Ducati Desmosedici RR, 2010
DUCATI DESMOSEDICI RR: THE ULTIMATE DUCATI EXPERIENCE
The dream of a true GP replica has finally come true and the Desmosedici RR will be the first-ever road-going motorcycle to offer such a stunning wealth of performance and technology that comes directly from Ducati's experience in MotoGP. The RR derives from the Ducati Corse Grand Prix racing Desmosedici GP6, the same bike with which Loris Capirossi and Sete Gibernau are competing with in the 2006 MotoGP World Championship.
The body design and the aerodynamics faithfully reflect the Desmosedici GP6. The colour scheme, the fittings, the 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 expression of the most extreme MotoGP racing machine today.
This is the new frontier of Ducati 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 Engine
The Ducati Desmosedici RR features advanced technology and aerodynamics that are derived from the GP6 currently being raced in the 2006 MotoGP World Championship.
The engine of the Desmosedici RR accurately reflects that of the MotoGP bike: Ducati's traditional desmodromic distribution, guaranteeing precise valve control up to the highest revs, is perfectly matched to the 989 cc four-cylinder 'L' layout, with four titanium valves per cylinder, in asymmetrical Twin Pulse configuration, producing 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 Grand Prix engine is completed by a six-speed transmission, which retains its 'racing' characteristic by being cassette type, and a hydraulically actuated dry multi-plate slipper clutch.
The aim of producing a light but robust engine has led not only to an unrivalled quality component design but also the use of exclusive racing-derived materials: sand-cast, aluminium crankcase and cylinder heads, titanium connecting rods and valves, sand-cast magnesium engine covers.
Four 50 mm Magneti Marelli throttle bodies are present, with 12-hole 'microjet' injectors. For sophisticated management of the powerful four-cylinder engine a Magneti Marelli 5SM ECU and high-speed CAN line electronics have been used.
An all-time 'first' comes with the use of a '4 into 2 into 1' exhaust, with "vertical exit" silencer, hidden in the tail cover.
These are all benchmark performance features for a MotoGP replica bike, which is capable of delivering more than 200 hp of power with the 102 dB racing silencer and dedicated CPU race kit.
Amazingly the Desmosedici RR with its catalytic oxygen sensor exhaust, homologated for road use, fully complies with Euro3 emissions regulations.
The Chassis
The engine clearly represents the beating heart of this fantastic motorcycle, but the technological advancements also extend to the chassis: a signature tubular trellis hybrid frame, refined components, and a superb carbon fibre body. This is a motorcycle that is destined for an expert rider, someone who is always looking for extreme sporting performance, as well as being an exclusive, esoteric, reliable product that is 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 men behind the Desmosedici MotoGP, who was also responsible for the aerodynamics package which is aimed at achieving maximum speed and excellent handling. The bike is totally inspired by the racing machine, the Ducati Desmosedici GP6, from which it inherits all the aggressiveness of its lines. It is fitted with a new lightweight multifunction dashboard, developed in collaboration with Ducati Corse, the same one that will be fitted to 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 abilities 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 frame geometry that is the same 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 seat support in high temperature resin type carbon fibre. This material, normally used only on racing 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 give the RR a high level 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 above the swingarm and to a rocker, which is hinged to the crankcase.
The front suspension features 43 mm upside-down Öhlins FG353 pressurized forks (PFF), with TiN coated sliders. The forks, which come directly from competition use, as well as being pressurized thus ensuring excellent track performance, are fully adjustable in preload, rebound and compression.
