Motocross & Enduro Helmets Motocross and enduro helmets are specially designed for the demands of off-road biking. In addition to the fit, good ventilation is extremely important. Helmets designed specifically for motocross have no visor (you also need to order motocross goggles), while enduro helmets can be worn with either a visor or protective goggles. All motocross and enduro helmets in the Louis range meet the safety requirements of the current test standard ECE 22.05. If you're in any doubt, you can order two different sizes from Louis online and try them out. Louis will take back any item that does not fit or which you do not like.
