The Yamaha XS750 Special was a in-line three, four-stroke Naked motorcycle produced by Yamaha between 1976 and 1981. It could reach a top speed of 109 mph (175 km/h). Claimed horsepower was 67.59 HP (50.4 KW) @ 8500 RPM.
History
The Yamaha XS 750 Triple Special was produced from 1976 into the 1980s for the worldwide motorcycle market. In the United States, the last model year was 1981. These bikes are usually referred to as "Triples" because they have 3 cylinders. The first 4 model years the bike displaced 750cc. This was increased to 850cc for the final 2 model years. The Yamaha Triple was the most technically innovative bike of its day. In addition to having a 120° three cylinder crank, it also features dual overhead cams, 3 carbs, shaft drive, triple disc brakes and solid alloy wheels. The only modern street triples are the new Triumph 750cc to 955cc bikes. The shaft drive was listed as a best feature by 59 percent of the owners. “Yeah, practice a lot before you go downshifting in turns. Shafties are different!” Only dislike was the mild vibration and oil consumption.
Already famed for its two-strokes, Yamaha had every intention of continuing its growth cycle The firm's ambition in the late Seventies was to challenge the giant Honda on its home ground, the big four-stroke multi.
A Difficult Task
It was a difficult task for Yamaha to implement a new image on the big four-stroke market -already dominated by Honda, followed by Kawasaki and Suzuki -without being tagged as a copycat. Yamaha chose, with varying degrees of success, to go for technical originality, calling on outside designers to develop the technologies in which the firm was not yet experienced.
An XS of Originality
Yamaha chose the prestigious Porsche to develop the twin-cylinder engine of the TX 750 and the shaft drive of the XS750. Porsche was as good as its reputation; the XS was the sole motorcycle whose transmission incorporated a perfectly homokinetic tripode joint behind the gearbox rather than the normal cardan joint. Moreover, the Yamaha was also the only modern Japanese bike equipped with shaft final drive since Lilac had gone out ot' business in 1961. Another original feature of the XS 750 was its engine, whose three cylinders had Firing intervals of 120 degrees, with balance virtually equal to that of a four-cylinder engine (but more costly to achieve), this type of engine has the great advantage of being more narrow. But no matter how technically successful it was, it could not make headway against its four-cylinder rivals.
Engine
The engine was a air cooled in-line three, four-stroke. A 68.0mm bore x 68.6mm stroke result in a displacement of just 747.0 cubic centimeters. Fuel was supplied via a double overhead cams/twin cam (dohc).
Drive
The bike has a 5-speed transmission.
Chassis
It came with a 3.25-19 front tire and a 4.00-18 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 XS750 Special was fitted with a 5.02 Gallon (19.00 Liters) fuel tank.

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.
