3. Setup
3.1 Initial Inspection
Before first use, carefully inspect your helmet for any signs of damage from shipping. Check that the visor operates smoothly and the chin strap buckle functions correctly.
3.2 Visor Installation and Removal
The clear visor can be removed for cleaning or replacement. Consult the quick-release mechanism on the side plates of the helmet. Typically, a lever or button allows the visor to detach. Align the visor tabs with the helmet's slots and press firmly until it clicks into place.
3.3 Pinlock Insert Installation
Your helmet may include a Pinlock anti-fog insert. To install:
- Remove the clear visor from the helmet.
- Flex the visor slightly to flatten it.
- Align the Pinlock insert's silicone seal with the visor's inner surface, ensuring the pins fit into the designated holes.
- Press the insert firmly onto the pins, working from the center outwards, until the silicone seal creates a tight fit around the visor.
- Ensure there are no gaps between the Pinlock and the visor.
3.4 Adjusting Ventilation
The helmet features adjustable vents on the chin and top. Open or close these vents by sliding the respective mechanisms to control airflow. Fully open for maximum ventilation, closed for reduced airflow.
4. Operating Instructions
4.1 Clear Visor Operation
The clear visor can be opened to various positions or fully closed. Use the tab on the visor to lift or lower it. Ensure the visor is fully closed for maximum protection and to minimize wind noise at higher speeds.
4.2 Twin Shield System (Internal Sun Shield) Operation
The internal sun shield is operated by a lever located on the side of the helmet. Slide the lever forward to deploy the sun shield and backward to retract it. This system provides quick eye protection from glare without needing to change visors.
4.3 Ventilation System Use
Adjust the chin and top vents according to riding conditions. Opening the vents increases airflow, which can help with cooling and fog prevention. Closing them reduces airflow, useful in colder or wet conditions.

5. Maintenance and Care
5.1 Cleaning the Helmet Shell
Clean the helmet shell with a soft cloth, warm water, and mild soap. Avoid harsh chemicals, solvents, or abrasive cleaners, as these can damage the shell material and finish. Rinse thoroughly and air dry.
5.2 Cleaning the Visor and Sun Shield
Remove the visor and sun shield for cleaning. Use warm water and a soft cloth. For stubborn dirt or insects, soak a soft cloth in warm water and place it over the affected area for a few minutes before gently wiping. Do not use abrasive materials or chemical cleaners. Air dry or gently pat dry with a microfiber cloth.
5.3 Cleaning and Removing the Interior Liner
The interior comfort liner is removable and washable. Gently detach the liner components from the helmet. Hand wash with mild soap and warm water, or machine wash on a delicate cycle in a laundry bag. Air dry completely before re-installing. Ensure all components are dry to prevent mildew.
5.4 Storage
Store your helmet in a cool, dry place away from direct sunlight and extreme temperatures. Use the provided helmet bag to protect it from dust and scratches.
6. Troubleshooting
- Whistling Noise from Visor: If a whistling noise occurs when the clear visor is partially open, ensure it is either fully closed or opened to a stable detent position. Some visor positions may create aerodynamic noise.
- Sun Shield Not Functioning Smoothly: Check for any obstructions in the sun shield mechanism. Ensure the lever is clean and free of debris. If the issue persists, contact customer support.
- Visor Fogging: Ensure the Pinlock insert is correctly installed and sealed. If fogging still occurs, slightly open the clear visor to allow more airflow, or utilize the helmet's ventilation system.
- Helmet Feels Too Tight/Loose: Refer to the size guide in Section 5.2. If the fit is incorrect, consider trying a different size. Helmet liners can compress slightly over time, but a helmet should always feel snug.
