The XS 750 and XS 850  were produced from 1976 to 1980. The US  enjoyed this bike one year more. Because they had three cylinders, everybody knows the bikes as "Triples". At the beginning, the bike displaced 750cc and later the engine was increased to 850cc, so, the XS750 changed into a new XS850 machine. The Triples had electronic ignition from 1978.
