British Motorcycles and Royal Mail are riding together now. Royal Mail selects a theme every year to launch a special Stamp Calendar and this year the theme is British Motorcycles. For most of the 20th century Britain was a world leader in motorcycle development and manufacture. Royal Mails celebration of the UK motorcycle industry is illustrated with a wide range of manufacturers, and the machine on each stamp represents a major leap forward in design at the time.

The Royal Enfield 1914 model which was a small engined motor bicycle has been showcased on a 68p stamp. The other motorcycles to be alongside are the 1930 Brough Superior - bespoke luxury motorcycle, 1937 Triumph Speed Twin - two cylinder innovation, 1949 Vincent Black Shadow - fastest standard motorcycle, 1969 BSA Rocket 3 - only 3 cylinder superbike and the 1991 Norton F1 - road version of the race winner.
