Ducati
Desmosedici RR - THE DESMOSEDICI RR TESTED AT THE MISANO
WORLD CIRCUIT
To celebrate Casey Stoner's umpteenth victory
in the seat of a Desmosedici at the Misano World Circuit,
Ducati organized a workshop at the circuit in Misano
Adriatico dedicated to the street replica of the MotoGP
racing bike.
Some of the most important sector journalists
of the world were invited to a dynamic test of the Desmosedici
RR, including in-depth explanations of the engine, chassis/vehicle
and tyres by Ducati and Bridgestone engineers. For this
occasion, Ducati was able to release the last bits of
information about the details of the bike whose production
will begin in October.
Check out all the details in the complete
description of the engine and in the thorough analisys
of the vehicle, not to mention the tech specs as well
as the most recent pictures - including the ones takes
on the Misano racetrack.

VEHICLE DETAILS
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 has been fitted to the racing machine,
the Desmosedici GP7.
Desmosedici-style digital instrumentation
is taken from Ducati's MotoGP GP7 project. This pure
racing, minimalist solution by Digitek has no switches
or buttons to compromise its clean lines. The wide screen
allows the rider to read six values at the same time
and to scroll through and select from various menus
by handlebar-mounted switch gear.
Activating the Ducati Data Analyser (DDA)
riders are able to acquire up to 2MB of data (approximately
3.5 hours). The system records several channels of data
including: vehicle speed, engine rpm, throttle opening,
engine temperature, distance travelled, laps and lap
times. So riders are able to compare, analyse and get
an inside view of the Desmosedici RR performance.
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, 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 FG353P 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 a 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 and Bridgestone have developed 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 that enables the right brake lever
position to be found during the ride. The pair of front
brake discs are two semi-floating 330 mm x 5 mm discs,
with machined flange. The Brembo rear brakes are made
up of a 240 mm fixed disc and a calliper with two 34
mm pistons.
The Desmosedici RR's new exhaust system
has been specifically developed to deliver the best
power and at the same time to ensure road riding pleasure.
Significantly lighter, it has been engineered with a
power-increasing 4-2-1 layout that uses 42mm diameter
tubing with wall thickness of 0.8mm (.030in) AISI 309.
The new exhaust system is equipped with a pass-by valve
and ends with a silencer incorporated in the rear tail
that features two exhaust exits to vertically release
the exhaust gas. The upper part of the rear tail combines
a ceramic carbon fibre cover, the same solution as single-seater
F1 cars. The Desmosedici RR will be available with a
special race kit that includes a 102 dB racing exhaust,
a dedicated CPU, bike cover and paddock stand.
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, this has a broad white stripe
on the fairing. A team sponsor decal kit will be provided
with each bike.
For this exclusive Ducati, a new dedicated
service plan is included. Each Ducati Desmosedici RR
owner can benefit from a three-year warranty and three
years of scheduled maintenance, free of charge.
ENGINE DETAILS
With a power output of 200 HP* at 13,800 rpm and a torque
of 11.8 kgm* at 10,500 rpm, the new D16RR engine follows
the guidelines laid down by the Ducati Corse GP engine,
a masterpiece of engineering and precision.
Bore and stroke measurements are the same as those on
the D16GP6 - 1000 cc (86x42.56), as are the characteristic
positions of the Ducati desmodromic timing system parts
(camshaft rotation axis, rocker arm centre and valve
centre distance), valve angle, distance between cylinder
centres and pulse timing, which uses the Twin-pulse
solution applied on the racing engine.
As in MotoGP, traditional Ducati desmodromic
timing ensures accurate valve control even at the highest
revs and blends perfectly with the modern architecture
of this superb 4-cylinder engine. As is the tradition
at Ducati, the 90° angle between the cylinders is
maintained.
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 reliable
engine has led not only to a component design of unrivalled
quality, but also to the use of exclusive, individually-made
racing-derived materials.
The crankcase and cylinder heads are sand-cast
aluminium while the cam-drive cover and alternator casing
are made of sand-cast magnesium, technologies that match
the lightness of these alloys with the greater mechanical
strength expected from structural components. The oil
sump, cam covers and clutch cover are made by pressure
die-casting magnesium alloy, a technology that allows
significant thickness reduction on non-structural components.
A look inside the engine shows how the quest for high
performance has led to the utilisation of racing technologies
such as titanium con rods, intake and exhaust valves
- again in titanium alloy with CrN (chromium nitride)
coating - and precision grinding finishing to reduce
friction on certain components such as rocker arms.
Even the camshafts have been drilled and cut to reduce
weight.
Lightened through finite-element simulation (FEM), the
timing gears are arranged according to a pattern highly
similar to the one used in the GP engine. The piston
has the classic high-performance engine architecture,
with double ribbed undercrown and a compact combustion
chamber that brings the compression ratio to 13.5.
The crankshaft rotates on brass bearing
shells and has the crank pins offset by 70° to generate
soft pulse timing (pulses at 0° - 90° - 290°
- 380°). This component is produced via complete
precision machining of a single piece of forged steel.
The cone-shaped end of the crank-webs
maximises the use of the available space below the piston
bosses and optimises crankshaft assembly balance.
The sand-cast aluminium crankcases feature
integral cylinder bores with Nicasil lining, and the
crankcase halves' separation layout is the same as on
the GP engine. The oil pump is of the trochoidal (Gerotor)
type and controls the water pump according to a cascade
arrangement.
Also featured are four 50mm Magneti Marelli
throttle bodies with 12-hole 'microjet' above-throttle
injectors. A Magneti Marelli 5SM ECU control unit and
high-speed CAN line electronics have been employed to
manage the injection and electronic ignition of the
powerful four-cylinder engine. The throttle bodies,
while serving two opposing cylinder heads, lie on the
same plane, resulting in a straight, plunging intake
port configuration.
Like its GP counterpart, the engine acts
as a connector between the chassis and the rear swingarm/suspension,
thus playing an essential structural and stiffening
role.
This road-going MotoGP bike offers outstanding
performance: when in its racing configuration, that
is, with the kit consisting of the supplied racing exhaust
(102 dB) and control unit, it can reach a maximum power
of 200 HP.
With its catalysed exhaust system, the
Desmosedici RR, type-approved for on-road riding, is
compliant with Euro 3 emissions standards.
