The SHOEI X-15 Marquez 9 FR TC-10 (often referenced locally as the Marquez Barcelona or Marquez Dazzle graphics under the TC-10 color code) is a top-tier, race-certified full-face helmet. It serves as the flagship aerodynamic racing model developed by SHOEI Worldwide for extreme performance exceeding speeds of 350 km/h.

• Advanced Aerodynamics: Features a completely redesigned aeroform shape, rear stabilizer air tunnels, and a lower air spoiler to eliminate drag and lift at racing speeds. 
• Safety Construction: Built with SHOEI’s proprietary multi-ply AIM+ (Advanced Integrated Matrix Plus Multi Fiber) shell, paired with a multi-density EPS liner and an Emergency Quick Release System (E.Q.R.S.). 
• Enhanced Field of Vision: The eye port has been raised by 5 mm compared to its predecessor (X-Fourteen), creating a much wider upper field of vision when tucked into a tight racing position. 
• Optimized Cooling & Ventilation: Integrates deep internal air channels (1.5 times deeper than previous generations) alongside an innovative cheek pad cooling ventilation system. 
• Visor System: Uses the CWR-F2R racing shield equipped with a secure center-locking mechanism to prevent accidental opening and seal tightly against rain and heavy wind. 
• Adjustable Custom Fit: Employs a 6-part modular split center pad system and multi-layered cheek pads, allowing riders to customize internal tightness.
