Description

1973 HONDA CB 450


Serial number 5033966
Sold with a copy of the French car registration document.

The Honda CB450 was born in 1965.

It will remain an essential event: the one that really changed the course of motorcycle history by sounding the death knell for the British industry, until then predominant in Europe. And at the same time, it revived the motorcycle industry in general. Its engine is a real masterpiece both mechanically and aesthetically, with its two overhead camshafts rotating directly on the aluminium cylinder head, its torsion bar valve return, its vacuum carburettors, it was, in the eyes of many journalists, considered "revolutionary".
Its data sheet is as follows:
4-stroke vertical twin-cylinder air-cooled engine
Valves controlled by two chain driven overhead camshafts
Displacement 444 cm3
2 Keihin carburettors with concentric bowl, controlled by the intake depression
14-plate clutch working in engine oil

This Honda CB450 is in generally satisfactory condition. Its saddle is not original. It needs to be restarted but its engine is not blocked. Sold without keys.

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.
