Just 1 helmet was developed with the primary goal of safety and comfort for the rider. During the design phase, the helmet was designed from the inside out in order to have the best possible fit and a radical ventilation system.
The external shell is made of full carbon fiber. This makes the helmet extremely rigid and incredibly lightweight. J12 helmet uses two outer shell sizes, in order to provide the smallest and lightest fit possible for the rider. The design of the shell was conceived by studying collision angles. The design team incorporated that data into a model that also accounts for and effectively integrates the helmet as an extension of the rider. This makes the helmet feel as though it is truly part of the rider. Ultimately, the perfect integration also includes the exclusive NBFF (Neck Brace Front Fit), which makes the J12's bottom profile the only helmet in the world that is fully compatible with the entire surface area of a neck brace.
