In 1981, there was euphoria at Yamaha. Under the impetus of Hisao Koike, the three-pronged firm set itself the goal of dethroning Honda for the title of world's leading manufacturer, and the investments made to this end were enormous. Honda's stature was already much greater at the time, but Yamaha is tackling it, without complex, on all fronts, by feverishly renewing and completing its range. The XZ 550, an all-new medium-displacement twin-cylinder engine, is the result of this excitement. With its four overhead camshafts, four valves per cylinder and liquid cooling, the XZ 550 is a high-performance machine, but the four-cylinder competition (especially the very successful Kawasaki at the time) will still have the advantage in this regard. It's aesthetically innovative, with its angular lines and offset rear axle fork, but it will only manage to shock. A development to be completed Commercially speaking, its shaft drive deters sports enthusiasts while "tourists" remain wary of its sophisticated technology. Worse, the mechanics are sloppy, and the carburetion problems will never be solved. The XZ's reputation will quickly suffer, and dealers will have to sell off the last units in an early S version equipped with a fairing. Promising but a victim of Koike's excessive ambitions, the XZ remains the symbol of Yamaha's wanderings during this period.

Serial number 504216 Sold with a copy of the car registration document. Sold with its saddle At the beginning of the seventies, Honda still dominates the market despite a breathtaking progression of Yamaha (more than 28,000 Honda's sold in France in 1972 against 9,000 Yamaha's), mainly present with its very sporty 250 and 350 two-stroke twins. Yamaha, which has only had one four-stroke in its catalogue since 1970, the XS 650 two-cylinder, wants to enter the big door and with a certain originality into the clan of large-engine producers. The superb prototypes of the GL 750 with a liquid-cooled, fuel-injected, two-stroke, four-cylinder engine, followed by the RZ 201 with a rotary engine, presented in 1971 and 1972 respectively, bear witness to this ambition and to the brand's hesitation as to which choices to make. In the end, a completely different path was chosen. In 1972, Yamaha marketed its first big modern four-stroke, the TX 750. Face at the sporty 900 Z1 Kawasaki sold in 1973, Yamaha chose the path of wisdom by settling for a four-stroke twin that was more oriented towards grand touring and intended to take up the torch left behind by the British twins, with a more important feature: the elimination of the vibrations normally inherent to twins set at 360° by chain-driven balancers. The idea was brilliant and will go a long way. Unfortunately, this first realization had some youthful flaws, the TX overheated and proved to be very fragile. 4-stroke air-cooled twin-cylinder with 360° air cooling - Balancers - 743 cm3 (80 x 74 mm) - 63 hp/6,500 rpm - 2 Mikuni-Solex carbs - 5-speed gearbox - Electric starter and kick - Chain drive - Double cradle frame - Front suspension - Front suspension - Front suspension - Front suspension - rear suspension. ¬Telescopic, oscillating rear - Disc/drum braking - 19" front wheel, 18" rear - 19 l fuel tank - 220 kg - 195 km/h. Elegant and rounded, the 1972 TX was later fitted with a large oil cooler to improve reliability. This Yamaha TX 750 is in good overall condition. Its seat and side covers were installed after the pictures were taken. Its engine is not blocked.
