Nolan N91 Helmet Nolan N91 is the new full-face modular helmet by Nolan and is an evolution of the best-selling N90. The product of the most up-to-date studies on design and comfort, the N91 features a modern and styled look, captivating color combinations and painstaking attention to details to produce a comfortable, sophisticated helmet, suitable for touring and urban riding alike. The Nolan N91 is equipped with the Microlock2 (patent pending) double lever retention system. This system consists of a thermoplastic ergonomic opening lever, and of a second aluminum toothed and holding lever.
