The Yamaha TDM was a sport-touring motorcycle manufactured by Yamaha from 1991 as a replacement for the XTZ 750 Super Tenere and continued production until 2001, when it was replaced by the Yamaha TDM 900.
The Yamaha TDM was the first Yamaha road-oriented adventure sports motorcycle. Still, it was not intended as an off-road machine, although its long-travel suspension could cope with gravel trails. The bike was as comfortable and maneuverable as the later Ducati Multistrada.
In 1991, the Japanese motorcycle manufacturer launched the Yamaha TDM 850, a sport-touring machine powered by an 849cc DOHC parallel-twin engine mounted in a pressed steel frame.
The bike's appearance was characterized by its two round headlights and standard features, such as a half fairing with a small windscreen, a one-piece dual seat with passenger grab handles, a dual exhaust system with a silencer on each side, and three-spoke lightweight aluminum wheels.
Suspension-wise, the bike packed a 41 mm rebound and preload-adjustable telescopic fork on the front with 160 mm of travel and a preload and rebound-adjustable DeCarbon-type shock absorber on the rear with 140 mm of travel.
The 1991 Yamaha TDM 850 had installed an 849cc four-stroke parallel-twin liquid-cooled engine underneath its fuel tank, delivering an output power of 77 hp with maximum strength at 7,500 rpm and 76 Nm (56 lb-ft) torque at 6,000 rpm.
