Keeping the Ducati heritage alive by supplying top quality vintage motorcycles, parts and restoration services.

RESTORATION /MECHANICAL RESTORATION

We admire the beauty of classic Ducati engines! With years of experience rebuilding engines, gearboxes and other mechanical components, we can perform any mechanical project to keep your Ducati in top condition. Getting engines in optimum condition in a manner that faithfully reproduces the original movement requires fastidious attention to detail and a pronounced skill for precision work. We take old engines apart piece by piece and then put them together again as if they were the parts of a sensitive watch mechanism. We have the experience and the special tools available to perform such a job.

SINGLE CYCLINDER ENGINES

The overhead camshaft single cylinder Ducati engine came with several displacement figures ranging from 100 up to 450cc and was built from 1953 until 1978. All versions have vertically split aluminium unit construction, a forward inclined cylinder, a single overhead camshaft driven by a set of straight cut bevel gears from the crankshaft. For some models the engine had desmodromic valve actuation. In 1967 the 350 Scrambler was the first model to receive the upgraded engine. Although the basic architecture of the engine was unchanged, the crankcases were much wider at the rear where it mounted the frame. This engine time became known as the 'wide case', making the previous models the 'narrow case'. We can build your engine to standard specifications or we can upgrade it for racing purposes. We have a large stock of standard parts and upgrades for this engine type available.

ROUND CASE TWIN CYLINDER ENGINES

The first Ducati L-twin engine was developed in 1970, first going into production on the 750 GT. It was taken as the basis for the Imola 750-winning racers of 1972 by Paul Smart and Bruno Spaggiari. This racing success was the pivotal point for Ducati, giving the factory a way to enter the market for superbikes. Engines referred to as 'round case' are used in the 750 GT, 750 S and on the 1974 750 SS. The later was the only to feature desmodromic valve actuation. Of all Ducati engines, the round case L-twin engine is probably the one that requires the most pronounced skill to rebuild. The bevel gears have to be aligned with utmost precision. At Back to Classics we have the experienced skill to bring or keep your engine in perfect condition.

SQUARE CASE TWIN CYLINDER ENGINES

To Ducati V-twin engine was redesigned in 1974 to make production less labour intensive and to match the outer design with the angular ('square case') look of the 860 GT, the first model to feature the new engine. Displacement grew to 860cc and the bevel gears were mounted on a additional plate, making assembly less time consuming. Desmodromic valve actuation was introduced on the 900 SS. We have extensive experience in rebuilding this time of bevel drive engines and have all the tools available to handle the job.

PANTAH ENGINES

The Pantah engine is the first V-twin Ducati to feature a belt-driven camshaft, rather than the previously used bevel drive system. It is the grandfather of the two-valve Ducati engine of today. It was introduced in 1979 and came only with desmo valve actuation. Displacement ranged from 350 on the 350 SL up to 750 on the 750 F1. The engine also served as the basis for the famous TT1 and TT2 racers of 1982 and 1983. We can restore your Pantah engine or upgrade it for racing purposes.

DESMOQUATTRO ENGINES

Where the Pantah became the grandfather of modern-day two valve engines, the 851 Desmoquattro engine is the grandfather of all modern four valve engines. Introduced in 1988 it featured double overhead camshafts driven by a belt, desmodromic valve actuation, four valves per cylinder and electronic fuel injection. Although the engine was the modern way to go for Ducati, the first were in fact racers in disguise with more than 100 horsepower. Desmoquattro engines require a lot of attention throughout their life, which has not always been the case. Back to Classic has the ability to keep or bring your 851 or 888 in top condition, so you can enjoy this fabulous machine.
