No, motorcycle riders do not always cover their helmets with a cloth. While some riders choose to cover their helmets with a cloth or a helmet cover for various reasons, it is not a universal practice.
Covering a helmet with a cloth or a helmet cover can serve a few purposes:
Protection: A cloth cover can help protect the helmet from dust, dirt, scratches, and other minor damages when the motorcycle is parked or stored. It can help keep the helmet clean and in good condition.
Sun Protection: Exposing the helmet to direct sunlight for extended periods can lead to color fading, degradation of materials, and potential deterioration of the helmet's protective capabilities. A cloth cover can provide some level of sun protection when the helmet is not in use.
Personalization: Some riders use helmet covers as a means of personalizing their helmets. The covers come in various designs, colors, and patterns, allowing riders to express their individuality and style.
The helmet should still be able to function properly and provide the necessary protection in case of an accident.
Ultimately, the decision to cover a helmet with a cloth or not is a personal choice made by individual riders based on their preferences, the specific circumstances, and their desired level of helmet protection and personalization.
