2009 Ducati 1198
More powerful, lighter and safer
The
new Ducati 1198, while maintaining the same look as
the previous 1098, is in fact a totally new bike.
The 1198, which produces a powerful 170hp (125kW)
from its new Testastretta Evoluzione engine, and has
a dry weight of just 171kg (377lb), incorporates all
of the World Superbike technology derived directly
from the 2008 World Championship winning race bike
of Troy Bayliss.
The 1198 is powered by the powerful Testastretta
Evoluzione, a liquid cooled, L-Twin, Desmodromic engine,
the crowning glory of Ducati’s development and
perfection of the L-Twin engine, that produces 170hp
(125kW) @ 9,750rpm and a class-beating 97lb-ft (13.4kgm)
of torque @ 8,000rpm.
From data acquisition systems integrated as standard
equipment, to ingenious dual construction methods
for its weight-saving single-sided swingarm and to
the road-going Ducati Traction Control, Ducati’s
innovative trackside solutions continue to flow.
The
innovative Ducati Traction Control system, supplied
as standard equipment on
the 1198 S model, enables the retrieval and analysis
of data collected from your previous track session
or road trip. DTC monitors front and rear wheel speeds
to detect rear wheel-spin under acceleration and electronically
reduces engine power to restore traction. DTC, which
offers a choice of eight profiles, provides a considerable
increase in safety during mid-corner acceleration.
The new 1198 Testastretta Evoluzione engine
The
Testastretta Evoluzione engine is the crowning glory
of Ducati’s development and perfection of the
L-Twin engine. World Superbike dominance for almost
two decades is the result of continual commitment
to their twin-cylinder configuration. Ducati now share
the reward for that commitment as World Championship-winning
technologies flow from the factory race team into
production engines.
The incredible 1198 and 1198 S are powered by a liquid
cooled, L-Twin, Desmodromic engine that produces 170hp
(125kW) @ 9,750rpm and a class-beating 97lb-ft (13.4kgm)
of torque @ 8,000rpm.
The 1198 achieves its new capacity by using exactly
the same 106x67.9 bore and stroke as the factory race
bike. Volumetric efficiency through the four valves
per cylinder has been enhanced by increasing the valve
diameters approximately 4% to 43.5mm for the inlet
and 35.5mm for the exhaust. They are actuated by racing-type
rocker arms, ‘super-finished’ for reduced
friction and fatigue, and double overhead camshafts
with radical profiles that achieve approximately 10%
more lift than their predecessors.
These
incredible valve performances are only possible because
of Ducati’s unique Desmodromic system, where
valve closure is activated mechanically. At high rpm
it would be almost impossible for the valve to follow
the steep closure profile of the cam lobe if it were
relying upon a normal valve spring. With the Desmo
system, the valve is closed mechanically with the
same accuracy as it is opened, enabling steep cam
profiles and radical cam timings. This system is used
on every single Ducati motorcycle including their
world-beating Superbike and Desmosedici MotoGP bikes.
With increased capacity and improved volumetric efficiency,
the elliptical throttle bodies have also increased
in cross-sectional area by 13.3% compared to the 1098.
Now boasting a size equivalent to 63.9mm diameter,
the inlet body is exactly the same as the ‘R’
model.
The
race-designed 1198 pistons have a distinctive double-ribbed
undercrown to achieve high strength and reduced friction
by using minimal piston wall surface area. Using technology
developed for the Desmosedici MotoGP project, the
design enables reliable operation of the 106mm diameter
pistons when performing at high rpm.
The 1198 Testastretta Evoluzione engines are the
lightest ever used in Ducati Superbikes, thanks to
a new crankcase manufacturing technology which reduces
weight by an incredible 3kg (6.5lbs). The vacuum die-cast
process ensures consistent and precise wall thickness
and increased strength from absolute material purity.
The weight-saving cam covers in magnesium-alloy are
evident by their gold colour, while the alloy outer
clutch and generator covers now sport a black finish.
