Features Polycarbonate shell P/J homologation, detachable chinguard Pinlock-ready anti-scratch visor Sunscreen UV-400 protection Microlock retention system N-COM ready Homologated UN/ECE 22-05 P/J Homologation 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. Ultrawide visor 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. Pinlock® Fog-resistant inner visor Available as an accessory 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, acting from the exterior of the visor, without the necessity for dismantling. VPS sunscreen 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. Ventilation system 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. Set up for N-COM communication system The helmet is set up and approved with installed N-Com communication system. N-COM compatibility B901 S series - B601 S series MCS III S series SHARP – THE HELMET SAFETY SCHEME Nolangroup proudly underlines that all of its products - Nolan, X-lite and Grex - tested by SHARP, the prominent independent test system run by the British Government, have obtained at least four stars. Furthermore, all “flip-up” helmets have received the highest possible rating in terms of chin guard latch reliability. This means that, for each of the products tested by SHARP, the chin guard remains completely closed during each of the 30 impacts. Note Please note that as long as nothing else is written in the article description, all helmets that have a visor as standard will be delivered with a clear one, even if it s shown differently.
