When it comes to a superb-performing superbike, the Ducati 1198 has been in the leading pack since its inception in 2009. And on Tuesday, the Italian manufacturer unveiled the 2011 Ducati 1198 (and 1198 SP) at INTERMOT in Germany.

New for 2011, the 1198 motorcycle arrives on the showroom floor with Ducati Traction Control (DTC), Ducati Quick Shifter (DQS) and Ducati Data Analyzer (DDA) as standard equipment.

Ducati says The application of DTC to the standard model 1198 underlines Ducatis intention to broaden the use of tried and tested race-derived electronics to its high-powered range, while the introduction of DQS to the 1198 marks the first time in history that "quick-shift" electronics have been fitted to a production Ducati.

The DDA package in the 1198 enables the retrieval and analysis of data collected from a previous track session or road trip and DTC monitors front and rear wheel speeds to detect rear wheel-spin under acceleration and electronically reduces engine power to restore traction.

DQS allows the throttle to remain open when changing-up through the gearbox, helping to save vital seconds in the pursuit of faster lap-times.

The 1198 was born to perform and with a colossal 97lb-ft (13.4kgm) of torque from its Testastretta Evoluzione engine and dry weight of just 171kg (377lb) it always delivers.

Its victory-driven technology comes directly from Ducatis World Championship-winning race bikes - and its evident in every detail of the bike.

Fully adjustable Showa front suspension carries radial mountings designed for the awesome stopping power generated by Brembo Monobloc callipers and 330mm discs.
Fully adjustable Showa suspension at the rear and lightweight 10-spoke wheels complete an impressive set-up. For 2011 the 1198 is available in traditional Ducati red with a racing black frame and graphite grey wheels.

The 1198 Testastretta Evoluzione Engine

The Testastretta Evoluzione engine is the crowning glory of Ducatis 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 share the reward for that commitment with World Championship- winning technologies constantly flowing from the factory race team into production engines.

The incredible 1198 (and 1198 SP) is 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 capacity by using exactly the same 106 x 67.9 bore and stroke as the factory race bike.

Volumetric efficiency through the four valves per cylinder is optimised with valve diameters at 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.

The incredible valve performances achieved are only possible because of Ducatis 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.

To keep Ducatis highly efficient Testastretta cylinder heads breathing to their full potential, the injection system uses racing size elliptical throttle bodies, which are an equivalent diameter of 63.9mm.

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 Vacural technology, a crankcase vacuum die-cast manufacturing process yielding weight reductions of 3kg (6.5lbs) compared to the first generation 1098 cases.

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 color, while the alloy outer clutch and generator covers sport a black finish.

The 1198 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.

Specifically for the track-ready 1198 SP, a dry, multiplate competition-style slipper clutch is used to reduce the destabilising effect of aggressive downshifting and to provide the fine control required during extreme corner entry on the track.

The 1198, 1198 SP 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 optimum engine mapping and Euro3 conformity. The system terminates with Ducatis trademark twin under-seat silencers, delivering that unmistakable signature sound of the big bore Desmo 90° L-Twin.

Ducati 1198 Features:

Engineered by the stopwatch

The 1198 Superbike are the product of a team of designers and engineers who have combined their Ducati MotoGP and World Superbike technologies to create the finest sportbikes in the world.

From race-level engine specifications to World Championship-winning traction control and quick- shift electronics, the results are pure excellence.

The Ducati Traction Control (DTC) system further confirms Ducatis technology flow from racing to production and demonstrates how solutions developed for the track can be applied to enhance safer performance on the road.

Designed by the race track

Ducati Superbikes are race bikes, pure and simple. Their striking aerodynamic shapes create a natural riding position, confirmed by Ducati development and factory team riders as the optimum for speed and agility.

Performance is first and foremost in every detail. Trademark Ducati features like the high tail section and compact front end combine with twin under-seat silencers and single-sided swingarm to express the sheer engineering beauty of aerodynamics and agility.

Add the Testastretta Evoluzione engines as the hearts of the machines and the result is all-out performance Ducati Superbikes that look fast even when parked.

Superbike Chassis

The 1198 chassis and suspension are the result of a performance-first priority approach to development, in which the goal is always to further reduce weight and increase strength and rigidity to manage the high-powered Testastretta Evoluzione engines.

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 Ducatis lightest frame solutions ever. Adding style to performance, the 1198 is in racing black.

Front Suspension

The 1198 features 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 SP.

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 enable 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 1198.

The system uses experience gained in MotoGP to minimize friction and reduce the risk of cavitations under extreme conditions. The 1198 and 1198 SP 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 allows the main operational components to use individual aluminum castings so as to ensure strength around the pivot points, wheel hub and suspension links, while lightweight, fabricated aluminum sections are used to complete the construction into a single, beautifully engineered component.

The 1198 and 1198 SP all have single- sided swingarms finished in black.

Race-Bred Brakes

Ducati Superbikes have always been famous for their incredible, track-derived braking performance and the 2011 model line-up is no exception.

The 1198 uses Brembos incredibly 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 callipers each have four 34mm pistons that grip huge 330mm discs on the 1198 to achieve spectacular braking performance.

