Wrap a tape measure around your head approximately one inch (2.5 cm) above your eyebrows. Compare this measurement to the official HJC Size Chart. If your measurement falls between two sizes, try the larger size first. A correct fit should be snug but not painful, and the helmet should not move freely on your head.
It is generally recommended to avoid applying paint, stickers, petrol, or other solvents to the helmet, as these substances can damage the shell or protective foam integrity, potentially reducing safety.
For systems like the 11B or 21B, typically hold the center or power button for 10 seconds to enter configuration mode, or use the Smart Intercom Pairing (SIP) feature via the SMART HJC App to scan QR codes for quick pairing.
HJC helmets are designed for a single impact. If dropped, the protective foam or shell may sustain non-visible damage. For your safety, the helmet should be replaced immediately after any significant impact.
Firmware updates and the HJC Device Manager software can be found on the official SMART HJC website (www.smarthjc.com).
