Yamaha has unveiled the 2015 model SR400 vintage cafe racer ahead of its return into the U.S. market next year. The bike features a 399cc air-cooled 4-stroke single-cylinder engine and a slim twin-shock chassis, while the classic design takes inspiration from the S400. Aesthetically the bike boasts a clean look with slick silver hardware, navy and black styling. Expected to sell for $5,990 USD, the SR400 hits dealers this May.
