The AGV K-3 SV Birdy motorcycle helmet is an affordable and adaptable full-face motorcycle helmet with an internal drop-down sun visor. It is constructed from HIT-TH (High Thermoplastic Resin) shell in 2 sizes with 4-densities EPS for added aerodynamics with less weight. In addition, it also has IVS (Integrated Ventilation System) ventilation with five large front vents and two rear extractors hollowed in the shell which direct air to the rider's head. The central intake is strategically placed to capture maximum air flow without interference with the internal sun visor. All the air vents and extractors are adjustable for the perfect personalised arrangement. A removable nose guard and wind protector give you versatility along with removable and washable Dry-Comfort fabric interiors. The anti-scratch visor is Pinlock compatible, and the visor is available in 2 different sizes to optimise the match between the visor and shell to reduce drafts and noise. AGV's patented XQRS (Extra Quick Release System) visor mechanism with multiple steps with two mechanisms to change the visor steps option are included in the box. The micrometric retention system gives added convenience, which is compatible with AGV's Share communication system.
