The Nolan N40-5 06 Classic 305 M helmet is a motorcycle helmet designed for riders seeking reliable protection and comfort. With a polycarbonate shell construction, it offers impact resistance while remaining lightweight and carries the UN/ECE 22-06 certification for European safety standards. The Classic 305 model in white and medium size fits head circumferences of 57 to 58 cm. The integrated JET ventilation system promotes airflow for temperature regulation. As a successor to the N40 series, Nolan continues to focus on rider safety and helmet technology. The inner lining is designed for comfort and is removable for cleaning. The visor mechanism allows for secure closure and easy operation, with options for anti-fog and UV protection with compatible visors. The aerodynamic profile reduces wind noise and turbulence at highway speeds. The chin strap uses a double-D ring fastening system for secure hold. The helmet is designed for street and highway use and meets the requirements for full-face helmets. The polycarbonate material offers durability against environmental influences and light impacts. The design accommodates most eyeglass frames without pressure points. The weight distribution is balanced to minimize neck fatigue on long rides. The outer surface is scratch-resistant and can be maintained with standard cleaning methods. This helmet meets the needs of commuters and travelers who prioritize certified safety features and functional comfort.
