Nexx Y.100 Core: Street Performance & Modern Comfort
The Nexx Y.100 Core Helmet is designed for the versatile street rider. Whether you are navigating city traffic or heading out for a weekend tour, the Y.100 Core delivers a lightweight, aerodynamic profile that minimizes wind noise and maximizes safety.
Advanced Polyfusion Shell & Safety
The Nexx Y.100 Core Helmet utilizes Polyfusion Shell Technology, offering a compact and lightweight (1575g) fit without compromising impact resistance. It is fully certified to the ECE 22-06 standard, providing superior protection against rotational forces and high-velocity impacts.
Innovative Climate Control
Stay cool even on the hottest asphalt. The Y.100 features a large upper intake and an efficient chin vent. What sets it apart is the innovative air chamber located between the dual EPS liners; this system ensures that fresh air doesn’t just enter the helmet but circulates 360° around the rider’s head before being pulled out through the rear exhausts.
Intercom-Ready with Premium Audio
The Y.100 is engineered for the X-COM 3 ecosystem. The seamless integration means the intercom doesn’t “stick out” from the shell, preserving the helmet’s quiet aerodynamics. For the ultimate experience, the X-COM 3 PRO variant brings world-class Harman Kardon sound directly into your ears, turning every ride into a high-fidelity experience.
Key Technical Features:
Pinlock Included: Comes with a Pinlock 70 Antifog lens to ensure clear vision in humid or cold conditions.
Action Camera Ready: Includes a removable side-mount support for action cameras, perfect for vlogging or safety recording.
Aerodynamic Spoiler: The rear spoiler helps stabilize the helmet at highway speeds, reducing neck strain.
Dual Shell Sizes: Available in two shell sizes (XS–M and L–XXL) to ensure a proportional fit and lower weight for smaller head sizes.
Interior Comfort: Plush, sweat-wicking liners that are fully removable and washable.
Why Choose the Y.100 Core?
For riders who don’t need wild graphics and want to save money for their next trip, the Nexx Y.100 Core Helmet series provides the exact same shell and safety tech as the more expensive graphic models. It’s the “smart buyer’s” choice in the Nexx 2025 catalog.
