Shoei VFX-EVO HelmetGet ready to rumble with the Shoei VFX-EVO Helmet, the next iteration of the popular VFX-W.The VFX-EVOs liner incorporates the unique M.E.D.S. ( Motion Energy Distribution System Motion Energy Distribution System (M.E.D.S.) relies on a unique framework in the design of the helmet's dual-layer, multi-density EPS liner. The EPS inner layer is secured to the outer layer using sacrificial EPS columns. Upon impact, this framework allows for a calculated amount of "swing" between the two layers, which is the key to energy absorption. MEDS results in significantly reduced rotational forces reaching the riders head. ), a specially inserted module of the EPS liner Expanded polystyrene (EPS) is a rigid, energy absorbing foam. In the helmet industry, EPS is the most common means of energy management to protect the brain. Generic EPS is often referred to as Styrofoam (a trademarked name owned by the Dow Chemical Company). Premium helmet producers utilize multi-density EPS liners to balance comfort, safety and performance. designed to absorb sudden impacts by reducing rotational acceleration to the head in the event of a crash. Shoei's in-house testing showed rotational energy to be reduced by 15% in comparison to that of the VFX-W off-road helmet. The shell is constructed with high performance AIM+ (Advanced Integrated Matrix Plus Multi-Fiber), a combination of fiberglass and organic fibers. The result is a rigid, ultra-lightweight, yet elastic structure.The mud guard is specially shaped so as not to interfere with the wearing of goggles. Dedicated plastic tabs help hold the mud guard firmly in place during serious off-road riding conditions. The braced nose cover has been designed to improve safety: it features mesh to filter dirt and dust, and aluminum mesh to prevent roost from entering the mouth and is easily removed for cleaning and maintenance. The VFX-EVOs newly-designed, adjustable visor designates the top position on the helmet as default, based on the preference of many top-ranked riders. A straight line is formed from the visor top to the helmet shell to ensure upward visibility. The adjustment system is facilitated with a special screw fixing nut, installed beneath the upper center of the visor, holding it firmly in place and keeping the nut from coming loose and falling into the helmet.Features: Lightweight, Advanced Integrated Matrix Plus (AIM+) shell construction combines high performance fibers with organic fibers to create a shell structure that is lightweight, rigid and resilient Expanded rib shapes across the rear enhances strap-holding performance for goggle wearers Four shell sizes increase fit options that help comfortably fit most head sizes Aerodynamic properties are maximized through extensive wind tunnel and rider testing Extra front intake vents combine with rear exhaust outlet vents and an enlarged neck outlet vent to maximize flow-through ventilation Cool air passes through the front intake vents, cools the helmet interior, and is exhausted through the rear vents by the force of negative air pressure 3D Max-Dry removable liner system material absorbs two times its weight in moisture E.Q.R.S. (Emergency Quick Release System) features special straps under the cheek pads which allow them to be easily removed, so the helmet can be quickly taken off by emergency personnel after an accident Aggressively shaped, streamlined V-470 visor is easily installed or removed with three external screws, using the center screw to adjust for optimal visibility M.E.D.S (Motion Energy Distribution System), a flexible insert that helps absorb sudden impact to the head in the event of a crash Larger mouth piece for improved air intake Ergonomically shaped mud guard Snell M2015 and DOT approved Note: Due to manufacturer restrictions, Shoei products can only be shipped to addresses within the United States.
