Yamaha Motor Company

Yamaha Corporation (originally known as Nippon Gakki Co.) was founded by Torakusu Yamaha in 1887 to manufacture reed organs and pianos and became the largest Japanese manufacturer of musical instruments in the early 20th Century. Yamaha was contracted to manufacture wooden and (later) metal airplane propellers by the Japanese government during World War II. The company struggled in the aftermath of the war, and in the early 1950s, chairman Genichi Kawakami decided to repurpose its underutilized war-time facilities to manufacture small motorcycles for leisure use.[6]

The motorcycle division of Yamaha was spun off in 1955, being incorporated on 1 July 1955 in Japan,[7] and was headed by Genichi Kawakami. Yamaha's initial product was a 125 cc (7.6 cu in) two-cycle, single cylinder motorcycle, the YA-1, which was a copy of the German DKW RT 125. The YA-1 was a competitive success at racing from the beginning, winning not only the 125cc class in the Mt. Fuji Ascent, but also sweeping the podium with first, second and third place in the All Japan Autobike Endurance Road Race that same year.[8] Early success in racing set the tone for Yamaha, as competition in many varieties of motorcycle racing has been a key endeavor of the company throughout its history, often fueled by a strong rivalry with Honda, Suzuki, Kawasaki and other Japanese manufacturers. Yamaha began competing internationally in 1956 when they entered the Catalina Grand Prix, again with the YA-1, at which they placed sixth. The YA-1 was followed by the YA-2 of 1957, another 125cc two stroke, but with significantly improved frame and suspension.[9] The YD-1 of 1957 was a 250cc two-stroke twin cylinder motorcycle, resembling the YA-2, but with a larger and more powerful motor. A performance version of this bike, the YDS-1 housed the 250cc two-stroke twin in a double downtube cradle frame and offered the first five-speed transmission in a Japanese motorcycle.[10] This period also saw Yamaha offer its first outboard marine engine.

By 1963 Yamaha's dedication to both the two-stroke engine and racing paid off with their first victory in international competition, at the Belgium GP, where they won the 250cc class. Success in sales was even more impressive, and Yamaha set up the first of its international subsidiaries in this period beginning with Thailand in 1964, and the Netherlands in 1968. 1965 saw the release of a 305cc two-stroke twin, the flagship of the company's lineup. It featured a separate oil supply which directly injected oil into the gasoline prior to combustion (traditionally riders had to pre-mix oil into gasoline together before filling the gas tank on two stroke engines). In 1967 a new larger displacement model was added to the range, the 350cc two stroke twin R-1.

In 1968 Yamaha launched their first four-stroke motorcycle, the XS-1. The Yamaha XS-1 was a 650cc four-stroke twin, a larger and more powerful machine that equaled the displacement and performance of the popular British bikes of the era, such as the Triumph Bonneville and BSA Gold Star. Yamaha continued on with both the two-stroke line and four-stroke twins at a time that other Japanese manufacturers were increasingly moving to four cylinder four-stroke machines, a trend led by Honda in 1969 with the legendary CB-750 four-stroke four-cylinder cycle.

In the early 1970s, Yamaha added reed-valve induction to its previously piston-ported designs to produce the twin-cylinder RD and single-cylinder RS families, with variants in a number of capacities. There was a persistent, but apocryphal, rumour to the effect that "RD" indicated race developed. In fact, "R" appears to have indicated reed valved, "D" the twin (or double) cylinder models and "S" the single-cylinder models. The RD family would be developed through the 1970s and 1980s, gaining solid wheels, water-cooling, YPVS, and other newer technology 'til they had little in common with the original variants (before being supplanted by the TZR). The RS family was produced for many years in a large number of variants by Yamaha and then Escorts Limited in India without losing its resemblance to its progenitors. In addition to the RD and RS standards, Yamaha also manufactured small standards with stamped steel frames and rotary disc-valved motors such as the Yamaha FS1, and step-through V-50 and V-80 designs. Its Enduro trail bike was replaced by the DT models. Not until 1976 would Yamaha answer the other Japanese brands with a multi-cylinder four stroke of their own. The XS-750 (and later 850) a 750cc triple cylinder machine with shaft final drive was introduced almost seven years after Honda's breakthrough bike. Yamaha's first four-cylinder model, the XS-1100 followed in 1978, again with shaft drive.[11] Despite being heavier and more touring oriented than its rivals it produced an impressive string of victories in endurance racing.

