To make a helmet without foam rubber, you can consider using alternative materials such as hard plastic, fiberglass, or carbon fiber. These materials can provide impact protection similar to foam rubber. You can shape and mold these materials to create a helmet that fits securely and comfortably. Additionally, you can line the inside of the helmet with softer materials like fabric or padding for added comfort. **

The choice between a roller helmet and a motocross helmet depends on the activity you will be engaging in. If you are rollerblading or skateboarding, a roller helmet would be more suitable as it is designed for those specific sports and provides adequate protection for impacts common in those activities. On the other hand, if you are riding a motorcycle or participating in motocross, a motocross helmet would be the better option as it offers additional protection for higher speeds and more intense impacts. It is important to choose the helmet that is designed for the specific activity you will be doing to ensure maximum safety. **

The choice between a ski helmet and a riding helmet depends on the activity you are participating in. If you are skiing, a ski helmet is designed to provide protection against the specific risks associated with skiing, such as collisions with other skiers or obstacles. On the other hand, if you are horseback riding, a riding helmet is designed to protect against the risks associated with horseback riding, such as falls from a horse. It's important to choose the appropriate helmet for the specific activity to ensure the best protection. **

Helmet visors are typically designed to fit specific models of motorcycle helmets. It is important to check the manufacturer's specifications to ensure compatibility. Different helmet brands and models may have unique visor attachment mechanisms, so it is recommended to purchase a visor that is specifically designed for your helmet to ensure a proper fit and secure attachment. Using a visor that is not designed for your helmet may compromise safety and functionality. **

The choice between a full-face helmet and a motocross helmet depends on the type of riding you will be doing. A full-face helmet provides more overall protection as it covers the entire head and face, making it ideal for street riding and high-speed activities. On the other hand, a motocross helmet is designed for off-road riding and provides better ventilation and visibility, with a sun peak to block the sun and roost. Ultimately, the best helmet for you will depend on your specific riding needs and preferences. **

A cross-enduro helmet is better suited for activities such as off-road biking, motocross, and other high-speed, high-impact sports. It offers more protection for the head, face, and neck, and is designed to withstand the forces of a motorized vehicle crash. On the other hand, a bicycle helmet is better suited for lower-impact activities such as cycling, skateboarding, and rollerblading. It is lighter and more aerodynamic, providing adequate protection for these types of activities. Ultimately, the choice of helmet depends on the specific activity and the level of protection required. **

If the helmet does not fit in the helmet compartment, it may be too large or the compartment may be too small. It is important to check the dimensions of both the helmet and the compartment to determine the issue. If the helmet is too large, consider storing it in a different location or using a helmet bag for protection. If the compartment is too small, you may need to find an alternative storage solution for the helmet. **
