How should I choose the correct HJC helmet size?

Measure your head circumference with a soft tape measure above your eyebrows. Compare the measurement to the HJC size chart for the specific model you're buying, as fit may vary between product lines.
Can I replace the visor or shield on my HJC helmet?

How do I clean my HJC helmet properly?

Use a mild soap and warm water for the shell. Interiors on most HJC models are removable and washable, but avoid harsh chemicals and do not use heat to dry the liners.
