Engineering & Technical Analysis

Der HJC i90 Tech TC-5 überzeugt mit einer leichten und robusten Polycarbonat-Schale für maximale Sicherheit. Dank seines modularen Designs mit abklappbarem Kinnbügel bietet er vielseitige Einsatzmöglichkeiten, während die ovale Kopfform für einen komfortablen Sitz sorgt. Das Helmmodell verfügt über einstellbare Belüftung zur optimalen Luftzirkulation und eine feuchtigkeitsableitende Innenausstattung für langanhaltenden Tragekomfort. Zu den Sicherheitsfeatures zählen ein mehrlagiger EPS-Innenschaum zur Stoßdämpfung sowie eine Pinlock-kompatible Visierbeschichtung zur Reduzierung von Beschlagbildung.
