More powerful, lighter and safer
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.
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
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.
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’ .
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.
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.
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.
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.
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.
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
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.
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.