The 1970s also saw some of the first dedicated off-road bikes for off-road racing and recreation. Yamaha was an early innovator in dirt-bike technology, and introduced the first single-shock rear suspension, the trademarked "Monoshock" of 1973.[12] It appeared in production on the 1974 Yamaha YZ-250, a model which is still in production, making it Yamaha's longest continuous model and name.

Yamaha continued racing throughout the 1960s and 1970s with increasing success in several formats. The decade of the 1970s was capped by the XT500 winning the first Paris-Dakar Rally in 1979.[13]

By 1980 the combination of consumer preference and environmental regulation made four strokes increasingly popular. Suzuki ended production of their GT two stroke series, including the flagship water-cooled two-stroke 750cc GT-750 in 1977. Kawasaki, who had considerable success throughout the 1970s with their two-stroke triples of 250cc, 350cc, 500cc and 750cc ended production of road-going two strokes in 1980. Yamaha bucked this trend and continued to refine and sell two-strokes for the street into the 1980s. These bikes were performance oriented, water-cooled twin cylinder machines, designed to achieve excellent performance taking advantage of the lower weight of two strokes. The RZ-250 of 1980[14] was the progenitor of this series. The RZ-350, the largest displacement model, was a popular hot-rod bike of the 1980s and continued to be sold in some countries into the early 1990s.

Throughout the 1980s the motorcycle industry gradually went from building a few basic but versatile models designed to work well in many roles, to offering many more specialized machines designed to excel in particular niches. These included racing and performance street riding, touring, motocross racing, enduro and recreational off-road riding, and cruising. Yamaha branched out from the relatively small number of UJMs (Universal Japanese Motorcycle) at the start of the decade to a much larger set of offerings in several clearly defined markets at the end of the decade.

The XV750 of 1981 featured an air-cooled V-twin four-stroke engine and cruiser styling, and was one of the first Japanese cruiser style motorcycles. By the end of the 1980s Yamaha had offered dozens of cruiser styled bikes in a variety of displacements and engine configurations.

The RZV500 was one of the first "repli-racers", a near copy of Kenny Roberts competition GP bike, it featured a liquid-cooled two-stroke motor of 500cc displacement in a V4 configuration, along with a perimeter frame and full fairing.[15]

A more popular and practical high-performance model for the street was introduced in 1985, the FZ750. It was an innovative 750cc four-stroke inline four cylinder model. It was the first motorcycle to feature a five-valve cylinder head, something Yamaha became well known for. It also featured a cylinder block canted forward at 45 degrees, and a box-section steel perimeter frame. Production of the FZ continued until 1991.

Another bike that was performance-oriented was the Yamaha RX-Z, introduced in 1985 as a two-stroke naked sport bike, related to the Yamaha RX-135 and Yamaha RD-135, borrowing its chassis and platform. Originally equipped with a five speed transmission and a solid front disc brake rotor with rear drum brakes, it was popular in Malaysia and Singapore. After a few years on the market, the engine was upgraded with the installation of a six-speed transmission, together with a newer instrument panel and handlebar switches, as well as a cross-drilled front disc brake rotor, while the rear remained with the drum brakes. The design was unchanged until it was updated in 2004, with the rear lights being borrowed by the Yamaha Y125Z and a new headlight. It was also installed with a catalytic converter, which reduced its horsepower to 19bhp. However, the maximum torque remained unchanged but the low-end torque was improved compared to the early models. Some owners of the earlier RX-Z motorcycles may have problems during take-off because the engine tends to stall when an inexperienced rider tries to take off in the first gear. However, the problem was resolved in the new model. In Malaysia, this bike was associated with street racers and was featured in many Malay movies. In 2011, after 26 years, it was discontinued.

