1984 SUZUKI XN85 TURBO TYPE GP71A


Serial number 100B03
Sold with a copy of the French car registration document.

Of the four Japanese manufacturers, Suzuki was probably the most reticent about the turbo wave. This technique was hardly part of the brand's sober habits, but fashion being the rule, the game had to be played. This was done, without much conviction but with seriousness, Suzuki chose a classic 650, like Yamaha, as a base, but deigned to add a Mikuni-Bosch L-Jetronic injection system. The turbo was installed above the gearbox, a discreet but poorly ventilated location far away from the cylinder head exhaust pipes. In conjunction with its respectable caliber, this arrangement didn't have a very beneficial effect on performance: like the Yamaha, the XN 85 (so called because of its 85 horsepower) proved to be barely better than the base 650, and its overly wise engine could in no way claim to offer any "turbo effect". In fact, it was the chassis that made the XN 85 make history. The show car prototype benefited from a sealed chain case that was discarded in the production version, but the XN 85 was, along with the Honda VF 750 F, the first production machine with a 16-inch front wheel. Combined with a generally very successful chassis, this geometry saved the short career of a machine whose powertrain was disappointing in more ways than one. Shortly afterwards, this excellent balance of handling was found on the GSX 550 and 750 E.

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.
