The Yamaha RD 350F was a sports motorcycle made by Yamaha from 1985 to 1986. It was a small-displacement motorcycle with the Yamaha Power Valve System (YPVS) and dressed in a full fairing, as its name says.
In 1984, the Japanese motorcycle manufacturer launched the Yamaha RD 350F, a modern and street-legal sports motorcycle, but also the last two-stroke powered machine sold in the American market.
In the visual department, the bike was characterized by a full fairing with an integrated rectangular headlight, a medium-sized windscreen, a one-piece dual seat with a passenger grab handle, a dual exhaust system with a silencer mounted on each side, and three double-spoke aluminum wheels.
The bike was built around a double cradle steel frame with a 35 mm air-assisted telescopic fork on the front, offering 140 mm of travel, and a five-way adjustable shock absorber on the rear, delivering 100 mm of travel.
The bike's wheels were fitted with two 260 mm discs with dual-piston calipers on the front and a 260 mm disc tied to a single-piston caliper on the rear, providing optimum stopping power.
As for the power figures, the 1984 Yamaha RD 350F had its soul brought to life by a 347cc two-stroke parallel-twin liquid-cooled engine, boasting 59 hp with a peak force at 9,000 rpm and 41 Nm (40 lb-ft) torque at 8,000 rpm.
