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. Yamaha’s first motorcycle was the 1 YA-1, which had a 125 cc, single-cylinder two-stroke engine. It was launched in February 1955 and the bike won its first race, the Mount Fuji Ascent Race, in July 1955.[4] Yamaha continued producing two-stroke engines until it launched the XS-1 in 1969, with a 650 cc two-cylinder four-stroke engine. Today Yamaha produces scooters from 50 to 500 cc, and a range of motorcycles from 50 to 1,900 cc, including cruiser, sport touring, sport, dual-sport, and off-road.
