Ducati Unveils Desmosedici RR

Ducati introduced details of its Desmosedici RR production machine — a machine based closely on the MotoGP weapon campaigned by Ducati. Simply put, Ducati claims this will be the highest performance production motorcycle available. Expect it to go on sale in July, 2007. You can reserve your Desmosedici RR at your Ducati dealer now (if you have plenty of disposable income).

Ducati chose the occasion of this weekend’s Mugello GP for the introduction of the Desmosedici RR. Production will be limited to approximately 400 bikes per year. Here is some of what Ducati had to say about the new bike, including the spec sheet (at the bottom):

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.

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.

The rear shock is also Öhlins and has rebound, low/high speed compression adjustment and hydraulic preload adjustment.

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 helps to reduce unsprung weight and inertia, all the while improving handling and suspension response.

With the aim of producing the ultimate track performance, Ducati in collaboration with Bridgestone is developing special tyres for the Desmosedici RR. The tread pattern, construction and profile are being specially developed and produced by the Japanese tyre manufacturer.

The numerous racing components of this high-performance machine also include its Brembo brakes. Up front the Desmosedici RR features a new pair of radial ‘monoblock’ callipers with four 34 mm pistons: monoblock technology, until now only used for racing callipers, allows calliper stiffness to be increased, thus improving braking response; the front brake system is completed by a radial master cylinder, with hinged lever and remote ‘quick’ adjuster. The pair of front brake discs are the same as those used on the GP6 in its wet weather race set-up: two semi-floating 320 mm x 6 mm discs, with machined flange. The Brembo rear brakes are made up of a 240 mm fixed disc and a floating calliper with two 34 mm pistons.

The Desmosedici RR will be available with a special race kit that includes a 102 dB racing exhaust, a dedicated CPU, bike cover, paddock stand.

For this exclusive Ducati, a new dedicated service plan is included.

Each Ducati Desmosedici RR owner can benefit with a three-year warranty and three years of scheduled maintenance, free of charge.

Two versions of the RR will be available: 1) the Desmosedici RR – painted in ‘Rosso GP’, with a white number plate on the tail section; 2) the Desmosedici RR ‘Team Version’ – painted in ‘Rosso GP’, and as with the factory Corse bikes, has a broad white stripe on the fairing.

A team sponsor decal kit will be provided with each bike.
