Yamaha XS 650 History
The xs650 was designated the XS-1 when the Yamaha XS 650 was launched in 1968 it had one of the most advanced engines in its class of large parallel twin motorcycles. The engine and gearbox are unit construction with the crankcase split horizontally for ease of assembly. The XS 650s valves are operated by a single overhead camshaft (SOHC) whereas almost all contemporaries in its class have pushrod valve gear.
The Yamaha XS 650 was produced until 1985. Over a quarter million XS650s in 40 different variations were produced by Yamaha between 1970 and 1985. The XS650 big twin, especially in America has developed a cult following for good reason. At the heart of the XS650 is a indestructible engine. The best parallel twin ever built. In the United States, the last model year was 1983 with Canada, Europe and other markets continuing into 1984 and 1985. However, many US models were left over due to overproduction and an economic recession and brand new 1982 and 1983 models could still be purchased in 1987 at some dealerships.
