The [[Yamaha]] '''XS Eleven'''/'''XS1100''' [[motorcycle]] was produced by [[Yamaha]] from 1978 to 1981. It was a [[superbike]] powered by an [[air-cooled]] 1102cc [[4-stroke]], [[DOHC]] [[Straight-4|inline four-cylinder]] [[engine]] mounted transversely in a duplex [[cradle frame]].  At the time of it's release in 1978 the XS11 was the fastest production motorcycle in the world. It was supposed to be an Eleven second bike hence the Eleven name instead of 1100.  It could reach a top speed of 134 mph (215 km/h). Max [[torque]] was 66.38 ft/lbs (90.0 Nm) @ 6500 RPM. Claimed [[horsepower]] was 92.93 HP (69.3 KW) @ 8500 RPM. 
There were three models: the standard style XS Eleven, factory custom XS Eleven Special, and XJ1100 Maxim. The standard model, first released in 1978, had a larger, 5.4 gallon tank than the ''special's'' (1979 and up) 4.5 gallon tank, as well as a larger rear tire and wider handle bars. The special had "buckhorn" style handlebars and a leading front axle, giving it more of a cruiser look. In '80 and '81 [[Yamaha]] offered a "Midnight Special" version (all across the XS line) with a black tank (with gold flakes) and gold trim/side covers/wheels.

The Yamaha XS Eleven/XS1100 motorcycle was produced by Yamaha from 1978 to 1981. It was a superbike powered by an air-cooled 1102cc 4-stroke, DOHC inline four-cylinder engine mounted transversely in a duplex cradle frame. At the time of it's release in 1978 the XS11 was the fastest production motorcycle in the world. It was supposed to be an Eleven second bike hence the Eleven name instead of 1100. It could reach a top speed of 134 mph (215 km/h). Max torque was 66.38 ft/lbs (90.0 Nm) @ 6500 RPM. Claimed horsepower was 92.93 HP (69.3 KW) @ 8500 RPM.

There were three models: the standard style XS Eleven, factory custom XS Eleven Special, and XJ1100 Maxim. The standard model, first released in 1978, had a larger, 5.4 gallon tank than the special's (1979 and up) 4.5 gallon tank, as well as a larger rear tire and wider handle bars. The special had "buckhorn" style handlebars and a leading front axle, giving it more of a cruiser look. In '80 and '81 Yamaha offered a "Midnight Special" version (all across the XS line) with a black tank (with gold flakes) and gold trim/side covers/wheels.
