The NHK K5R SV is a full-face motorcycle helmet designed to meet the needs of modern riders who demand safety, comfort, and aggressive styling in one complete package. Built for daily use and long-distance riding alike, it blends aerodynamic design with functional features for both performance and practicality.
Design & Appearance
With its sharp lines, aerodynamic contours, and bold graphic options, the K5R SV delivers a sporty, race-inspired look. Whether in matte or glossy finishes, the helmet’s visual appeal is matched by its purposeful design, making it suitable for riders who want to stand out while staying protected.
Outer Shell
Constructed from an advanced thermo-polymer resin, the shell offers solid impact protection without excessive weight. Its aerodynamic shape reduces wind resistance and features a built-in rear spoiler to enhance stability at higher speeds, improving overall ride comfort and performance.
Ventilation System
The K5R SV is engineered for efficient airflow. Multiple front intake vents (at the chin and top) and rear exhaust outlets work together to maintain airflow throughout the helmet. This helps to reduce heat buildup and keeps the rider cool, especially during long rides or in hot weather conditions.
Visor & Sun Shield
Equipped with a clear, scratch-resistant outer visor that is Pinlock-ready (anti-fog insert sold separately), the helmet provides excellent visibility in various riding conditions. An internal drop-down sun visor offers added convenience and eye protection in bright sunlight. The quick-release visor mechanism allows for fast, tool-free visor changes.
Safety
Certified under the latest ECE 22.06 safety standard, the K5R SV meets updated European regulations for impact protection. A secure Double D-ring chin strap ensures proper fit and retention, enhancing rider safety in the event of an accident.
Interior & Comfort
Inside, the helmet features a fully removable and washable inner liner made of hypoallergenic, moisture-wicking fabric for enhanced comfort and hygiene. Ergonomic cheek pads offer a snug fit, while built-in speaker pockets accommodate Bluetooth communication systems or audio accessories.
Weight & Balance
With an average weight of approximately 1,450 grams (±50 g), the helmet offers a well-balanced feel that minimizes fatigue during longer rides. Its lightweight construction, combined with aerodynamic shaping, makes it suitable for daily commuting and weekend touring alike.
Ideal For
The NHK K5R SV is ideal for riders looking for a full-face helmet that delivers modern safety certifications, versatile visor functionality, strong ventilation, and comfort for daily or long-distance use. It’s particularly well-suited for riders in warmer climates, where airflow and interior cooling make a real difference in everyday riding conditions.
