What truly sets the R12 apart are its thoughtful features and the technology of its time. The expanding drum brakes, both front and rear, provide dependable stopping power, while the kick starter adds to its classic charm. The bike's design elements, such as its elegant lines and chrome accents, reflect the Art Deco influence of the 1930s, making the R12 a visual masterpiece as well as a mechanical one.
