HJC R-PHA 71 Full-Face Helmet - hamil mc-3h
(Product No.: BB-107H44-0.83)
Motorbike full-face helmet R-PHA 71 (ECE standard 22.06)
The RPHA 71 is the second generation of this premium sport-touring model, designed for every type of ride, from city traffic to cross-country tours. It has been optimised through extensive wind tunnel testing for a quieter ride, and has all the features of its popular predecessor while enhancing the overall rider experience.
Helmet shell made of Premium Integrated Matrix (PIM) Evo and the high-density EPS for improved impact resistance and maximum protection. The shell is made of carbon aramid fibre, carbon fibre, organic fleece and natural linen fibre. The aerodynamic design of the shell reduces turbulence, air resistance and provides stability at high speeds.
An extra-light carbon version of the RPHA 71 is available.
The two front and two rear vents provide efficient cooling and moisture wicking.
The inner lining is adapted for spectacle wearers. It is antibacterial, ensures improved moisture transport and dries quickly. Reflective stripes on the underside provide more safety. The inner lining and cheek pads are removable and washable.
Pinlock Ready HJ-40 visor: Offers 99% UV protection and an anti-scratch coating. The new visor closure now closes even more securely and is even easier to open. A Pinlock is included.
The RPHA 71 is also compatible with the second generation SMART HJC Bluetooth communication system, which gets integrated into the helmet so the rider can always stay connected and focused on the road.
Integrated sun visor with anti-fog coating. The new mechanism allows the sun visor to slide forward by either 5mm or 10mm, adapting perfectly to your needs.
The closure is an infinitely adjustable double-D ring closure.

HJC Size Chart
HJC offers motorcycle helmets and bicycle helmets with partly different size ranges. The categories are therefore listed separately. Individual models may differ from the general reference chart; product-specific sizing always takes priority.
Motorcycle helmets – general HJC reference chart
Measure the head circumference with a flexible measuring tape around the head. For motorcycle helmets, HJC recommends measuring approximately 2.5 cm above the eyebrows.

Safety note: A size chart is a reference only. A helmet must fit firmly and evenly around the head, must not move out of position and should not create problematic pressure points. HJC warns that wearing the wrong helmet size can increase the risk of injury. Always try the helmet on and follow the product-specific fitting and safety instructions.
