The HJC RPHA 1N V2 Carbon Snow Diablo is a premium full-face motorcycle helmet for riders who want race-developed construction, precise shield security and serious ventilation. Its carbon fiber shell and aerodynamic design draw on HJC's MotoGP development experience. The MC10SF Snow Diablo graphic combines a semi-flat black and white finish with vivid green accents and distinctive snowman artwork.
Carbon Fiber Construction and Racing Credentials
The carbon fiber outer shell combines strength with low weight. HJC developed the shell shape using feedback and data from MotoGP riders, while the rear spoiler helps manage airflow and stability at speed. A titanium double D-ring retention system provides a secure, adjustable fastening.
- Meets DOT FMVSS 218 and ECE 22.06 standards.
- FIM FRHPhe-02 homologation for current racing requirements.
- Full-face coverage with a fixed chin bar and race-focused design.
What Has Improved Over the RPHA 1N
- Carbon fiber shell: this V2 Carbon model uses a carbon fiber outer shell in place of the original RPHA 1N's PIM+ construction.
- Updated FIM homologation: the V2 Carbon meets FRHPhe-02, compared with the original RPHA 1N's FRHPhe-01 approval.
Ventilation and Interior Comfort
HJC's Advanced Channeling Ventilation System uses five intake vents and four exhaust outlets to move air from front to back, helping carry heat and humidity out of the helmet. The antibacterial interior wicks moisture and dries quickly, with removable, washable crown and cheek pads for easier upkeep.
The cheek pads are interchangeable across helmet sizes, and the emergency cheek pad release system allows trained responders to remove the pads more easily. Eyeglass-friendly EPS shaping accommodates glasses or sunglasses. Built-in speaker pockets provide space for compatible Bluetooth communication speakers; a communication system is sold separately.
HJ-35 Shield System
The Pinlock-ready HJ-35 shield provides 99% UV protection and an anti-scratch coating. An enhanced dual-lock mechanism secures the shield, while HJC's EASY attachment system allows tool-free shield changes. Tear-off posts are installed for use with tear-off film.
A Pinlock 120 XLT anti-fog insert and an additional dark smoke shield are included. The insert helps resist fogging in changing conditions. Use the dark smoke shield only in suitable daylight conditions and follow HJC's installation and care instructions.

Size Chart and Fit
The measurements below follow HJC's model-specific RPHA 1N V2 Carbon size chart for the sizes offered here.
| Helmet size | Centimeters |
|---|---|
| Small | 55-56 cm |

Use a flexible tape around the widest part of your head, approximately one inch above your eyebrows and over the fullest part at the back. Keep the tape level and repeat the measurement. Use the chart as a starting point, then try the helmet on: it should feel snug and evenly supported without painful pressure points. With the chin strap fastened, it should not rotate freely or roll off. Head shape matters as well as circumference, so a fit check is recommended before riding.
