Scorpion Exo 391 Clutter Black/Cham

The Scorpion Exo 391 is a full-face motorcycle helmet in Black/Cham, made with lightweight polycarbonate construction. Its aero-tuned design was developed using a wind tunnel, with the aim of increasing comfort and reducing noise alongside the chin cover.

The rear spoiler is aero-tuned to reduce lift and is designed to work with the ventilation system to create a vacuum and maximise airflow. The helmet has a multi-point ventilation system and a removable inner lining.

• The visor is prepared for an optional Pinlock anti-fog insert.
• A locking visor uses a quick-release mechanism.
• The helmet has a quick-release micro buckle strap.
• All motorcycle helmets are supplied with a clear visor. Tinted visors are for illustration purposes only and are not for UK road use.

The size guide gives XS as 53–54, S as 55–56, M as 57–58, L as 59–60, XL as 61–62 and 2XL as 63–64. Scorpion helmets generally size up small. Motorcycle helmets are designed for a close, comfortable fit and can change size with use. The size guide is only a guide and cannot determine an exact size; fitment advice and trying the helmet before purchasing are recommended.
