The Yamaha XJ 900 was a motorcycle produced by Yamaha since 1983 as a development of the original Yamaha XJ 650 model, which was the base model of the XJ series. The bike had at its core an 853cc four-cylinder engine.
In 1984, Yamaha released a revised version that featured a displacement increase to 891cc. In addition to its slightly larger engine, the bike packed a more conventional fork on the front and a belly pan as standard equipment.
In 1985, the Japanese motorcycle manufacturer launched the Yamaha XJ 900, a bike fitted with standard features, such as a rectangular headlight integrated into an upper fairing, a small windscreen, a one-piece dual seat with a passenger grab handle, a dual exhaust system with a silencer on each side, and three-spoke lightweight wheels.
The bike packed a 37 mm telescopic fork and two 254 mm discs with dual-piston calipers on the front and twin side-mounted shock absorbers on the rear with a 254 mm disc tied to a single-piston caliper, offering optimum suspension performance and stopping power.
In the performance department, the 1985 Yamaha XJ 900 had installed an an891cc four-stroke four-cylinder air-cooled engine underneath its fuel tank, delivering 97 hp with a peak force at 9,000 rpm and 81 Nm (60 lb-ft) torque at 7,000 rpm.
The power produced by the engine was transferred to a five-speed manual transmission and sent to the rear end through a low-maintenance final shaft drive.
