The Suzuki DR800S is a single-cylinder dual-sport motorcycle made by Suzuki from 1990 to 1999.
History and development
The DR800S (also called DR Big 800S or DR800S Big) is a motorcycle produced by the Japanese motorcycle manufacturer Suzuki. The bike is powered by a single-cylinder four-stroke engine with an air/oil-cooled SACS (Suzuki Advanced Cooling System) cooling system available in the single displacement of 779 cm3, which delivers 54 HP at 6600 rpm and a maximum torque of 59 Nm at 5400 rpm.
At the time of launch, it was the production bike with the largest single-cylinder architecture engine, remaining so even after.
The engine is fed by two Mikuni carburettors assisted by a "twin spark" transistor electronic double ignition system with two spark plugs, having a timing chain-operated SOHC with 4 valves and equipped with double countershafts to reduce the strong vibrations typical of single-cylinder engines, with wet sump lubrication.
Primary transmission is via gears and a mechanically operated wet multi-plate clutch, assisted by a five-speed gearbox. Power is transmitted to the rear wheel via chain.
The frame is of the double cradle type in steel with a square section.
