The 750 GT was an instant success for the company and it was clear all along that a sporting version of this touring bike was on its way, and so the 750 Sport soon followed.
It quickly became also known as the 750 S and later on as the ‘yellow sport’, referring to the colour, but also to distinguish it form the ‘green frame’ 750 Super Sport.
The first examples took the 750 GT as a basis and had the same wide rear sub frame. The Marzocchi front fork was similar but with black painted fork legs and the bike was fitted with a single Lockheed brake system, although this was replaced very soon in 1972 with a Scarab brake system. The 750 S was fitted with clip-on handlebars and rear-set foot pegs. This early model had a very distinctive black Z-shape stripe on the newly designed fiberglass yellow fuel tank. The engine was based on GT only it had black painted covers, a lighter crankshaft, high compression pistons and larger Dell’Orto 32mm carburetors. Power output increased considerably because of the changes, up to 62 bhp at 8,200 rpm.
The 750 Sport was updated in 1973 with a narrower rear sub frame with ‘outboard’ mounted rear shock absorbers. The fiberglass fuel tank was narrower to fit the new frame and was finished with a black stripe in the centre and two smaller ones on the side with the Ducati logo. Side covers and seat were now only yellow. Scarab brakes were still fitted like on the ’72 model and also the engine was not changed, keeping its black covers.
1974 was the last official production year of the ‘round case 750 engine, before the ‘square case’ design was introduced. Other updates on the 750 Sport included new camshafts and polished rather than black painted outer engine covers and the fuel tank was now steel instead of fibre glass. Marzocchi front forks gave way to Ceriani’s and a Brembo brake system.
The Ducati 750 S is one of the all-time great Ducati’s offering spectacular handling as was demonstrated by Paul Smart and Bruno Spaggiari finishing first and second at Imola in 1972 on a 750SS, that was developed from stock bike.
This 750 special was registered in Spain during the 1980’s before ending up in a collection in Italy, like many club road / racers it was a mixture of parts, taking the best of the factory components available to build the perfect special. Having been imported to the UK it has received a major service and MoT until Nov 2016 and has been entered on the NOVA system. In generally good order this is a great opportunity to acquire a round case 750 Ducati sports bike at an entry level price as the 750SS models are now reaching six figures.
