Ducati 1198SP Interesting choice of Ducati fans
That is best information for fans Ducati
Like the standard 1198, the 1198 SP arrives equipped with Ducati Traction Control (DTC), Ducati Quick Shifter (DQS) and Ducati Data Analyser (DDA), but the SP also features Ohlins TTX rear suspension, slipper clutch and lightweight aluminum fuel tank.
The application of DTC to the 1198 SP underlines Ducati's intention to broaden the use of tried and tested race-derived electronics to its high-powered range, while the introduction of DQS marks the first time in history that "quick-shift" electronics have been fitted to a production Ducati.
The 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 share the reward for that commitment with World Championship- winning technologies constantly flowing from the factory race team into production engines.
The incredible 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 @ 8,000 rpm. The 1198 SP 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 optimized 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 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.
To keep Ducati's 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 SP features 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 Ducati's trademark twin under-seat silencers, delivering that unmistakable signature sound of the big bore Desmo 90° L-Twin.
1198 SP: Pure Race Performance
Stunning 'SP' performance: the 168kg (370.3lb) (dry weight) 1198 SP creates a dream package by taking everything that the 1198 model has, including DTC, DDA and the new DQS systems, and adding top-of-the-range Öhlins suspension, lightweight chassis components, a lightweight factory team-style aluminum fuel tank and slipper clutch.
The high performance, fully adjustable 43mm Öhlins forks, which sport low friction titanium nitride-treated fork sliders, respond effortlessly to every imperfection in the tarmac.
Beyond their advanced engineering solutions, one of the most important characteristics of Öhlins forks is their ability to communicate the condition and quality of the tyre-to-road contact patch, a feature that puts every rider in superior control.
The suspension set-up at the rear is complemented with a fully adjustable Öhlins TTX rear shock equipped with a ride enhancing top-out spring and mounted to a single-sided swingarm for outstanding drive and traction. The front-to-rear Öhlins package is completed with a control-enhancing adjustable steering damper.
On any sport or race bike, the most effective area to reduce weight is its 'unsprung weight'. These are components like tires, brakes and wheels. Lighter wheels have a lower 'moment of inertia' that is beneficial with every direction change and application of the brakes.
The 1198 SP addresses this important area by mounting 7-spoke Marchesini forged and machined wheels. Both front and rear are super lightweight and their benefit is immediately apparent. The weight saving is further enhanced with the application of a carbon fiber front fender.
The 1198 SP weighs in at 1kg (2.2lb) less than the 2010 1198 S thanks to the beautifully made lightweight fuel tank, which also boosts the bike's fuel capacity by 2.5 liters (0.66 US gal) to 18 liters (4.75 US gal).
The tank is formed in 2mm thick aluminum, brush finished and then painted and clear-coated to create a racing stripe of natural aluminum that accentuates the factory race tank feel.
The 1198 SP is supplied with the Ducati Data Analysis (DDA), Ducati Traction Control (DTC) and Ducati Quick Shift (DQS) systems as standard equipment.
The DDA package 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 2011 1198 SP is available in two color schemes. The traditional Ducati red is now supported by a new diamond black and completed with red Trellis frames and black wheels with signature red pin-striping.
Ducati 1198 / 1198SP Features:
Engineered by the stopwatch
The 1198 SP Superbikes 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 Ducati's 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 SP 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 Ducati's lightest frame solutions ever. Adding style to performance, both schemes of the 1198 SP are finished in red.
Front Suspension
The 1198 features spectacular 43mm Öhlins with low friction titanium nitride-treated sliders are used on the 1198 SP. The 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 an incredible Öhlins unit for the 1198 SP with TTX twin tube technology providing totally separate damping adjustment in compression and rebound.
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 aluminium castings so as to ensure strength around the pivot points, wheel hub and suspension links, while lightweight, fabricated aluminium sections are used to complete the construction into a single, beautifully engineered component. The 1198 SP all have single- sided swingarms finished in black.
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 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.
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 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 motorcycle's 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 and 1198 SP 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 both the 1198 and 1198 SP 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 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 engine's 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.
