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 mounts 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,[1] remaining so even after.[2]
The engine is fed by two Mikuni carburettors assisted by a "twin spark" transistor electronic double ignition system with two spark plugs, having SOHC distribution with 4 chain-operated valves per cylinder 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.
