Bike Garage - The Vee 2 Ritorno

The Vee Two Ritorno Twin is a modern re-creation of the ultimate bevel-drive Ducati Desmo V-Twin engine, re-manufactured for sale using the master copy Ducati mill drawings.

Externally faithful reproduction of belatedly ‘70’s/early ‘80’s Factory NCR race engine, every bit used past times Mike Hailwood to win the 1978 Isle of Mann TT on his legendary comeback victory.

Crankcases as well as other major castings are sandcast inwards high clit oestrus treated aluminium, alongside many covers cast inwards magnesium alloy.

Although externally historically accurate, all engine internals are manufactured using modern materials as well as up-to-date design.

The Vee Two Ritorno Twin engine retains the external appearance of the measure belatedly ‘70’s as well as early on ‘80’s production bevel-drive Ducati V-Twin engines, every bit required past times TT Formula 1 eligibility regulations. However, it contains the modified internal specification of the factory-developed NCR Ducati contest models.  Its re-creation has been achieved using master copy mill drawings of the 1978 NCR Factory Ducati engine every bit raced past times Mike Hailwood to victory inwards the Isle of Mann TT that same year.

This engine was never pose into production, merely was a culmination of the information acquired inwards going racing successfully past times Ducati mill engineers including Fabio Taglioni, Franco Farnè as well as Gianluigi Mengali, every bit good every bit Rino Caracchi as well as Giorgio Nepoti of NCR. This began alongside the 1-2 success of Paul Smart as well as Bruno Spaggiari inwards the 1972 Imola 200, through the factory-supported NCR Endurance team’s victory inwards the 1973 Barcelona 24 Hours, to the engines prototyped for Mike Hailwood to race inwards the 1978 Isle of Mann Formula 1 TT.

The engine is easily identified past times the external spin-on stone oil filter mounted mid-engine on the lower left manus crankcase.  It is the solely bevel-drive Desmo V-twin to travel prototyped alongside this feature, as well as was likewise fitted alongside a dry out clutch. Although it was planned to pose the engine into production, fewer than ten examples of it were inwards fact produced, as well as production was never implemented owing to internal disputes as well as corporate doubt inside Ducati at the time, which eventually led to Cagiva acquiring the companionship inwards 1985.

The internal format of the Vee Two Ritorno Twin incorporates electrical flow technology scientific discipline roofing air-cooled engine design, as well as the latest inwards available weight saving materials. Such technology scientific discipline has non previously been applied to production bevel-drive Ducati engines, as well as includes:

New pattern of cylinder as well as cylinder head

Bath tub bedchamber pattern cylinder heads alongside steeper valve angle

One slice cylinders for improved rigidity as well as oestrus transfer alongside Nikasil coated bores for reduced friction

Tapered collets on desmodromic valve gear every bit on electrical flow Ducati Superbike race engines, permitting sustained high RPM

Improved give off cease cooling utilizing stone oil spray bars as well as spray nozzles, so improving oestrus transfer as well as dissipation to permit a sustained higher mightiness output

Dry clutch scheme for lighter weight as well as to keep lower stone oil temperatures

Plain bearing large cease bearings, replacing roller bearings for added durability

High-strength lightweight reciprocating components such every bit conrods, pistons, valves etc

The crankshaft is designed alongside plainly large cease bearings, alongside a radically improved high pressure level stone oil scheme designed past times Vee Two, the centre of which is our Vee Two billet stone oil pump. This scheme includes pressure level fed gearbox lubrication.

The cylinder heads are the largest improvement over the measure Ducati items, which bring 80° included angles inlet as well as exhaust. The Vee Two Ritorno Twin has a narrowed 56° valve angle allowing an improved combustion bedchamber pattern as well as inwards plough optimised menstruum during valve overlap. With modern materials such every bit titanium for the valves, lowering reciprocating inertia, as well as upward to engagement designs such every bit tapered collets on the valve stems which positively connect the valve to the Desmo rocker, the Vee Two Ritorno Twin’s cylinder heads contain cutting border performance alongside authentic bevel crusade looks.

These modern improvements allow us to fully exploit the vast improvements available from the role of desmodromic valve operation, namely ultra-square camshaft profiles without the work of valve float.

The cost is AU$38,000 which includes a consummate digital ignition system, as well as a pick of carburettors as well as exhaust scheme options are available at extra cost.
