Carbon fiber motorcycle helmets are some of the top performing crash helmets available - often performing well in SHARP safety tests and being lighter than polycarbonate models. Unfortunately, however, they tend to be more costly. Schuberth C5 modular carbon helmets feature an innovative feature to allow riders to quickly and safely tuck chin bars up out of the way when not racing, enabling riders to sip water or engage with riding companions without taking off their helmet.
