5. Setup
5.1 Adjusting/Removing the Visor
The visor can be adjusted to two positions or completely removed. To adjust, simply twist the screw on top with your fingers and shift it to the desired hole. To remove the visor entirely, unscrew both side screws and the top screw, then detach the visor. Remember to use the provided rubber plugs to cover the empty screw holes when the visor is removed to prevent water entry.
5.2 Removing/Installing Interior Padding
The cheek pads and comfort liner are designed for easy removal and installation. They typically clip in and out. Gently unclip the padding from its attachment points within the helmet. When reinstalling, align the clips and press firmly until they snap into place, ensuring a secure fit.
6. Operating Your Helmet
6.1 Shield Operation
The integrated clear shield moves smoothly into four different positions. This allows for quick adjustments for airflow, such as cracking it open slightly when sitting in traffic, or fully closing it for protection from elements. The shield is designed to be easily operated even with gloves on.
6.2 Ventilation Control
The main mouthpiece vent can be easily opened or closed to regulate airflow based on temperature and riding conditions. The helmet's overall ventilation system is designed to keep your head comfortable across a wide range of temperatures.
6.3 Goggle and Glasses Compatibility
The MX-9 Adventure helmet is designed to accommodate most goggles comfortably. The shield can close over the top of goggle elastic bands, eliminating the need to constantly remove and re-don goggles. It is also comfortable for riders who wear prescription glasses or sunglasses, with ample space to prevent rubbing or discomfort.
7. Maintenance
7.1 Cleaning the Shield
The shield can be easily popped off for cleaning. For the anti-fog interior, use only gentle soap and water. Avoid harsh chemicals or abrasive materials that could damage the coating. For the exterior, use a soft cloth and mild soap and water. Rinse thoroughly and air dry.
7.2 Washing the Liner and Pads
The removable comfort liner and cheek pads can be machine washed. It is recommended to use a gentle cycle with mild detergent and air dry them completely before reinstalling. Regular washing helps maintain hygiene and extends the life of the interior components.
8. Troubleshooting
8.1 Wind Noise at High Speeds
Some riders may experience wind noise at highway speeds. This is common with many helmets. Wearing earplugs or Bluetooth earbuds can help mitigate this issue. The helmet's design aims to minimize noise, but individual experiences may vary based on motorcycle type and riding posture.
8.2 Shield Fogging
The integrated shield features NutraFog II technology to prevent fogging. If fogging occurs, ensure the shield is clean and free of residue. Opening the shield to one of its cracked positions can also increase airflow and reduce fogging, especially when stationary or at low speeds.
