Triumph X Arai Quantic Motorcycle Helmet

The Triumph X Arai Quantic is a full-face motorcycle helmet with a new Quantic ventilation system. Its bespoke top vent system helps flush heat and humidity out of the helmet.

The helmet uses Peripherally Belted e-Complex Laminate Construction and has a one-piece rear spoiler and a Glace off safety design. A Pinlock insert is included.

The size guide gives S as 55–56, M as 57–58, L as 59–60 and XL as 61–62. Motorcycle helmets are designed for a close, comfortable fit and can change size with use. The size guide cannot determine an exact fit; fitment advice and trying the helmet are recommended.
