2. WEARING THE HELMET
2.1 How to Wear The Helmet
For proper use, the helmet must sit level on the head and low on the
forehead. The Sena helmet uses a simple, quick-release buckle system
that, once adjusted, can be buckled and unbuckled without changing
the adjustment. For proper use, the straps must be tight and evenly
tensioned.
To properly wear your helmet:
1. Position the helmet on your head with the front covering your
forehead. If the helmet is tipped back and is not covering your
forehead then the helmet is not in the proper position.
2. Position the strap adjuster centered, just below your ears.
WARNING: Always wear the helmet in the proper position on
your head with the front of the helmet covering your forehead for
maximum protection. Never wear the helmet tipped back as the
helmet will be in the improper position causing your forehead to be
exposed. All fitment adjustments need to be made with the helmet
in the proper position.
3. Position the helmet low on your forehead with the buckle under the
chin and back against the throat. The straps should fit comfortably
around both ears.
