==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.
