HJC PINLOCK-INSERT
(Product No.: BB-107H90-0.799)
Pinlock anti-fog insert lens for a compatible Pinlock-ready HJC visor. Version: according to the product variant.
The moisture-absorbing surface captures water molecules. At the same time, the airtight silicone seal creates an insulating air chamber between the visor and insert lens, reducing condensation.

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.
