EICMA: Ducati 1098 and 1098S
Designed by the racetrack: The
look and stance of the 1098 were designed by the combination
of race track technology, track-derived components and Ducati
heritage.
Ducati 1098
Carefully designed not only for aerodynamic efficiency but also
to hug the sleek lines of the chassis, the 1098 enables the rider
to blend effortlessly into the race-oriented riding position.
The racing spirit takes form. Thanks to the forward thinking
design and changeability of most components, the 1098 can quickly
be transformed into a real race bike.
The 1098 is the first production motorcycle to have the amazing
stopping power of Brembo Monobloc brakes, the first to have a
data acquisition system integrated as standard equipment and
the first to use an ingenious construction method for its weight-saving
single-sided swingarm. More 'firsts' for a road-going Ducati
include the direct application of MotoGP technology, like the
power producing GP6-derived elliptical throttle bodies and the
use of the information-rich instrumentation originally developed
for the new Desmosedici GP7.
Ducati 1098S
The 1098 has the soul of a race bike, pure and simple. The huge
104mm bore and all-new cylinder head design unite to produce
an awesome 160hp and an arm-wrenching 90+ lb-ft of torque. Developed
together with Ducati Corse, the 1098 is a masterpiece of incredible
performance and innovation.
POWER
The 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 the last 15 years is the result of continual commitment
to twin-cylinder technology and the 1098 Testastretta Evoluzione,
one of the most powerful twin-cylinder production engines in
history, is a fitting reward to our engineers' continued ingenuity.
The 1098 engine is immediately recognisable by its completely
new compact cylinders and cylinder heads. Other 1098 innovations
and revisions are less obvious as they reside inside the Evoluzione's
engine cases, but whether external or internal, every new development
was conceived to create a lighter, more efficient, more powerful
and ultra-compact engine for the new generation of Ducati Superbikes.
The 1098 capacity is a result of a significant increase in the
bore and stroke of the Evoluzione motor. Highly 'over-square',
it now sports a big 104mm bore and a relatively short 64.7mm
stroke. To optimise the benefits of the new, big Ducati Twin,
the cylinder heads have been completely redesigned and, when
combined with advanced MotoGP induction technology, enable even
the standard specification 1098 to produce more power than the
previous extreme Testastretta 'R' engine.
Ducati 1098S
The Evoluzione features a reduction in the angle between intake
and exhaust valves allowing highly efficient, straight intake
ducts and newly shaped combustion chambers that contain racing
size 'R' valves (42mm inlet, 34mm exhaust), operated by radical
'R' derived camshafts. The new cylinder heads also benefit from
fewer components and include magnesium covers to achieve a staggering
weight-saving of over 3kg (6.5+lbs).
After optimising the Evoluzione cylinder heads, engineers then
focussed upon releasing the potential of the new design by feeding
them with MotoGP-derived elliptical throttle bodies. With a 30%
increase in air flow over conventional throttle bodies, the new
elliptical shape contributes an incredible 5hp increase to the
record-breaking motor.
The Testastretta Evoluzione is the lightest Ducati Superbike
engine ever, thanks to close scrutiny of every engine component.
A total of 5kg (11.1lbs) has been saved by reducing the weight
of many components, including transmission gears and the gear
selector drum as well as the oil pump and primary gears.
The Testastretta Evoluzione's increase in power is protected
by a highly efficient oil cooler with increased surface area
and an advanced coolant radiator assisted by lightweight, high
flow electric fan assemblies. The compact and intricate design
of the cooling system integrates perfectly with the 1098's wind-cheating
aerodynamics and sleek lines.
Finally, the 1098 is complemented by an all-new exhaust system.
Significantly lighter, it has been engineered with a power-increasing
symmetrical 2-1-2 layout that uses 52mm-57mm diameter tubing
with wall thickness reduced by 30% to 0.8mm (.030in). The system
terminates with Ducati's trademark twin under-seat silencers,
delivering that unmistakable signature sound of the big bore
90° L-Twin.
