1955

YA-1 1955 (1955)
This was Yamaha’s first motorcycle. At a time when motorcycle design was dominated by imposing all-black styling, the YA-1 with its simple form and modern chestnut red coloring, quickly became popularly known by the nickname “Aka-tombo” (the Red Dragonfly). What’s more, it immediately demonstrated its high performance by winning the 3rd Mt. Fuji Ascent Race in July of 1955, and then swept the top places in the ultra-light class of the 1st Asama Highlands Race of the All Japan Endurance Championships. In an era when the national average starting salary of a male college graduate was 10,780 yen, this model, priced at 138,000 yen, was a coveted extravagance beyond the reach of most users.
‘Overall length x width x height: 1,980mm x 660mm x 925mm
Weight: 94kg
Engine-type: Air-cooled 2-stroke 1-cylinder 123cc
Maximum power output: 5.6ps/5,000rpm
Maximum torque: 0.96kg-m/3,300rpm

1956

YC-1 1956 (1956)
A deluxe version of the YA-1, this model immediately drew public attention when it appeared at the Tokyo Motor Show held in Hibiya Park in April of 1956. With a grayish-brown finish, taking its image from the wet pavement of the Champs-Elysees, this model represented a high-level marriage of design and function with features like the first domestic-made monobloc carburetor. This immediately boosted the brand image of Yamaha, a company that was still at the time, a latecomer to the Japanese motorcycle industry.
‘Overall length x width x height: 2,040mm x 660mm x 940mm
Weight: 118kg
Engine-type: Air-cooled 2-stroke1-cylinder 174cc
Maximum power output: 10.3ps/5,500rpm
Maximum torque: 1.6kg-m/3,400rpm

1957

YD-1 1957 (1957)
This is a model born out of a pursuit of design originality. In the development as well, the design elements proceeded the engineering. Taking as its key words “A 250cc for the Japanese,” it was given a compact and easy to ride body size that fit the Japanese physique. What’s more, it embodied a “Dynamic design” that gave the impression of powerful dynamism in any situation. It also mounted Yamaha’s first 2-cylinder engine. In a Japanese market dominated at the time by utility models, the YD-1 brought a new image of sports performance.
‘Overall length x width x height: 1,935mm x 705mm x 935mm
Weight: 140kg
Engine-type: Air-cooled 2-stroke 2-cylinder 247cc
Maximum power output: 14.7ps/6,000rpm
Maximum torque: 1.9kg-m/4,000rpm

1959

YDS-1 1959 (1959)
Further developing on the sporty performance of the YD-1, this new model mounted a 20hp engine on a steel-pipe cradle frame to achieve unprecedented running performance. Features like the first domestic-made 5-speed transmission and combination type instrument panel with engine tachometer caught the imagination of sports riders, who quickly nicknamed it “Japan’s first sports model.”
‘Overall length x width x height: 1,990mm x 615mm x 950mm
Weight: 138kg
Engine-type: Air-cooled 2-stroke 2-cylinder 246cc
Maximum power output: 20ps/7,500rpm
Maximum torque: 1.9kg-m/6,000rpm

1963

YG-1 1963 (1963)
Mounting a rotary disk valve engine on a backbone type monocoque frame and boasting a number of features like waterproof brakes, a headlight nacelle and a megaphone type muffler, the YG-1 quickly became a popular model and a big hit in sales. With increased engine reliability through improved cooling performance and greater serviceability in the air filter, carburetor and clutch, this model represented a great combination of sportiness and utility.
‘Overall length x width x height: 1,815mm x 625mm x 960mm
Weight: 82kg
Engine-type: Air-cooled Rotary disk valve 1-cylinder 75cc
Maximum power output: 6.5ps/7,000rpm
Maximum torque: 0.7kg-m/5,000rpm

1965

AT90 1965 (1965)
This model appeared as a dual-purpose bike that combined business utility with sportiness. Mounting a small-displacement high-rpm type 90cc twin cylinder engine known as the “jet twin,” this model became especially popular among sports-minded riders. The “AT” in its name came from its Autolube lubrication system. This forced lubrication mechanism achieved both high performance and low fuel consumption as well as good utility.
‘Overall length x width x height: 1,820mm x 765mm x 1,007mm
Weight: 99kg
Engine-type: Air-cooled Piston valve 2-cylinder 89cc
Maximum power output: 8.2ps/8,000rpm
Maximum torque: 0.75kg-m/7,500rpm

1966

YDS-3 1966 (1966)
Yamaha’s YDS series had evolved steadily from the YDS-1 introduced in 1959 through the YDS-2 of ’62 and then this YDS-3. One of the foremost Japanese sports models, it also won great popularity in the USA. As the first 2-cylinder model to adopt the Autolube system, it achieved unchallenged reliability and high-speed durability. Also adopting features like a 3-step adjustable shock absorber, this model represented a high-level marriage of engine performance, running performance and utility.
‘Overall length x width x height: 2,005mm x 780mm x 1,050mm
Weight: 159kg
Engine-type: Air-cooled Piston valve 2-cylinder 246cc
Maximum power output: 26ps/8,000rpm
Maximum torque: 2.5kg-m/7,500rpm

1968

DT-1 1968 (1968)
Winning an unprecedented following from the time of its release, this DT-1 started a worldwide boom in trail bikes. Before the appearance of the DT-1, off-road bikes had been primarily “scrambler” type bikes adapted from on-road models. By contrast, this model was the embodiment of a machine to take you “beyond where the roads end.” Packed full of technologies and features expressly for off-road riding, like a Ceriani type front fork with the longest stroke of any Japanese-made unit at the time, Autolube, a 5-port piston valve engine, wide-radius block-pattern tires and an engine guard, this model created the new genre known as “trail bikes.”
‘Overall length x width x height: 2,060mm x 890mm x 1,130mm
Weight: 112kg
Engine-type: Air-cooled Piston valve 1-cylinder 246cc
Maximum power output: 18.5ps/6,000rpm
Maximum torque: 2.32kg-m/5,000rpm