In 1998 Yamaha marketed a 1000cc four cylinder road bike called the YZF 'R1', this model introduced a new style of gearbox design which shortened the overall length of the motor/gearbox case, to allow a more compact unit. This, in turn allowed the motor to be placed in the frame further forward, designed to improve handling in a short wheel-based frame.[16]

In 1995, Yamaha announced the creation of Star Motorcycles, a new brand name for its cruiser series of motorcycles in the American market. In other markets, Star motorcycles are still sold under the Yamaha brand. This was an attempt to create a brand identity more closely aligned with the cruiser market segment, one of the largest and most lucrative in the USA.

In 2007, Yamaha established the Philippine operations and distributes Yamaha motorcycles under the corporate name of Yamaha Motor Philippines, Inc., one of more than 20 worldwide subsidiaries operating on all continents.

Yamaha XS650 vertical-twin

Yamaha purchased small engine maker Subaru Industrial Power Products from Subaru in October 2017. Subaru's engines powered lawnmowers, generators and water pumps and have since been rebranded as Yamaha.

Yamaha-built DOHC V6 Ford Taurus SHO engine

Yamaha has built engines for other manufacturers' vehicles beginning with the development and production of the Toyota 2000GT (1967). The cylinder head from the Toyota 4A-GE engine was developed by Yamaha and built at Toyota's Shimayama plant alongside the 4A and 2A engines.[22]

In 1984, executives of the Yamaha Motor Corporation signed a contract with the Ford Motor Company to develop, produce, and supply compact 60° 3.0 Liter DOHC V6 engines for transverse application for the 1989–95 Ford Taurus SHO.[23][24] From 1993 to 1995, the SHO engine was produced in 3.0 and 3.2 Liter versions. Yamaha jointly designed the 3.4 Liter DOHC V-8 engine with Ford for the 1996–99 SHO. Ford and Yamaha also developed the Zetec-SE branded 4-cylinder engines used in several Ford cars like the small sports car Ford Puma.

From 2005 to 2010, Yamaha produced a 4.4 Litre V8 for Volvo. The B8444S engines were used in the XC90 and S80 models, whilst also adapted to 5.0L configuration for Volvo's foray into the V8 Supercars with the S60. British sportscar maker Noble also uses a bi-turbo version of the Volvo V8 in their M600.

All performance-oriented cylinder heads on Toyota/Lexus engines were designed and/or built by Yamaha. Some examples are the 1LR-GUE engine found on the 2010–2012 Lexus LFA, the 2UR-GSE found in Lexus ISF, the 3S-GTE engine found on the Toyota MR2 and Toyota Celica GT4/All-Trac, the 2ZZ-GE engine found on the 1999–2006 Toyota Celica GT-S and Lotus Elise Series 2, and the Toyota 4GR-FSE engine found on the Lexus IS250.[25]

Yamaha also tunes engines for manufacturers, such as Toyota, so Yamaha logos are on Toyota S engines.[26]

