Engineering & Technical Analysis

Die HJC RPHA 91 Apex Red zeichnet sich durch die fortschrittliche PIM Evo-Schalenkonstruktion aus, die überlegene Stoßfestigkeit und leichtes, langlebiges Design bietet. Das modulare Design sorgt für Vielseitigkeit, während die ovale Kopfform für einen bequemen Sitz bei den meisten Fahrern sorgt. Der Helm verfügt über eine hochwertige Belüftung mit verstellbaren Luftkanälen für optimale Kühlung. Die Sicherheitstechnik umfasst einen mehrschichtigen EPS-Inliner und eine Pinlock-kompatible Visier für weniger Beschlagen. Das Innenfutter besteht aus feuchtigkeitsableitendem, antibakteriellem Stoff für Komfort auf langen Fahrten.
