• One of the most famous and successful Bevel Ducati twins in America
• Substantial history file

'The most famous and successful bevel Ducati twin in America not owned by a magazine editor.' If the 1977 Daytona-winning, Phil Schilling/Cook Neilson/Cycle magazine 'Old Blue', is America's best-loved and most famous Ducati 750SS, the Tunstall/Tunstall/Cathcart 'Old Yello' is America's best-loved, most famous 750 Sport. No. Better than that - most famous 750 Sport on the planet - for it was raced first in the USA and then in the UK.

One of the most famous and successful privateer/non-factory-built Ducati racers ever, this 750 Sport was acquired new by expatriate Englishman Syd Tunstall of Syd's Cycles, St. Petersburg, Florida and raced by him in production road racing events in the USA. In 1975, the Ducati – known then as 'Old Yellow', more recently as '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 national 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 bevel-drive 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 an 18-inch diameter. 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.

Alan Cathcart acquired the bike and went on flying the flag in the UK with some considerable success. Malcolme Tunstall and Alan Cathcart agree that the bike ran over 300 races between them without ever suffering a mechanical failure or going down. The bike was acquired by a Steven Higham then of Wigan in the mid-to-late 1990s who planned to continue racing it. With the help of Steve Wynn (of Mike Hailwood TT fame) it was rebuilt with the last set of Getrag close ratio gears made for the Hailwood bike. Plans changed and it was never raced and was then eventually sold at the 2007 Bonhams Collectors' Motorcycles auction in San Francisco. Offered with some 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.

The bike was last run in 2014 at the Barber Motorsports Park track in a demo ridden by Alan Cathcart. It has been carefully stored in a climate-controlled facility ever since.
