The HJC RPHA 11 Jonas Folger Monster replica motorcycle helmet is a replica of one worn by the MotoGP World Championship rider during the 2017 season. The HJC RPHA 11 is the latest incarnation of HJC's top of the range race helmets, these are finely tuned, premium quality, full-face motorcycle helmets for sports and track-day enthusiasts. The RPHA 11 has HJC's Plus Integrated Matrix (P.I.M.) shell construction of carbon fibre, aramid and carbon-glass hybrid fibres to produce an extremely strong superlight helmet. Designed in HJC's wind tunnel the shell shape maximises its aerodynamic potential with rear and side spoilers to ensure stability at any speed and the detachable chin curtain reduces wind noise and blocks out turbulent airflow. As you would expect from a top-of-the-range HJC helmet, the RPHA 11 has the emergency cheek pads removal system for any emergency situations. The RPHA 11 has an advanced channelling ventilation system incorporated into the liner which allows cool air in and pushes hot, humid air out of the rear. The chin bar and new forehead vents have a simple slider mechanism whilst each of the top vents have a glove friendly rubberised dial allowing you precise control of the airflow. For even more comfort, the helmet's MultiCool anti-bacterial lining wicks moisture away and is removeable and washable. For spectacle wearers the helmet even has a glasses groove. The visor has an enlarged aperture for increased vision, with an enhanced central one touch locking system which enables the visor to be locked closed for high speed track days. The helmet is supplied with a Pinlock anti-fog lens and both clear and smoked visors. The chin strap has a double D-ring retention and the HJC RPHA 11 motorcycle helmet range has a 5-year HJC warranty against any possible manufacturing fault or material defect.
