We are pleased to announce the release of KAMUI-5 SPRIA, a new graphic model added to the new-generation full-face helmet KAMUI-5, which redefines the standard of comfort through advanced functionality and refined design. SPRIA features sharp, flowing linework designed to harmonize with the sculptural form of the helmet shell. The dynamic accent lines emphasize the silhouette, creating a sporty yet composed visual presence. The result is a sophisticated graphic that enhances the overall elegance of the KAMUI-5 design. The color lineup includes Flat Black Red, Flat Black Gray, and Pearl White Silver. Pearl White Silver ★About KAMUI-5 The KAMUI-5 is equipped with the CF-2 UIC Shield (UIC Clear) as standard, featuring Teijin's heat-shielding material that cuts 99% of UV rays and 74% of IR rays. This advanced shield suppresses temperature rise inside the helmet caused by solar radiation and reduces heat transfer to the interior while maintaining clear visibility. The helmet also features a large inner sunshade that performs effectively in strong sunlight and glare conditions, along with a two-stage chin ventilation system that allows riders to adjust airflow according to riding situations. In addition, the new dual-axis shield ratchet mechanism achieves stable operation while minimizing distortion and improving sealing and quietness. A completely redesigned interior offers smooth on/off usability and a secure, natural fit that softly wraps around the head, ensuring comfort even during long rides. With its advanced ventilation system, expanded field of vision, and refined fit, the KAMUI-5 represents a new-generation full-face helmet that delivers exceptional comfort, confidence, and usability on every ride. ■KAMUI-5 SPRIA ・Equipped with "CF-2 UIC Shield (UIC Clear)" made with IR-cut material.
