Vehicle Information
Yamaha XS850 Motorcycle - Street (1980-1981)
The Yamaha XS850, produced from 1980 to 1981, is a classic three-cylinder motorcycle known for its robust 826cc air-cooled engine. As a successor to the XS750, it offered enhanced displacement and performance, featuring a DOHC, 2-valve per cylinder design, a 5-speed manual transmission, and a reliable shaft final drive. This model was positioned as a versatile Universal Japanese Motorcycle (UJM), available in various trims to suit different rider preferences. For the 1980-1981 model years, the Yamaha XS850 maintained consistent engine specifications across all versions. While the XS850 itself represented a significant engine upgrade from its predecessor, the XS750, there were no major mid-cycle generation or engine changes within the 1980 and 1981 production years. Differences primarily involved aesthetic variations and styling packages, such as the Standard, Special, and the distinctive Midnight Special trims, which featured unique paint schemes and accents.
