Engineering & Technical Analysis

Die HJC RPHA 91 Anthrazit zeichnet sich durch die fortschrittliche PIM Evo-Schalentechnologie aus, die für überlegene Stoßfestigkeit und leichtgewichtige Haltbarkeit sorgt. Das modulare Design vereint den Schutz eines Vollvisierhelms mit der Flexibilität eines Klapphelms, während ein hochentwickeltes Belüftungssystem für optimalen Luftstrom und Komfort unter allen Bedingungen sorgt. Die ovale Kopfform bietet einen eng anliegenden, sicheren Sitz, und die hochwertige Innenpolsterung steigert den Komfort auf langen Fahrten. Sicherheitsmerkmale umfassen einen mehrschichtigen EPS-Innenliner und eine verstärkte Kinnpartie für zusätzlichen Schutz.
