This limited edition helmet pays homage to the 1930s — the golden era for Royal Enfield, the undoubted high point being the 1932 launch of the world-famous Bullet. The 500 Bullet, with its 4-valve cylinder head, was capable of 100mph when race tuned yet functioned perfectly as a go-to-work mount. For almost 90 years the Bullet has been the first and last word in traditional motorcycle design and is the longest running production model by any manufacturer.
