Suzuki DR800S

The Suzuki DR800S, also called the DR Big 800S, is a 779 cc single-cylinder dual-sport motorcycle made by Suzuki from 1990 to 1999. Its single-cylinder four-stroke engine is air and oil cooled by the Suzuki Advanced Cooling System and delivers 54 HP at 6,600 rpm and a maximum torque of 59 Nm at 5,400 rpm. At launch it was the production bike with the largest single-cylinder engine, and it stayed so afterwards. Two Mikuni carburettors feed an SOHC four-valve head with twin spark ignition and double countershafts to reduce vibration, driving through a five-speed gearbox and chain in a steel double cradle frame.
