. Before every ride, fasten and adjust the strap according to the instructions, and confirm the helmet sits securely without pressure points.
Is the HJC RPHA 31 right for you?
The RPHA 31 is worth a look if you prefer an open-face design and want a premium composite shell, an adjustable internal sun shield, a Pinlock-ready main visor and a washable comfort lining. As with any open-face helmet, it does not provide the same facial coverage as a full-face design, so consider your riding conditions and the level of coverage you prefer.
Specifications and included accessories can differ by finish or market. Confirm the size, colour, approval label and box contents for the exact version before ordering.
