The HJC RPHA 91 is a modular touring helmet designed around long-distance comfort, a flip-up chin bar and an integrated sun visor. Moto Central's collection includes standard P.I.M. EVO and Carbon versions, solid colours, graphic finishes and model-specific HJ-37 vision-system parts. Every helmet in the range is ECE 22.06 approved, but the correct choice still depends on fit, intended use and the features you will rely on day to day.
The chin bar opens to make stops, conversations and eyewear easier to manage. On the move, use the helmet only in the configurations permitted by its homologation label and manual. A modular helmet should still feel secure around the cheeks and crown when closed.
The standard shell combines HJC's P.I.M. EVO reinforcement materials, while the Carbon version uses P.I.M. EVO Carbon construction. Carbon is the logical comparison if shell material and weight distribution are priorities; the standard version retains the same core RPHA 91 layout and vision system.
The Pinlock-ready HJ-37 visor is specific to the RPHA 91 family. It is paired with the HJ-V17 internal sun visor, which HJC describes as a multi-step shield so its position can be adjusted. Neither part should be confused with the HJ-29 and HJ-V9 system used by the RPHA 90 and 90S.
HJC includes an eyewear-friendly EPS layout, removable and washable comfort padding, front-to-back ventilation and provision for second-generation SMART HJC communication systems, sold separately. Intercom choice should still account for speaker position and your own ear clearance.
Measure around the widest part of your head and compare the result with HJC's current size chart, then assess the helmet on your head. It should hold the crown evenly and grip the cheeks without a sharp pressure point. Fasten it, keep it on for several minutes and check that it does not rotate independently when you move the shell. New cheek pads can feel firm, but a helmet that creates concentrated pain is not the right shape or size.
The collection also includes clear, dark smoke and iridium HJ-37 outer visors. Clear is the flexible option for changing light and night use. Tinted and iridium versions require attention to current UK road-use rules and the conditions in which you ride. For anti-fog support, choose the model-specific DKS465 Pinlock insert. Pinlock lists clear 120 XLT MaxVision, dark smoke and yellow versions for the HJ-37; the insert fits inside the prepared outer visor and is not a replacement shield on its own.
Moto Central lets you compare the standard and Carbon shells, multiple graphics and the correct HJ-37 accessories within one collection. The model-specific product titles make it easier to keep the RPHA 91 system separate from earlier RPHA 90 parts. For more HJC ranges, visit the HJC helmets collection; for visors, Pinlock inserts and interior components across other helmets, use helmet spares and accessories.
The main distinction is shell construction: P.I.M. EVO for the standard model and P.I.M. EVO Carbon for the Carbon version. Both use the RPHA 91 modular layout and HJ-37 vision system.
Choose HJC HJ-37. The matching anti-fog insert code is DKS465.
Yes. HJC specifies the adjustable HJ-V17 internal sun visor for the RPHA 91.
No. The helmet is prepared for compatible second-generation SMART HJC systems, which are separate accessories.
