G4.2 PRO This is Grex’s road crossover built on the solid foundations of the Nolan N43 AIR model, which has become an icon in recent years, so much so as to also be appreciated by a number of Hollywood stars, confirming the already popular technical characteristics. This year, the range is characterized by a revision of the finishing on the upper air intakes, the front air intake and the rear extractors. A compact design, P/J homologation, ultrawide visor, VPS (Vision Protection System) sunscreen with UV 400 protection, an efficient ventilation system, Microlock retention system with micrometric adjustment, good overall comfort and set up for the N-Com communication system make the G4.2 PRO an interesting product for those in search of a road crossover helmet offering value for money and the guarantee of Nolan’s experience..
    The helmet is approved in P/J double configuration, as the removable protective chin guard has passed the homologation tests required by UN/ECE regulations for full-face helmets.
    The large surface of the S/R (Scratch Resistant) visor makes it possible to have a broader view, also lateral, thus highly increasing active safety. It is also able to protect the rider’s face from water and wind while guaranteeing air circulation within the helmet, if used in jet configuration.
    Supplied (according to the segment) and with silicone-sealed profile (FSB – Full Silicone Border). Thanks to the exclusive patented adjusting system adopted by the Nolangroup, the stretch of the Pinlock® inner visor can be adjusted, operating from the outside of the visor and making removal of the inner visor unnecessary.
    Moulded out of LEXAN™, it is S/R (Scratch Resistant) and F/R (Fog Resistant) treated and offers UV protection up to 400 nanometres. It can be easily removed for maintenance and cleaning. LEXAN™ IS A TRADEMARK OF SABIC
    The exclusive complete and extremely efficient ventilation system uses three different systems of air-flow management via a front intake, two upper intakes and two rear extractors which allow optimal air circulation inside the helmet. An opening located in the lower part of the visor further contributes to ventilation around the mouth area, limiting fogging and the formation of condensation on the visor itself when the helmet is used in full face configuration
    The helmet is set up and approved with installed N-Com communication system. N-COM COMPATIBILITY B901 S series - B601 S series - MCS II
