Ready to purchase now at Bush 2 Bitumen Motorcycle Accessories, HJC RPHA 11 CARBON


Ready to purchase now at Bush 2 Bitumen Motorcycle Accessories, HJC RPHA 11 CARBON NAKRI MC1SF HELMET 


The HJC RPHA 11 Carbon Full-Helmet has now been released following the HJC RPHA 11’s success, the successor of the popular HJC RPHA 10. Though the helmets are largely similar, HJC’s use of carbon fiber structure for extreme performance at maximum speeds has taken the next step in the premium RPHA line. This has, again, resulted in a first-class racing helmet. The Helmet shell is aerodynamic, which keeps the helmet stable at high speeds, and the newly developed spoiler prevents a lift at high speed. This helmet’s competitors include the Arai RX-7V, X-Lite X-803 RS Ultra Carbon, Shoei X-Spirit III, Shark Race-R Pro GP, and the AGV Pista GP RR.

Safety HJC RPHA 11 Carbon

The Helmet shell is made of P.I.M. (Premium Integrated Matrix) Plus Carbon Fiber shell structure for extreme performance and enhanced shock resistance. This material consists of Fiberglass, Aramid and even more Carbon. This combination is extremely strong and light at the same time. In case of emergency, the cheek pads can easily be removed thanks to the EQRS (emergency quick release system). The visor has a wider field of view for better vision.

Ventilation HJC RPHA 11 

The ventilation that was so strong on the RPHA 10 has been optimized even further on the HJC RPHA Eleven Carbon. There are air intakes with multiple positions on top of the helmet. The button for the different positions of the air inlets is also glove-friendly. ACS (Advanced Channeling Ventilation System) is how HJC ensure that there is airflow to remove the heat and humidity from the interior. The cool air flows through the helmet to make the wearing comfort optimal in the helmet.

Acoustics HJC 

The improved connection of the visor to the HJC R PHA 11 Carbon’s shell and the aerodynamic shape with its top spoiler make the helmet quieter. The helmet shell is available in 3 sizes, making the fit even closer on the head.

Visor HJC 

The visor is HJC’s Max Vision Pinlock and Tear-Off prepared. It fits even better on the shell thanks to the same smart design. This strong design results in less wind noise coming in. Thanks to the RapidFire visor mechanism, the visor can easily and quickly be changed without any tools. The visor also has a closing button for extra safety so that it does not open unintentionally. The wider eye port provides better peripheral vision for riders than before and it is also available with dark smoke shields for sunny days.

Lining HJC 

The HJC RPHA 11 Pro Carbon helmet has a Multicool (moisture wicking and quick drying) inner lining. The crown and cheek pads are fully removable, washable, and anti-bacterial. It also sports a wider eye glasses and sun glasses friendly EPS shape. The lining is extremely comfortable and fresh.
