One of the most famous and successful privateer-built Ducati racers ever, this 750 Sport was acquired by expatriate Englishman Syd Tunstall of Syd’s Cycles, St Petersburg, Florida and raced by him in production machine events in the USA. In 1975 the Ducati – known as ‘Old Yellow’ or ‘Old Yello’ – was handed over to Syd’s son Malcolme, who stepped up to the emerging ‘Superbike’ class, winning several races and finishing 5th in the series despite the fact that the bike was virtually stock. In 1976, Malcolme and Old Yello won the very last Open Superbike race at the Sebring circuit before it closed, beating Robert Pendleton’s fully faired 997cc Yoshimura Kawasaki.

The following year the engine was rebuilt, tuned and enlarged to 885cc to maintain competitiveness in Open Superbike events, as recounted by Mick Walker in his book, Ducati Twins:
“Two seasons of hard racing had left the machine still in very good condition, but despite being very little worn, the standard con-rod assembly was replaced, since the plan was to increase the engine’s capacity. This was done by boring out to 86 mm and fitting 860GT pistons, which had been machined for a higher compression ratio. The 32mm Dell’Ortos were bored out to 36mm and factory Imola exhaust pipes were fitted, together with gutted Conti silencers to conform to AMA rules. The running gear now consisted of Lockheed brakes, a WM3 front and WM6 rear rim, both in 18” sizes.”

These upgrades certainly worked, as Malcolme - now qualified as an AMA Expert - finished the 1977 season as Florida Superbike and Grand Prix Champion. Old Yello benefited from further tuning, receiving bigger valves, Imola-profile cams, factory-specification high-level megaphones and other modifications in 1978, but the following season was temporarily retired from racing while the Tunstalls concentrated on Syd’s new 900SS-based Superbike racers.

Offered with restoration invoices and a substantial file of history and photographs, Old Yello represents the chance to acquire an historic privateer Ducati racing motorcycle possessing impeccable provenance and a unique and unrivalled competition record. Additional information regarding this machine’s more recent history is available to interested parties, upon request.
