The Arai RX-7V Evo in the Katsuyuki Nakasuga4 Replica livery captures the exact graphic identity worn by Yamaha's celebrated Japanese test rider and multiple Suzuka 8 Hours winner — rendered in a gloss finish that does full justice to the original. This is a helmet for those who understand that design and protection are not competing priorities, but two expressions of the same commitment to excellence.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eOfficial Katsuyuki Nakasuga4 Replica livery in a gloss finish — a collector-grade graphic faithful to the Suzuka race-winning original\u003c\/li\u003e\n\u003cli\u003eECE 22.06 homologated — meets the most rigorous current road and circuit safety standard\u003c\/li\u003e\n\u003cli\u003eArai's fibre-glass composite shell engineered around the Rounder, Smoother, Stronger philosophy for optimal glancing-off performance\u003c\/li\u003e\n\u003cli\u003eVAS MAX Vision visor fitted as standard for an exceptional field of view at speed\u003c\/li\u003e\n\u003cli\u003ePinlock anti-fog insert included — reliable clear vision in all conditions\u003c\/li\u003e\n\u003cli\u003eEco Pure interior liner: fully removable, machine washable and antibacterial\u003c\/li\u003e\n\u003cli\u003eFive-year Arai manufacturer's guarantee\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eDesign, Finish and Heritage\u003c\/h2\u003e\u003cp\u003eThe Katsuyuki Nakasuga4 Replica is not a generic replica colourway — it is a direct visual reference to one of Japanese motorsport's most respected figures. Nakasuga's decades of service as a Yamaha factory test and race rider, combined with his endurance racing pedigree at the Suzuka 8 Hours, give this livery genuine provenance. The gloss lacquer is applied over the RX-7V Evo's fibre-glass composite shell, preserving every graphic detail with the depth and clarity the design demands. For collectors and committed racers alike, the finish elevates this helmet beyond its already formidable functional specification.\u003c\/p\u003e\u003ch2\u003eShell Construction and Protection\u003c\/h2\u003e\u003cp\u003eThe RX-7V Evo is the direct successor to the acclaimed RX-7V, refined to meet the demands of ECE R22-06 certification. Arai's fibre-glass composite construction is aerodynamically profiled to remain stable at high speed while the shell's smooth, rounded geometry promotes safe deflection on impact — the core principle behind every Arai product. The integrated Brain Protection System adds a further layer of safety engineering that goes beyond what homologation alone requires.\u003c\/p\u003e\u003ch2\u003eComfort and Ventilation\u003c\/h2\u003e\u003cp\u003eThe EVO revision brings relocated lateral air channels that improve both aerodynamic efficiency and airflow through the helmet. New cheek pads use a hook-retention system that makes removal and refitting straightforward — important for emergency responders and useful for everyday cleaning. The Eco Pure liner wicks moisture, resists bacteria and comes out for washing without tools. The closure is a double-D ring — the enduring choice of circuit racing for its security and simplicity. Note that the race-oriented fit of the RX-7V Evo means it is not ideally suited to spectacle wearers.\u003c\/p\u003e\u003ch2\u003eVisor and Visibility\u003c\/h2\u003e\u003cp\u003eThe VAS MAX Vision visor is Arai's widest-aperture shield, designed to give riders the broadest possible peripheral view — critical at track pace where awareness is everything. The visor mechanism accepts a Pinlock 120 insert, which is supplied in the box, providing reliable anti-fog performance across a wide range of ambient temperatures. The visor is also prepared for compatibility with select communication and intercom systems.\u003c\/p\u003e\u003ch2\u003eSize Guide\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eXS: 53–54 cm\u003c\/li\u003e\n\u003cli\u003eS: 55–56 cm\u003c\/li\u003e\n\u003cli\u003eM: 57–58 cm\u003c\/li\u003e\n\u003cli\u003eL: 59 cm\u003c\/li\u003e\n\u003cli\u003eXL: 60–61 cm\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003ePlease note: in size XL the outer shell steps up one size (86 to 88), which may affect fit perception.
