The Nolan X-804 RS Ultra Carbon is the flagship helmet of Nolan's new Xseries range. Born from the legacy of the X-803 and engineered for dedicated racers, it is a helmet inspired by great sporting achievements in MotoGP and Superbike, forged through the experience of champions. It is the best-in-class performance branded Nolan. Made from carbon fibre construction, it offers four outer shells that provide unmatched aerodynamics and superior comfort. It features an advanced version of the Nolan Emergency Release System (NERS) to ensure a swift and secure removal in critical situations; at the same time, the traditional assembling system simplifies the assembly and disassembly process without using hooks. The Nolan X-804 RS Ultra Carbon helmet guarantees that your visor remains securely in place during intense racing conditions, preventing the risk of accidentally opening the visor at high speeds. Nolan's exclusive Racing Air Flow system optimises ventilation for racing conditions, keeping you cool and focused even at high speeds. The lining is adjustable to perfectly adjust the internal padding for the perfect custom fit for superior comfort. Nolan's RAS (Racetrack Aerodynamic Spoiler) enhances aerodynamic efficiency, contributing to the helmet's remarkable performance on the racetrack. Its shape has been designed to maximise the aerodynamic performance after several CFD (Computational fluid dynamics) simulations. A complete ventilation system with vents and exhausts gives superior airflow. It has an additional visor with a flat race visor and scratch-resistant treatment on both sides. The visor aperture is ultra-wide for exceptional vision and offers a safety visor lock system with a safety screw lock visor mechanism. The visor is also Pinlock ready. A breath deflector and wind protector prevent wind ingress and fogging up, and this has a double D ring fastening for adjustable and secure closure. It comes with a clear visor, dark smoke visor and a Pinlock insert.
