Motorcycle helmets come in all shapes and sizes, and are meant to satisfy a variety of applications. While there's absolutely nothing wrong with wearing an ultra-light, ultra-expensive carbon-fiber race helmet when riding your scooter on the way to work, there's no denying that it's a bit overkill and downright inconvenient. This is why more comfortable, relaxed helmet options such as open-face jet helmets are popular.
Sure, these types of helmets don't offer as much protection as your standard full-face lid, but it's understood that the speeds you'll be going within the confines of the city will be much lower than that of the highway or open road. This is especially true in Europe, wherein scooters are incredibly popular means of transport, and most city centers have speed limits no greater than 30 kilometers per hour (19 miles per hour).
