Why should you replace a helmet every two to four years?

Replacing a helmet every two to four years is crucial because its protective qualities can diminish over time due to various factors. Helmets are designed to absorb impact and protect the head during accidents. However, the materials used in helmet construction, such as foam liners and outer shells, can degrade due to exposure to sunlight, temperature changes, and general wear and tear. Over time, this degradation may reduce the helmet's effectiveness in protecting against impacts, even if there are no visible signs of damage.

Additionally, advancements in helmet technology can lead to improved safety features, which older models may lack. This means that even if an older helmet appears to be in good condition, it may not provide the same level of protection as newer designs. Regularly replacing your helmet ensures that you are using one that meets the latest safety standards and offers optimal protection for your head while riding an ATV.
