HJC i80 Velly MC4SF Bottom Chin Vent - Restore low front ventilation

On your HJC i80 Velly MC4SF, the lower chinstrap ventilation is a small part that has a real influence on comfort at the front of the helmet. When it's damaged, broken or missing, air doesn't circulate as well towards the bottom of the visor and your face. This can lead to fogging of the lower part of the screen or a feeling of stagnant air, especially on hot, humid days or long journeys. At iCasque, we offer you the original HJC bottom vent, designed to restore ventilation while respecting the aesthetics of the Velly MC4SF graphics.

The part is very easy to replace: it clips into place in seconds, without tools, for rapid restoration. Visually, it perfectly matches the Velly MC4SF style, guaranteeing a clean, even finish on your i80's chinstrap. A functional lower front vent helps direct air down the visor, helping to reduce fogging and improve your comfort, whether on daily commutes or long jaunts.

At iCasque, we prefer to repair rather than replace. A spare part like this can extend the life of your helmet without compromising on functionality or style.

Why choose it?

1. Technical Advantage : Restores downward airflow for smoother internal circulation and better fogging of the lower part of the screen.
2. Style/Practical Advantage: Matching Velly MC4SF graphics for harmonious visual integration with the helmet.
3. Compatibility Advantage: Genuine HJC part designed for the i80 - installs without adjustment.

Easy care

Regular cleaning with a soft, slightly damp cloth removes dust and debris. Avoid aggressive products or solvents that could alter the material or decoration. If you store the part outside the helmet, keep it in a clean, dry place to prevent dust accumulation.