In line with the increased power and torque output,
the 1198 gearbox introduces ‘R’ model
internal ratios. The new gears are machined from the
same high-strength steel used in Ducati Corse race
applications and are subjected to a shot-peening treatment
that further ensures their strength and reduced fatigue.
The 1198 and 1198 S feature a beautiful and efficient
exhaust system. Incredibly lightweight, it has been
engineered with a power-increasing symmetrical 2-1-2
layout that uses 52mm-57mm diameter tubing with a
wall thickness of 0.8mm (.030in). It is equipped with
a catalytic converter and two lambda probes for smooth
engine mapping and Euro3 conformity. The system terminates
with Ducati’s trademark twin under-seat silencers,
delivering that unmistakable signature sound of the
big bore Desmo 90° L-Twin.
Superbike Technical Chassis
Advanced chassis
The 848 , 1198 and 1098 R chassis and suspension
received detailed study and a ‘performance-first’
priority approach to development. The goal was to
achieve considerable weight saving and build-in strength
and rigidity to manage the high-powered Testastretta
Evoluzione engines. While the ‘R’ models
are purely ‘monoposto’, Ducati built ‘biposto’
practicality into the 848 and 1198 with a passenger
seat and footpegs. As with the race bikes from which
they are derived, each and every component is designed
to contribute to achieving superior road holding and
stability.
Trellis frame
Developed in cooperation with Ducati Corse, the
lightweight Trellis frame features 34mm main section
tubes with a material thickness of 1.5mm. The result
is an incredibly rigid construction that remains one
of Ducati’s lightest frame solutions ever. Adding
style to performance, the two colour versions for
the 848 use frames finished in ‘red’ and
‘racing grey’ while both colours for the
1198 use ‘racing black’ frames and both
1198 S a sophisticated ‘bronze’ finish.
The 1098 R frame is finished in ‘red’
.
Front suspension
Both the 848 and 1198 feature fully adjustable 43mm
Showa forks, with an additional special low friction
titanium oxide treatment applied to the sliders of
the 1198, while spectacular 43mm Öhlins with
low friction titanium nitride-treated sliders are
used on the 1198 S and 1098 R. Both front suspension
solutions have radial brake caliper mountings providing
superior road holding and incredible feedback to give
every rider more confidence and control.
Rear suspension
The lightweight Trellis frame and single-sided swingarm
have enabled a compact and weight-saving rear suspension
linkage system that features separate lower pick-up
points for the push-rod and suspension unit. This
‘tandem’ design effectively reduces stress
around the linkage pick-up area of the Trellis frame.
Working together with this highly efficient linkage
is a fully adjustable Showa single shock for the 848
and 1198, and an incredible Öhlins unit for the
1198 S. The higher specification Öhlins for the
rear of the 1098 R uses TTXR twin tube technology
and offers totally separate damping adjustment in
compression and rebound. It uses experience gained
in MotoGP to minimise friction and reduce the risk
of cavitation under extreme conditions. The 1198,
1198 S and 1098 R rear suspension system has an adjustable
rear ride-height, independent of spring pre-load and
other suspension settings - valuable when seeking
the perfect set-up for personal riding style or track
conditions.
Single-sided swingarm
The dual construction technique used for the single-sided
swingarm sees the main operational components use
individual aluminium castings so as to ensure strength
around the pivot points, wheel hub and suspension
links, with fabricated aluminium sections used to
complete the construction into a single, beautifully
engineered component. The 848 swingarm is colour finished
in natural aluminium while both 1198, 1198 S and 1098
R swingarms are in black.
Superbike Control
Race-bred brakes
With motorcycles as capable as the new Ducati Superbikes,
superior braking power is fundamental.
The lightweight 848 features progressive and consistent
race-bred braking performance as standard equipment
with a tried and tested formula that includes twin
radially mounted Brembo calipers each with quadruple
32mm pistons gripping 320mm discs.
