The Suomy S1-XR GP isn’t just a helmet; it’s a professional racing instrument. Developed and fine-tuned in the wind tunnels of Italy with the direct input of MotoGP World Champion Pecco Bagnaia, the S1-XR GP represents the absolute pinnacle of Suomy’s engineering. It is designed specifically for the rider who spends their time at full lean, demanding zero aerodynamic lift and a peripheral view that redefines track awareness.
Aerodynamics: The CX 0.33 Benchmark
In racing, air is the enemy. The S1-XR GP boasts an industry-leading drag coefficient of CX 0.33 in a straight line and CX 0.39 during cornering.
-
Stabilized Spoiler: The integrated rear spoiler works in tandem with the shell’s “teardrop” geometry to eliminate the “sail effect” and helmet buffeting at speeds exceeding 200 mph.
- Engineered Neutrality: The helmet is weighted and shaped to remain perfectly neutral, reducing neck strain during high-G braking and rapid transitions.
Field of Vision: 210° Awareness
The S1-XR GP offers a “panoramic” experience that is critical for competitive racing.
- Peripheral Mastery: A horizontal field of view of 210° allows you to see rivals in your periphery earlier.
- Vertical Range: The 92° vertical field of view is optimized for a full “pro-tuck” position, ensuring you can see the horizon and upcoming markers even when your chin is on the tank.
- Racing Lock System: The metal alloy visor mechanism features a patented “Racing Lock” to prevent the shield from popping open during a high-speed slide.
🛡️ Technical Specifications & Safety
| Feature | Details |
| Shell Material | Tricarboco (Carbon / Kevlar / Fiberglass Blend) |

| Interior | Hydrocool Technical Textile (Removable/Washable) |
| Retention | Light Alloy Double D-Ring |
❓ FAQ: Expert Performance Answers
“What is ‘Tricarboco’ and why is it better than standard carbon?”
Tricarboco is Suomy’s proprietary composite that weaves together carbon fiber with different weights, aramid (Kevlar) for abrasion resistance, and fiberglass for impact dispersion. This “sandwich” construction allows the shell to be lighter than pure carbon while meeting the incredibly high energy-absorption standards of the FIM certification.
“Does this helmet support a hydration system?”
Yes. The S1-XR GP is Hydration Ready. The chin bar and internal liners are pre-configured to accept a camel-bag tube, allowing you to stay hydrated during grueling long-distance races or summer track days without modifying the helmet.
“How does the ventilation perform in high-humidity racing?”
The S1-XR GP utilizes a Venturi Effect extraction system. Hot air is sucked out of the rear extractors by the low-pressure zone created by the spoiler. When combined with the included Pinlock MaxVision 120, the helmet is virtually immune to fogging, even in the most intense racing conditions.
Peer Insight: If you are transitioning from a street-focused helmet, the first thing you’ll notice is the “tight” fit around the base. This is intentional; it’s designed to seal out wind noise and prevent the helmet from lifting. Give the Hydrocool liners about 10–15 hours of ride time to fully contour to your facial structure.
