Yamaha XS1100: review, history, specs

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.
Engine
The engine was a air cooled in-line four, four-stroke. A 71.5mm bore x 68.6mm stroke result in a displacement of just 1101.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive

Chassis
It came with a 3.50-19 front tire and a 4.50-17 rear tire. Stopping was achieved via dual disc in the front and a single disc in the rear. The front suspension was a Telescopic Forks while the rear was equipped with a Dual Shocks Swing Arm. The XS1100 was fitted with a 6.34 Gallon (24.00 Liters) fuel tank.
Models
The XS Eleven made its debut in 1978 as the largest capacity Japanese superbike then currently in production. It featured dual front disc brakes, a rear disc brake, shaft drive and cast wheels.

1977 - 1979 Yamaha XS 1100
The XS 1100 was Yamaha`s answer to the ever-growing Superbike cult of the `70s. Honda started it back in 68, and arguably Kawasaki and Suzuki jointly put a full stop on it come the turn of the next decade, with the Yam adding a bit of spice during the latter part.