The 1198, 1198 S and 1098 R uses Brembo’s powerful
Monobloc caliper racing technology. Machined from
a single piece of alloy, the calipers achieve a higher
rigidity and resistance to distortion during extreme
braking. The resulting increase in hydraulic efficiency
not only delivers incredible braking power, but also
provides an enhanced and precise ‘feel’
at the brake lever. The twin Monobloc calipers each
have quadruple 34mm pistons that grip huge 330mm discs
to help achieve spectacular brake performance. The
weight of the discs has been kept to a minimum by
employing racing-style narrow braking surfaces.
Super lightweight wheels
The lightweight front wheels of the 848, 1198 and
1198 S and 1098 R substantially reduces the moment
of inertia, enabling a faster change of direction
and enhanced acceleration and braking performances.
The construction of the rear wheels are equally as
impressive with considerable weight savings over traditional
Ducati single-sided swingarm fitments.
The 848 is equipped with Y-shaped, 5-spoke wheels
which are finished in black while the 1198 rides on
new style 10-spoke wheels finished in a subtle graphite
grey. As usual, the 1198 S goes to the next level
by rolling out on the new 7-spoke GP replica wheels.
These beautifully lightweight, forged-aluminium, machine-finished
wheels are colour-matched to the Trellis frame in
a sophisticated bronze. Lightweight Marchesini Y-shaped,
5-spoke wheels created from forged then machined alloy
and finished in ‘racing gold’ are used
for the 1098 R, and a matte black finish selected
to contrast against the special livery of the 1098
R Bayliss.
While the 848 uses Pirelli Dragon Supercorsa PRO
120/70 ZR17 front and 180/55 ZR17 rear tyres, the
1198, 1198 S and 1098 R models are fitted with Pirelli
Diablo Supercorsa SC at 120/70 ZR17 for the front
fitment and 190/55 ZR17 for the rear. These tyres
provide shoulder areas designed to maximize contact
patch area and length and carcass specially designed
for stiffness under heavy braking and precision during
high speed cornering.
Magnesium subframe
Producing a front subframe in magnesium underlines
the attention to weight-saving detail. Its construction
provides secure support for the headlamp, instruments
and fairing and the weight-saving around this high,
forward position contributes considerably to overall
‘feel’ and control of the machine.
Aerodynamic bodywork
Carefully designed for aerodynamic efficiency and
to hug the sleek lines of the chassis, the 848, 1198
and 1098 R bodywork enables the rider to blend effortlessly
into the race-oriented riding position.
Its race-developed fairing design ensures perfect
integration with the cooling system by providing efficient
flow through the advanced, large surface area coolant
radiator, which is assisted by lightweight, high flow
electric fan assemblies and oil coolers. Aerodynamically
shaped air ducts positioned just below the headlamps
are precisely calculated to provide ample air delivery
to the pressurised airbox.
The lightweight bodywork contributes considerably
to overall performance by reducing weight, protecting
the Testastretta Evoluzione engine’s power output,
and assisting the rider to effortlessly ‘tuck
in’ from the wind stream and reduce drag to
achieve maximum straight-line track speeds.
Superbike Electronics and Innovation
Instrumentation
This pure racing digital instrumentation originating
from Ducati’s MotoGP project, has no switches
or buttons to compromise its clean, minimalist lines.
Instead, information additional to the default read-outs
is managed from the left-hand handlebar-mounted switch
gear, allowing the rider to scroll through and select
from various menus. The display, which now has a bright
white LED back lighting for the 1198 and 1198 S, presents
rpm and speed, with the former displayed across the
screen in a progressive bar graph. Optionally, the
rpm and speed can be displayed in numeric values.
Additionally, it displays lap times, DTC level selected
(if activated on 1198 S and 1098 R) time, air temperature,
coolant temperature, battery voltage, two trips and
a trip that automatically starts as the fuel system
goes onto reserve. Warning lights illuminate to signify
neutral, turn signals, high-beam, rev-limit, low oil
pressure, fuel reserve, DTC intervention (if activated
on 1198 S and 1098 R) and scheduled maintenance. The
instrument display is also used as the control panels
for the DDA and DTC systems as well as listing lap
times recorded by using the high-beam flash button
as a stopwatch.
