The Yamaha FJ1100 and FJ1200 are sport touring motorcycles that were produced by Yamaha between 1984 and 1996.

Yamaha released the FJ1100 for model years 1984 and 1985. This class is characterised by retaining sportiness while integrating more street-friendly riding characteristics, including good manoeuvrability as well as long distance comfort, such as a more upright seating configuration designed to reduce back strain and a large fairing to reduce fatigue from wind resistance. Emphasis is placed on a balance of utility and sport, rather than pure performance orientation. The machine was noticeably narrower than many contemporaries, Yamaha achieved this by placing the alternator behind the cylinders instead of the more normal position on the end of the crankshaft.

In 1986 Yamaha decided to upgrade the FJ1100 by increasing the engine displacement slightly and adding upgraded suspension and other components. The result was the FJ1200. The peak power output was raised slightly to 130 bhp (97 kW) from the FJ1100s 125 bhp (93 kW), the FJ1200 had more low- to mid-range torque. The FJ1200 was produced in three main successive versions (1TX, 3CV and 3XW) each updated version benefiting from improvements to bodywork, front and rear suspension components, and the addition of an optional ABS-equipped version (FJ1200A) from 1991 until 1996, when Yamaha discontinued the FJ1200 in the United Kingdom. The model was discontinued in the United States in 1993. Market competitors during its production years included the BMW K100RS, Suzuki's 1100 Katana and Kawasaki's Ninja ZX-10.

The FJ1200 uses a four cylinder in-line layout and is air-cooled. Sixteen valves are operated by a chain-driven double overhead camshaft; valve clearances are adjusted using shims. The four constant-velocity carburettors are mounted in a bank behind the cylinders and feed each cylinder through short intake manifolds. Four exhaust downpipes join a box below the engine where the gases are split to exit through two silencers (mufflers). The crankshaft is geared directly to the clutch, no counter balancer shaft is used. Starting is by electric starter only. Lubrication is wet sump using a trochoid pump; an oil radiator assists with cooling. Both the FJ1100 and FJ1200 were fitted with an additional fuel vapour recovery system to comply with California emission regulations.
