Product Details
The HJC V31 Byron MC1SF Red is an ECE 22.06 retro open-face motorcycle helmet featuring HJC's Byron MC1SF Red graphic. Its Advanced Fibreglass Composite shell, integrated smoke sun shield and carefully finished interior suit urban riding, commuting and relaxed road use.
Who It's For
This helmet is aimed at riders who want classic open-face styling, a broad view and convenient glare protection. It is well suited to city journeys, commuting and relaxed road riding. As an open-face design, it provides less facial and weather coverage than a full-face helmet.
