The HJC RPHA 1N Red Bull Austin GP Helmet was developed after several years of focused efforts and crucial feedback from top world class athletes in MotoGP. The RPHA 1N is the very same FIM certified model used by HJC’s world-class athletes in both MotoGP and World SBK. FIM Racing homologation standards and provides the highest level of protection, even against glancing impacts that can cause rotational motion.
Reinforcement materials, including carbon and carbon-glass hybrid fabric, provide enhanced shock-resistant performance for a more comfortable and lighter helmet. Moisture-working and antibacterial SilverCool interior combined with an Advanced Channeling System (ACS) ensure you stay cool when the track heats up. The anti-scratch coated HJ-35 face shield is pinlock and tear-off ready for optimal visibility and performance.
Note: Ships with clear HJ-35 face shield and clear extended aero-spoiler