CHASSIS
The 1098's chassis and suspension have received the same
detailed study and 'performance-first' priority approach. The
goal was to achieve considerable weight saving while building
in strength and rigidity to manage the new high-powered Testastretta
Evoluzione engine. Each and every component not only contributes
to achieving superior road holding and stability, but when assembled,
become a system with a value far greater than the sum of all
its parts.
Ducati 1098S
Highlighting the way in which individual components are influenced
by each other, the new lightweight Trellis frame and single-sided
swingarm have enabled a more compact and further weight-saving
rear suspension linkage system to be used featuring 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 1098 and an incredible Öhlins shock for the 1098
S. A vitally important feature of the 1098's rear suspension
system is the ability to adjust rear ride height independent
of spring pre-load and other suspension settings, critical when
seeking the perfect set-up for personal riding style or track
conditions.
The fully adjustable 43mm Showa forks with special low friction
Titanium Oxide-treated sliders on the 1098, and spectacular 43mm
Öhlins with low friction Titanium Nitride sliders on the
1098 S, both feature radial Monobloc caliper mountings. The unique
look of these mountings further underlines the no-compromise
racing specification of the 1098. Both front suspension solutions
are professionally track-tuned and offer superior road holding,
deliver superior feedback, and help every rider to be more confident
and in control. That control is further enhanced with the use
of a Sachs steering damper for the 1098 and for the S version
the Öhlins package is completed with a control-enhancing
fully-adjustable steering damper.
Both the 1098 and the 1098 S use Brembo's Monobloc caliper racing
technology. The M4.34 caliper uses four 34mm pistons and
two large surface pads for maximum stopping power. Calipers are
machined from a single piece of alloy, vs. the bolt-together
construction of conventional calipers. The Monobloc design has
much higher rigidity and resistance to distortion during extreme
braking, and therefore gives a much more precise feel at the
brake lever. The 1098 also introduces for the first time on a
Ducati, big 330mm discs which, when matched to the Monobloc calipers,
achieve spectacular braking power. Despite the larger diameter,
their weight has not increased due to the use of racing-style
narrow braking surfaces. The use of Monobloc technology combined
with the legendary stability of Ducati's Trellis frame and the
1098's overall weight savings has made world championship level
brake performance available for the road.
The weight saving of 250gr achieved on the front wheel substantially
reduces the moment of inertia and enhances the 1098's change
of direction and braking performance. The rear wheel is just
as impressive with a complete redesign for its single-sided swingarm
application that has resulted in a reduction of over 1kg compared
with traditional Ducati single-sided swingarm fitments. Both
the 1098 and 1098 S benefit from the lightweight Marchesini Y-shaped
spoke wheels, but the 'S' goes even further by using machine
finished forged-aluminium, a special process normally reserved
for the production of race wheels. Another first for Ducati is
the mounting of 190/55 rear tyres, our widest ever, and the new
standard for traction and control.
Superbike Electronics
Desmosedici-style digital instrumentation is taken from Ducati's
MotoGP GP7 project. This pure racing, minimalist solution has
no switches or buttons to compromise its clean lines.
Instead, information additional to the default read-outs is managed
by handlebar-mounted switch gear, allowing the rider to scroll
through and select from various menus. The default read-out 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. The instrument display also doubles
as a control panel for the activation of the data acquisition
system as well as listing lap times recorded by using the high-beam
flash button as a stopwatch.
With the purchase of the Ducati Data Analyser (DDA), which includes
PC software, a USB-ready data retrieval card and instructions,
owners are ready to review and analyse the performance of the
1098 and its rider, and make comparisons between various channels
of information. The DDA is available from Ducati Accessories,
and is supplied as standard equipment on the 1098 S and on the
new 1098 R.
Normally used on race bikes only, the system 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 also display gear selection as an additional
channel of information. At the end of a ride or track session,
up to 2mb (approximately 3.5 hours) of data can be downloaded
to your PC ready to compare, analyse and get an inside view of
you and your 1098's performance.
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
are able to do in factory teams.