Traction control
For the first time ever on a Ducati production motorcycle,
a true competition-level traction control system for
the road comes integrated into the 1198 S and 1098
R electronics as standard equipment. The Ducati Traction
Control (DTC) system further underlines Ducati’s
technology flow from racing to production and demonstrates
how solutions developed for the track can be applied
to enhance safety on the road.
DTC uses the same software logic developed and used
by Ducati Corse for their world championship winning
MotoGP and World Superbike motorcycles and offers
a choice of eight settings developed by their professional
test riders and racers.
Accessible from the left-hand switchgear and displayed
on the digital instrumentation, the system offers
a choice of eight profiles. Each one has been programmed
with a wheel-spin tolerance matched to progressive
riding levels of skill graded from one to eight. While
level eight administers a confidence-building, high
level of interaction from the system by activating
upon the slightest amount of wheel-spin, level one
offers a much higher tolerance and so much less intervention
for highly competent riders. When the level is selected
and DTC activated, the level is displayed on the instrumentation.
When the profile that best suits the combination
of road or track conditions and riding style has been
selected and the DTC system activated, front and rear
wheel sensors compare speed differential to sense
when rear traction is being broken (wheel-spin). High
speed software then makes instant electronic adjustment
to the fuel injection, taking immediate control over
power output so as to restore traction at the rear
wheel. A warning light is displayed during DTC interaction.
As soon as the system recognises the return of equal
wheel speeds, it re-establishes normal power delivery.
In this way, DTC provides a considerable increase
in safety during mid-corner acceleration.
The DTC system is supplied as standard equipment
on the 1198 S and 1098 R models.
Data acquisition
The Ducati Data Analyser (DDA) - complete with PC
software, a USB-ready data retrieval card and instructions
- evaluates the performances of the bike and its rider,
and make comparisons between various channels of information.
The DDA is available for the 848 and 1198 from Ducati
Accessories, and is supplied as standard equipment
on the 1198 S and 1098 R models.
Normally only available on race bikes, DDA records
numerous channels of data including throttle opening,
vehicle speed, engine rpm, engine temperature, distance
travelled, laps and lap times. The system also automatically
calculates engine rpm and vehicle speed data so as
to display gear selection as an extra channel of information.
An additional channel of information is now dedicated
to recording the DTC index which can then be viewed
as a graphic trace and indicates the amount of DTC
interaction during wheel-spin. At the end of a ride
or track session, an upgraded 4mb of data can be downloaded
to a PC ready to compare, analyse and get an inside
view of the performance of the rider and motorcycle.
Data can be analysed in graphic form with options
to zoom into detail of specific sections. Dragging
a trace along a timeline to reveal individual values
of the above listed channels enables the user to analyse
performance in the same way that data technicians
can in factory teams. The latest version software
is now compatible with Windows Vista™ and allows
data to be compared with that from a completely separate
session and for pages of data to be printed off easily.
Lights and indicators
The horizontal twin headlamps, a signature Ducati
style from the iconic 916, have been modernised with
the latest lighting technology. Two polyellipsoidal
units light the way with a powerful beam while maintaining
an aggressive look to the front of the machine in
pure Ducati Superbike tradition. The units used on
the 1198 and 1098 R now save over 0.5kg (1.2lb) over
previous versions, reducing weight from a crucial
high frontal area which enhances the overall vehicle
handling and all-important ‘feel’ of the
front-end.
The rear light employs a specially designed strip
of LEDs enhanced by a high diffusion lens shaped into
the sleek lines of the tailpiece. The same LEDs are
intensified for brake lights.
The directional indicators also use the latest in
LED technology for illumination. The frontal indicators
are beautifully integrated into the rear view mirrors
and, for the 1198, 1198 S and 1098 R, now come with
an optional spacer kit enabling an extension of 30mm
over the standard mirror stem length.
