SHOEI · X-Fifteen · Full Face
The SHOEI X-Fifteen Diggia2 is a full-face motorcycle helmet that channels Fabio Di Giannantonio’s racing spirit into a track-focused design built around high-speed stability and rider comfort. With SHOEI’s AIM+ shell construction and an Impact Absorbing Liner, it’s designed for riders who prioritize a purpose-driven fit and a race-developed profile.
This Diggia2 graphic is offered in Diggia2 TC-1 and Diggia2 TC-3, with sizing from X-Small through XX-Large. The X-Fifteen platform pairs a CWR-F2R shield with a Defogger Ventilation System and includes a Breath Guard, Chin Curtain, and Anti-fog Sheet to help manage airflow and fogging in demanding conditions. Safety certification is listed as Snell M2025R, DOT and ECE R22.06 Approved.

Built on the X-Fifteen platform, this helmet uses SHOEI’s Multi-Ply Matrix AIM+ shell with a Multi-Piece, Multi-Density EPS liner.

Shield
The X-Fifteen uses the CWR-F2R shield system. SHOEI’s 3D injection-molding process is designed to provide a distortion-free view across the entire eyeport, supporting a consistent sight picture whether the rider is tucked in or upright.

Comfort
Inside, the X-Fifteen features a 3D Max-Dry Custom Interior System II that is fully removable, washable, adjustable, and replaceable. The fit-and-feel focus is intended to support long sessions in a full-face helmet environment without giving up a secure, track-oriented setup.


Ventilation
Ventilation is a key element of the X-Fifteen design. It features seven (7) closable air intakes and six (6) exhaust outlets, with shaping and placement intended to promote airflow and negative air pressure suction. SHOEI also notes significant improvements to the cheek pad cooling system to bring refreshing air in and clear humidity from the rider’s face more efficiently.

Aerodynamics
SHOEI developed the X-Fifteen’s aerodynamic behavior with extensive study and refinement in its wind tunnel facility. The goal is a shape that supports high-speed stability and balanced aerodynamic performance measurables, which matters most when riding at racing pace or spending time in a tuck.

Construction
The Diggia2 graphic brings a distinct race-inspired look to the X-Fifteen platform while keeping the same core X-Fifteen specifications riders expect, including AIM+ shell construction, the CWR-F2R shield, and a listed weight of 3.78 lbs.
