Born from the golden age of motorsport, the Simpson M30 Carbon carries forward the iconic silhouette of the legendary RX-1, the same profile worn by F1 and motorcycle racing icons of the 1970s and early 80s. Every curve honours that heritage, yet beneath the surface lies the engineering of a true modern classic. This is a helmet that doesn't just look the part; it earns it. For riders who understand that style and substance are inseparable, the M30 is a statement as much as it is a piece of safety equipment. The M30 is built around a lightweight tri-blend composite shell, available in three sizes for an optimally balanced fit and outer profile. Inside, a multi-density EPS liner manages impact energy across a range of speeds, while the fully removable, anti-microbial and hypoallergenic comfort liner keeps long rides comfortable and fresh. The scratch-resistant, anti-fog visor comes paired with a Pinlock® Max Vision 120 insert as standard, because clarity at speed is non-negotiable. Whether you're carving through mountain passes or navigating city streets, the M30 is engineered to perform wherever the road takes you. Designed for the connected, safety-conscious rider, the M30 integrates generous ear pockets and channelled cable routing for seamless communication system compatibility. Every helmet ships with TwiceMe® NFC technology for instant access to vital rider information and is pre-fitted for the Eject® emergency helmet removal system, a feature that could make all the difference in an emergency. Backed by ECE 22.06 certification, the M30 proves that looking fast and riding safe are never mutually exclusive. It is the rare helmet that future generations will look back on as a classic, just as we do the RX-1 today.
