The Alpinestars Supertech M10 helmet is engineered to provide advanced protection and performance for riders.

2. Safety Information
WARNING: Failure to follow these instructions may result in serious injury or death.
- Always wear a helmet that fits correctly and is securely fastened.

- Never modify your helmet. Any modifications, including painting, attaching accessories, or altering internal components, can reduce its protective capacity.
- Do not expose the helmet to petroleum products, cleaning agents, paints, adhesives, or other solvents, as these can damage the helmet materials without visible signs.
- Legal Disclaimer: This helmet is DOT approved and FMVSS 218 certified for legal on-road motorcycle use in the United States. Ensure your helmet meets local safety standards for your region.

3. Setup and Fitting
Proper helmet fit is crucial for safety and comfort. Follow these steps to ensure your helmet is correctly set up.
3.1 Head Measurement
To determine your correct helmet size, measure your head circumference just above your eyebrows and ears. Refer to the size guide below.

A table provides corresponding head circumference measurements in centimeters and inches for various helmet sizes (XS, S, M, L, XL, XXL).
3.2 Visor Installation and Adjustment
The Supertech M10 features a unique, patented visor release system for easy installation and adjustment. Consult the detailed instructions provided with your helmet for specific steps on attaching and positioning the visor securely.
3.3 A-Head Fitting System
The patented A-Head fitting system allows for height and angle adjustment, ensuring a personalized and secure fit. Adjust the internal padding and straps to achieve a snug fit that does not cause pressure points but prevents excessive movement.

5. Maintenance and Care
Proper maintenance extends the life and effectiveness of your helmet.
- Cleaning the Shell: Use a soft cloth dampened with mild soap and water. Avoid harsh chemicals or abrasive cleaners.
- Cleaning the Interior: Removable liners can often be hand-washed with mild soap and air-dried. Refer to specific care labels if available.
- Storage: Store your helmet in a cool, dry place, away from direct sunlight and extreme temperatures. Do not store it near heat sources or chemicals.
- Inspection: Regularly inspect the helmet for any signs of damage, such as cracks in the shell, frayed straps, or worn padding. Replace the helmet if any damage is found or after any significant impact.
6. Troubleshooting
If you encounter issues with your helmet, consider the following:
- Poor Fit: Re-check your head measurement against the size guide. Ensure the A-Head fitting system is adjusted correctly. If the helmet is too loose or too tight, it may be the wrong size.
- Discomfort/Pressure Points: Adjust the internal padding. If discomfort persists, the helmet shape may not be compatible with your head shape, or the size may be incorrect.
- Visor Issues: Ensure the visor is correctly seated in its mechanism. Refer to the visor installation instructions.
- Unusual Noise: Check for loose components or improperly sealed vents.
