Perfect for standard intermediate head profiles.

Designed for intermediate oval head shapes; offers a slightly roomier fit compared to the TC-2 due to the modular hinge mechanism.

How to measure

Wrap a cloth measuring tape around your head just above your eyebrows and ears. Pull the tape comfortably snug, read the length, and repeat for consistency.

Design Concept & Background

"Ride Safe"

Engineered for adaptable touring, the Shoei Neotec 3 Grasp TC-1 is engineered for seamless transitions between open-face city stops and full-face highway cruising across highway and urban riding. Its Advanced Multi-Composite (Carbon-Aramid-Glass / AIM+) shell tips the scales at 1593g, channeling boundary-layer airflow to maintain a ~87 dB acoustic cabin profile while meeting DOT, ECE 22.06 impact standards. The interior leverages moisture-wicking antibacterial liners contoured for an Intermediate Oval fit, integrating eyeglass channels and track-proven Double D-Ring retention.

Engineering & Biomechanical Safety Analysis

Features Advanced Integrated Matrix Plus (AIM+) 6-layer organic fiber and fiberglass composite shell paired with CWR-F2 3D injection-molded visor with Pinlock EVO lens inserts and vortex generators along the shield edges. The interior utilizes Dual-layer multi-density EPS with internal cooling channels and 3D Max-Dry custom cheek pad fitment with pre-shaped speaker cutouts for seamless Bluetooth comms integration.

The Neotec 3 Grasp TC-1 is engineered as a high-integrity Modular protective system, utilizing a structural shell constructed from AIM. This structural layup is engineered to provide progressive kinetic energy dissipation during impact deceleration, distributing localized shock across outer lamina layers while minimizing deformation transfer into the internal multi-density EPS liner.

Certified to ECE 22.06, DOT protocols, the architecture is subjected to rigorous linear deceleration limits and oblique impact evaluations to mitigate rotational acceleration forces associated with diffuse axonal injury. For a deeper breakdown of rotational thresholds and impact testing speeds, consult our ECE 22.06 vs DOT vs SNELL engineering benchmark.

Internal geometry follows a Intermediate Oval cranial profile, designed to mitigate focal pressure hot spots across the parietal ridges while maintaining uniform radial clamping pressure along the zygomatic arch. Riders seeking optimal retention stability and break-in guidance should review the cranial aspect ratios and head shape guide as well as our 3D cheek pad density protocol.

Shell composite integrity and acoustic sealing are further optimized through channelized EPS porting and aerodynamic laminar profiling. To learn how shell composites resist stress cracking under prolonged environmental cycling, inspect the composite material comparative matrix.
