How to measure: Wrap a soft tape around the widest part of the head, approximately one inch above the eyebrows and over the largest portion at the back. A new helmet should feel evenly snug without painful pressure points.
Rider-informed FAQs
How do I choose the correct size?
Measure the widest part of the head above the eyebrows and compare with FLY’s street-helmet chart. A new helmet should feel evenly snug without isolated pressure points; it should not rotate independently of the head.
Can I install a communicator?
The listed speaker pockets are intended to simplify Bluetooth or intercom installation. Confirm speaker thickness and microphone routing for your specific system.
How should I manage fogging?
Use the vents and breath deflector as designed, keep the shield clean, and use the compatible anti-fog or Pinlock option only when the specifications identify one.