Yamaha also tried to produce a supercar in the 1990s, named the Yamaha OX99-11. It was made as a supercar to have a Yamaha Formula 1 engine as its powerplant and have Formula 1 technology in it. Even though their engines did not win a Grand Prix, by 1991 the team had produced a new engine, the OX99, and approached a German company to design an initial version of the car. Yamaha was not pleased with the result as it was too similar to sport cars of that time, so it contacted IAD to continue working on the project. By the beginning of 1992, just under 12 months after starting to work on the project, IAD came with an initial version of the car. The car's design was undertaken by Takuya Yura, and was originally conceived as a single seater; however, Yamaha requested a two-seater vehicle and a tandem seating arrangement was suggested which was in keeping with Yamaha's motorcycle expertise. This resulted in a radical and somewhat outrageous design based on Group C cars of the time, with features such as the cockpit-locking roof. It also shared the same chassis as the Formula 1 car, to try to give the consumer market a pure Formula 1 experience. Eventually disagreements with IAD over the budget made Yamaha take the project to its own Ypsilon Technology which was given six months to finish the project, otherwise it would be terminated. To make matters worse, Japan was in the midst of an economic downturn, which made Yamaha believe there would be no customers for the car, and so the project was cancelled in 1994 after many delays, with only 3 prototypes in existence.

Yamaha Phazer snowmobile

In 2007, Yamaha became the only snowmobile manufacturer to use a four-stroke only across its line-up (in the United States only – the VK 540 model remained available as a 2-stroke in other markets). Yamaha had introduced 4-strokes to their line-up in 2003 with the release of the RX-1. This 4 cylinder model became the first performance-oriented 4-stroke snowmobile on the market (it was not the first modern 4-stroke snowmobile produced - that honor belongs to Arctic Cat for their Yellowstone Special (released in 2000), which was designed as a rental sled that could meet Yellowstone National Park's stringent emission requirement). However, Yamaha received much criticism for its weight disadvantage when compared to similar 2-strokes, despite its fuel economy and low-range torque. Yamaha further used 4-stroke technology to introduce the 80FI engine equipped in the Phazer and Venture Lite models in order to provide small displacement, lower horsepower models marketed towards smaller riders. This engine had one of the highest specific output of any 4-stroke in production, with 160 HP/L. Yamaha achieves this even without the use of a forced induction system. Yamaha is also a key player in the "4-Stroke Wars", which are a series of advertisements from opponent Ski-Doo, who claim their E-Tec-equipped 2-strokes are still cleaner and more efficient than 4-strokes, while Yamaha claims the 4-strokes are cleaner and more reliable.

Yamaha also broke a multi-year absence from sno-cross in the winter of 2006/2007 with their introduction of a factory race team headed by former Arctic Cat racer Robbie Malinoski. Yamaha was the first brand to win with a 4-stroke snowmobile in a professional snowcross race during 2006 at the WPSA Snowcross Championship.

In a partnership with Arctic Cat (now owned by Textron), Yamaha Motor Company supplies the 1,050cc 3-cylinder (135+ HP) and 998cc 3-cylinder turbocharged (180+ HP) engines for use in a collaborative chassis sold under each brand name. While there are similarities between the respective manufacturers' models, small differences can be noted. SR Viper (Arctic Cat 7000-series equivalent) and SideWinder (Arctic Cat 9000-series equivalent) models are equipped with Yamaha clutches and changes to certain plastic body panels (such as the color, suspension set-up, windshield and intercooler housing on turbocharged models). The suspension layout, chassis, gauge package, and handlebar switchgear remain the same between both brand's snowmobiles. This partnership was established for the 2014 model year with the introduction of the 2014 SR Viper and Arctic Cat 7000-series line-up.

In 2017, Arctic Cat and Yamaha introduced the world's most powerful snowmobile engine with the release of the SideWinder and 9000-series line-ups. Historic "Japan Built" models (such as the Apex and RS Vector lineups) and most SR Viper models were removed from production to support the sale of "hold-over" units from previous models years at MSRP. This was a new move to the industry in order to support dealerships and sell the large number of previous model year snowmobiles that have remained unsold.

The lineup currently consists of the following:

Sidewinder SRX LE (Spring Order only)
Sidewinder LTX LE (Spring Order only), LTX SE (In-Season "Sport"), & LTX DX (In-Season "Comfort")
Sidewinder XTX LE (Spring Order only) & XTX SE (In-Season "Sport")
