Suzuki's midsize dual-purpose single, the DR 350S, was a street-legal version of the dirt-focused DR line with lights, a steel fuel tank and road equipment added. It used a four-valve SOHC single with dry sump lubrication and long, adjustable suspension. Period magazine testing rated it excellent off road but limited on the street by low power, comfort and a small tank.