Super Lightweight Wheels

The lightweight front wheels used on all Ducati Superbike models substantially reduces the moment of inertia, enabling a faster change of direction and enhanced acceleration and braking performances.

The 1198 rides on 10-spoke wheels finished in a subtle graphite grey, also by Enkei. The 1198 is fitted with Pirelli Diablo Supercorsa SP tires, at 120/70 ZR17 for the front, and 190/55 ZR17 for the rear of the 1198.

These high-performance tires have shoulder areas that maximize the contact patch and carcasses specially designed for stiffness under heavy braking and precision during high speed cornering.

This precision in tire construction enabled Ducati technicians to create extremely fine programs for the Ducati Traction Controls systems used on the 1198 and 1198 SP.

Magnesium Subframe

Producing a front subframe in magnesium underlines the attention to weight-saving detail in the Ducati Superbike range.

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 Superbike bodywork enables the rider to blend effortlessly into the correct 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 pressurized airbox.

The lightweight bodywork contributes considerably to overall performance by reducing weight, protecting the Testastretta Evoluzione engines power output, and assisting the rider to effortlessly tuck in from the wind stream and reduce drag to achieve maximum straight-line track speeds.

Instrumentation

This pure racing digital instrumentation originating from Ducatis 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 has a bright white LED back lighting 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 and 1198 SP) 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 and 1198 SP) and scheduled maintenance.

The instrument display is also used as the control panels for the DDA (supplied as standard equipment with the 1198 and 1198 SP), DTC and DQS systems as well as listing lap times recorded by using the high-beam flash button as a stopwatch.

Superbike Lights and Indicators

The horizontal twin headlamps, a signature Ducati style from the iconic 916, are 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 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, which come with an optional spacer kit enabling an extension of 30mm over the standard mirror stem length.

Ducati Quick Shift

The Ducati Quick Shift (DQS) system is the first time that a race-style electronic quick-shift has been supplied as original equipment on a production Ducati. Normally used specifically for racing, the system allows the rider to keep the throttle open when changing-up through the gearbox, helping to save vital seconds in the pursuit of faster lap-times.

The system not only saves time when changing gear, but also enables the possibility of uninterrupted air flow through the throttle bodies throughout the upward gear- changing process.

The system consists of a micro-switch built into the linkage of the gear change lever, which when actuated in the direction of selecting a higher gear, sends a signal to the main ECU.

The ECU instantly understands which gear the motorcycle is in by calculating the rpm and vehicle speed and then reads the amount of throttle opening before applying a pre-programmed cut in fuel injection and ignition measured in milliseconds.

This spilt-second electronic interruption in drive is programmed precisely to allow the next gear to be selected without having to actuate the clutch or close the throttle.

The DQS system can be deactivated by entering the control panel in the motorcycles instrumentation and is reactivated by default the next time the ignition is turned on.

As the system only functions for a matter of milliseconds, the 1198 can still be ridden using a normal gear-changing style.

Ducati Traction Control

Ducati were the first manufacturer to introduce a true competition-level traction control system on a production motorcycle and for 2011 the highly successful system is now integrated into 1198 electronics as standard equipment.

The Ducati Traction Control (DTC) system further underlines Ducatis technology flow from racing to production and demonstrates how solutions developed for the track can be applied to enhance performance 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 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, therefore, 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).

DTC then decides the best combination of two different types of instant electronic adjustment, calculated with data supplied from multiple sources.

The first soft stage of system interaction is executed by high speed software that makes instant electronic adjustment to the ignition timing, administering varying amounts of ignition retardation to reduce the engines torque.

During this initial stage of DTC interaction, up to three red lights - normally used to signify the over-rev limiter - illuminate to indicate the amount of DTC being applied.

If the DTC software detects that the first soft stage of system interaction is inadequate to control the wheel-spin, it continues to administer ignition retardation and, in addition, instructs the engine ECU to initiate a pattern of constantly increasing injection cuts until, if necessary, full injection cut.

During this second stage of interaction, all four warning lights fully illuminate to signify that DTC has also initiated injection cuts. As soon as the system recognizes the gradual return of equal wheel speeds, it incrementally re-establishes normal power delivery. This seamless interaction is key to the super-smooth operation of the system.

The real innovative thinking behind the DTC system is how the various range of sensitivity levels decide precisely how to react to excessive wheel-spin by understanding the bikes exact dynamic situation.
From slow mid-corner acceleration with considerable vehicle inclination to high speed corner exits while almost upright, this system intelligence is achieved by processing a mass of data in a matter of milliseconds.

This technology exists thanks to the thousands of laps and hours spent testing, programming and earning Ducati Corse race victories on the track. It represents just part of Ducatis latest road-bike technology and provides considerable increase in performance safety during mid-corner acceleration.

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 makes comparisons between various channels of information.

The DDA is supplied as standard equipment with the 1198 (and 1198 SP).

Normally only available on race bikes, DDA records numerous channels of data including throttle opening, vehicle speed, engine rpm, engine temperature, distance traveled, 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, analyze and get an inside view of the performance of the rider and motorcycle.

Data can be analyzed 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 analyze performance in the same way that data technicians can in factory teams.

The software allows data to be compared with that from a completely separate session and for pages of data to be printed off easily.
