RPHA 91 Modular Helmet – Combust – MC3HSF – Small
The HJC RPHA 91 Modular Helmet in the Combust design offers a premium combination of safety, comfort, and advanced features for riders seeking top-tier head protection. Constructed with a shell material that includes carbon-aramid fiber, carbon fiber, glass fiber, organic non-woven fabric, and natural linen fiber, this helmet provides enhanced shock resistance while maintaining a lightweight profile for extended riding comfort. Its innovative shell design ensures optimal energy absorption and durability, making it suitable for diverse riding conditions. The helmet features the HJ-37 Visor, which is Pinlock® 120XLT® prepared, offering 99% UV protection and an anti-scratch coating for clear visibility and long-lasting performance. The dynamic multi-step sun visor can be swiftly activated via a bottom-positioned mechanism, allowing you to position it up to 10 mm closer to your face for personalized shading and reduced glare at a moment’s notice. The eyebrow ventilation system acts as a defogging and airflow channel, enhancing comfort and visibility during rides. The RPHA premium fit interior, made of anti-bacterial, moisture-wicking, and quick-drying fabric, ensures a snug, comfortable fit while maintaining hygiene. Interchangeable 3D contour cheek pads allow for a customizable fit across all sizes, and removable, washable crown and cheek pads simplify maintenance. The chin bar features a dual-axis pivot mechanism, achieving a close fit to the helmet shell to minimize wind noise and air resistance. Its streamlined design incorporates a retractable mechanism for easy opening, promoting aerodynamic efficiency. The helmet integrates Smart HJC 2nd Generation technology, an all-in-one system designed for seamless integration with compatible devices, ensuring optimal weight distribution and aerodynamic performance. Co-developed with SENA, these smart features are sold separately but enhance ride connectivity and safety. Compatible with models such as RPHA 71, RPHA 91, RPHA 31, and i71, this helmet combines advanced safety features with rider-focused comfort, making it an excellent choice for motorcycle enthusiasts demanding high performance and innovation.
