Yamaha Motor Company Limited a Japanese motorized vehicle-producing company (whose HQ is at 2500 Shingai, Iwata, Shizuoka), is part of the Yamaha Corporation. After expanding Yamaha Corporation into the world's biggest piano maker, then Yamaha CEO Genichi Kawakami took Yamaha into the field of motorized vehicles on July 1, 1955. The company's intensive research into metal alloys for use in acoustic pianos had given Yamaha wide knowledge of the making of lightweight, yet sturdy and reliable metal constructions. This knowledge was easily applied to the making of metal frames and motor parts for motorcycles. Yamaha Motor is the world's second largest producer of motorcycles (after Hero Honda)[citation needed]. It also produces many other motorized vehicles such as all-terrain vehicles, boats, snowmobiles, outboard motors, and personal watercraft.


Snowmobiles
Yamaha has recently claimed a 100% four-stroke snowmobile line-up, making them the only snowmobile manufacturer to do so. In Canada though, there are still three models that Yamaha manufactures that are still two-stroke. They are the Bravo, VK 540 and the Venture XL. Yamaha had introduced four-strokes to their line-up in 2003 and the line-up became four-stroke based for model year 2005. Many say that Yamaha has proven snowmobiles can be clean, efficient, and reliable all while maintaining strong performance. The RX-1 released in 2003 was the first performance-oriented four-stroke snowmobile to ever hit the market. It was not, however, the first modern four-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, the Yamaha received much criticism for its weight disadvantage when compared to similar two-strokes, despite its excellent fuel economy and low-range torque. Yamaha is now on the cutting edge of four-stroke technology with the introducing of their 80FI engine which is equipped on the Phazer and Venture Lite models. This engine has one of the highest specific output of any four-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 "four-stroke wars", which are a series of advertisements from opponent Ski-Doo who claim their 2-tec and power-tek equipped two-strokes are still cleaner and more efficient than four-strokes, while Yamaha still claims the four-strokes are cleaner. 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.
