Ducati launched the Desmosedici RR production prototype during the magical atmosphere of the 2006 Italian Grand Prix at Mugello. The dream of a real GP replica has finally come true as the Desmosedici RR will be the first ever road-going motorcycle to offer the stunning performance and technology taken directly from MotoGP.
The RR is derived from the Ducati Corse Grand Prix racing Desmosedici GP6, the same bike which Loris Capirossi and Sete Gibernau have used to compete in the 2006 MotoGP World Championship.
The Mugello launch was the perfect occasion to reveal the shape and the technical characteristics with which the bike will arrive on the market, confirming the high technological features of this exclusive and esoteric machine.
The aerodynamic body design faithfully reflects the Desmosedici GP6. The colour scheme, components and materials used in its construction as well as the technical features of the powerful four-cylinder Desmodromic engine, built by the Borgo Panigale factory engineers, leave no doubts whatsoever: the Desmosedici RR is the ultimate road expression of the most extreme MotoGP racing machine today.
Having been possible to reserve the bike through the official Ducati dealer network since June 2nd 2006, the project is currently in the industrialisation phase and, as previously announced, will be a limited edition motorcycle. The RR is scheduled to arrive on the market in July 2007 with Ducati 999R owners receiving delivery priority.
This is the new frontier of Ducati’s technological evolution, a dream come true. Demonstrating once again the courage and the passion of Ducati as well as the ability to transfer the experience of the racing world to a machine that is destined for road use.
The Ducati Desmosedici RR features the most advanced technology and aerodynamics derived directly from the GP6 raced in the 2006 MotoGP World Championship. The engine of the Desmosedici RR accurately reflects that of the MotoGP bike. Ducati’s traditional Desmodromic system guarantees precise valve control at the very highest revs and is the perfect application for the 989cc, four titanium valves per cylinder, L-Four layout. This awesome powerplant, which is prepared in asymmetrical Twin Pulse configuration, is a masterwork of precision engineering.
The double overhead cams are gear driven, a sophisticated and reliable solution that enables precise valve timing in all conditions. This authentic copy of the GP engine is further endorsed by the use of a cassette type six-speed gearbox and hydraulically actuated dry multi-plate slipper clutch.
The aim of producing a light but robust engine has led not only to component design of an unrivalled quality, but also the use of exclusive racing-derived materials including sand-cast aluminium crankcase and cylinder heads, titanium connecting rods and valves and sand-cast magnesium engine covers.
A Magneti Marelli 5SM ECU and high-speed CAN line electronics have been employed for the highly sophisticated management required for the four 50mm Magneti Marelli throttle bodies and 12-hole ‘microjet’ injectors feeding the powerful four-cylinder engine.
An all-time ‘first’ comes with the use of a 4-2-1 exhaust system, with ‘vertical exit’ silencer, hidden in the tail-piece. These are the benchmark performance features for a MotoGP replica bike which is capable of delivering more than 200hp when used with the 102dB racing muffler and dedicated CPU race kit. Amazingly the Desmosedici RR with its catalytic oxygen sensor exhaust, homologated for road use, fully complies with Euro 3 emission regulations.
While the engine clearly represents the beating heart of this fantastic motorcycle, the technological advancements also extend to the chassis. The signature tubular Trellis hybrid frame and highly refined components are dressed in superb carbon fibre bodywork. This is a motorcycle that is destined for an expert rider, someone who is always looking for extreme sports performance in a product that is exclusive, reliable and more than capable of track racing.
The colour scheme of the Desmosedici RR was the work of Alan Jenkins, the designer and one of the many people behind the Desmosedici MotoGP project. He is also responsible for the aerodynamics package which is aimed at achieving maximum speed while ensuring excellent stability. Although totally inspired by the Ducati Desmosedici GP6, from which it inherits its aggressiven lines, the RR will be fitted with the latest lightweight multifunction dashboard, developed in collaboration with Ducati Corse for next year’s racing machine, the Desmosedici GP7.
The bike’s development could not have been made possible without the significant collaboration of Vittoriano Guareschi, the official Ducati Corse tester, whose riding ability and hundreds of hours of track time have made a fundamental contribution to the evolution of the project.
For the first time the Ducati Desmosedici RR uses a new welded tubular steel Trellis hybrid frame (ALS 450) with the same frame geometry as that of the Desmosedici GP6. This construction guarantees an excellent stiffness to weight ratio, allowing superior manoevrability and riding precision. Attached to the red frame is the rear subframe in high temperature resin type carbon fibre. This material, normally used only on race bikes, has the characteristic of being extremely lightweight but exceptionally rigid.
The Desmosedici RR sports a new extra-long, cast, forged and pressed aluminium alloy swingarm. The geometry and the technology of this component derive directly from the MotoGP bike and gives the RR high levels of traction, control, and excellent weight distribution as well as a superb stiffness to weight ratio.
In the suspension department the Ducati Desmosedici RR features the most advanced technical components. The rear suspension geometry and layout is the same as that of the GP6, with the rear shock attached to a rocker which pivots on the crankcase.

The front suspension features 43mm upside-down Öhlins FG353 pressurised forks (PFF), with TiN coated sliders. The forks, which come directly from competition use, are fully adjustable in preload, rebound and compression. The rear shock is also Öhlins and has rebound, low and high speed compression and hydraulic preload adjustment.
Also for the first time ever, this Ducati production motorcycle features Marchesini forged and machined magnesium alloy wheels, with 7-spoke design as on the GP6. This enhances the handling and improves suspension response by reducing unsprung weight and inertia.
With the aim of producing the ultimate track performance, Ducati in collaboration with the Japanese tyre manufacturer, Bridgestone, have developed special tyres for the Desmosedici RR with a dedicated tread pattern, construction and profile.
The racing components used on this high-performance machine also include its Brembo brakes. Up front, the Desmosedici RR features a new pair of radial ‘Monobloc’ calipers with four 34mm pistons. Monobloc technology, until now only used for racing, creates a much stiffer caliper thus improving the braking response. The front brake system is completed by a radial master cylinder with a race-style articulated lever and remote ‘quick’ adjuster. The front brake discs are the same as those used on the GP6 in its ‘wet weather’ race set-up, two semi-floating 320mm x 6mm discs with machined flange, while the Brembo rear brakes consist of a 240mm fixed disc and a caliper with two 34mm pistons.
The Desmosedici RR will be available with a special race kit that includes a 102dB racing exhaust, a dedicated CPU, bike cover and paddock stand. A new dedicated service plan is also included to give each Ducati Desmosedici RR owner the benefit of a three-year warranty and three years of scheduled maintenance free of charge.
Two versions of the RR will be available. The ‘Desmosedici RR’ finished in ‘Rosso GP’ with a white number plate on the tail-section and the ‘Desmosedici RR Team Version’ finished in ‘Rosso GP’ with a broad white stripe on the fairing as with the Factory race bikes. A team sponsor decal kit will be provided with each bike.
