The new X551 from the X-Lite range of Nolan helmets replaces the popular N70 adventure helmet. Every detail has been designed for a 'crossover' use - road/off-road. It is made from composite fibre in three different shell sizes for the perfect fit. The innovative ventilation system includes a wide air intake in the chin, two upper air intakes and a rear extractor guaranteeing a constant airflow. It comes with an internal sun visor, removable/washable interior and is ready for the N-Com X series communication system. The X551 can be used without the adjustable peak and/or visor.
