HJC F100 BIOS Rotational Modular Motorcycle Helmet

The HJC F100 BIOS Rotational Modular Motorcycle Helmet is a advanced flip-up helmet designed for touring, featuring a lightweight shell and a chin bar that rotates all the way to the back of the helmet.

Here is a summary of its key features and specifications:

Core Technology and Safety

• Rotational Modular Design: The defining feature is the chin bar’s innovative 180° rotation system, which allows the helmet to convert from a full-face to an open-face (jet) configuration where the chin bar is secured at the back. This provides maximum versatility.
• Shell Material (AFC): Constructed from an Advanced Fiberglass Composite (AFC) shell, which is lightweight yet highly impact-resistant. This makes it lighter than many other rotational modular helmets. It comes in 3 different shell sizes.
• Homologation: It has ECE 22.06 P/J Dual Homologation, meaning it is legally approved to be ridden safely in both the closed (Full-Face ‘P’) and opened (Jet ‘J’) positions.
• Retention System: It uses a Micrometric Buckle (ratchet closure) for secure and quick fastening that is easy to operate even with gloves on.

Visor and Sun Shield

• Main Visor: The HJ-45 visor is Pinlock-ready, anti-scratch coated, and offers 99% UV-A & B protection. A Pinlock lens is typically included in the box.
• Integrated Sun Shield: Features an installed Dark Smoke sun shield (HJ-V12) with a newly designed adjustable mechanism that allows the sun visor to extend by 8mm for improved sun protection.
• Visor Size: There are two different visor sizes (HJ-45A and HJ-45B) depending on the helmet size (A for XS-M, B for L-2XL).

Comfort and Ventilation

• Ventilation: It utilizes the “ACS” Advanced Channeling Ventilation System, which provides full front-to-back airflow to flush heat and humidity out of the helmet. This includes 2 intake ports and 3 exhaust ports.
• Interior: The interior parts are moisture-wicking, breathable, and dry.
• Fit: It features 3D contour cheek pads for enhanced comfort and a secure fit.
• Removable/Washable: The crown and cheek pads are fully removable and washable for easy maintenance.
• Glasses Grooves: Integrated grooves are specifically designed to accommodate riders who wear eyeglasses.

Included Accessories

The helmet typically comes standard with:

• Pinlock lens
