HJC Size Chart

HJC Size Chart

HJC offers motorcycle helmets and bicycle helmets with partly different size ranges. The categories are therefore listed separately. Individual models may differ from the general reference chart; product-specific sizing always takes priority.

Motorcycle helmets – general HJC reference chart

Measure the head circumference with a flexible measuring tape around the head. For motorcycle helmets, HJC recommends measuring approximately 2.5 cm above the eyebrows.

Safety note: A size chart is a reference only. A helmet must fit firmly and evenly around the head, must not move out of position and should not create problematic pressure points. HJC warns that wearing the wrong helmet size can increase the risk of injury. Always try the helmet on and follow the product-specific fitting and safety instructions.
