848 reasons to spend more money....
THE NEW DUCATI SUPERBIKE
The Superbike family for 2008 features two important changes: the introduction of a mid-engine size version, the light and nimble 848, and the extreme racing 1098 R version that will take part in the 2008 World Superbike Championship.
The priority in every step of the new Ducati Superbike development has been performance first. Every system, every detail and every component has been studied, pared down to its essence and performance increased to the maximum. If it didn't make our Superbike lighter, faster or deliver quicker lap times, it wasn't considered. The 848 and 1098 are the lightest, fastest stopping, quickest lapping Ducati Superbikes in history. For the first time Ducati MotoGP and World Superbike technology have been combined to create premier sport bikes. The results are stunning.

DUCATI 848 - As agile and light as a Supersport, as powerful as a Superbike
The new 848 enjoys all the performance advancements of the entire Superbike family, while adding its own innovations to redefine the middleweight sport bike class.
The words 'agile' and 'refined' aptly describe the 848. At 168kg (369lbs) the 848 is an amazing 20kg (44lbs) lighter than its predecessor, and a significant 5kg (11lbs) lighter than its larger capacity brother, the 1098.
The highly advanced 848 engine uses an improved method of engine case production in which cases are vacuum die-cast formed. While providing significant weight savings of more than 3kg (6.5lbs), this method also ensures consistent wall thickness and increased strength. Further refinements include a sophisticated wet clutch that offers 1kg (2.2lbs) less weight, a much higher service life, improved clutch feel and quiet operation.
With the first twist of the wrist, the powerful rush of the Testastretta Evoluzione engine confirms that the rules have changed. The 848's 134hp is not only 30% more powerful than its predecessor, but it provides a power-to-weight ratio even better than the potent 999.
The new engine
The new 848 Testastretta Evoluzione engine becomes the benchmark for the middleweight sportbike category, benefiting from all the experience accumulated with the larger engine on the 1098. It successfully adopts the same design guidelines and the same compact cylinder and cylinder head layout, but introduces for the first time ever an innovative solution for the crankcase, which has been designed with a further weight reduction for this advanced engine in mind. The overall layout of this engine integrates a series of avant-guard solutions, confirming the close links with the experience of Ducati's racing department.
The 849cc engine has bore and stroke values of 94mm and 61.2mm respectively, which produce a ratio that is only slightly inferior to the 1098 (1.54 compared with 1.61), while maintaining the highly 'over-square' layout typical of racing engines.
Power output is an impressive 134hp (98.5kW) at 10,000 rpm and maximum torque is 9.8kgm (96Nm) at 8250 rpm. The power and torque values confirm the high performance level of this engine, especially when compared to its predecessor, the Testastretta-engined 749.
The cylinder head has been modified in line with the characteristic bore and stroke of the engine in order to optimize the fluid dynamics of the intake (straight and plunging) and exhaust ducts and combustion chamber. The compression ratio is 12:1.
The valve angle is the same as the 1098 engine and diameter is 39.5mm for the inlet valve and 32mm for the exhaust. The technology used sees the application of a bi-metallic alloy that combines increased lightness with resistance and reliability required for these particular components. The desmodromic control system has also been designed with the weight and the inertia of the new components in mind, allowing extremely efficient valve lift during intake and exhaust phases. The excellent results achieved are confirmed by the engine's power figures, producing outstanding performance thanks also to the use of MotoGP-derived elliptical throttle bodies, which have been fitted to the 1098 engine.
The design of a dedicated elliptical throttle body for the 848 demonstrates the attention that Borgo Panigale engineers have devoted to the development of the Superbike range. The cross-section is reduced from the 60 sq. mm of the 1098 to 56 sq. mm so as to optimize fluid dynamics at every engine speed.
Just like on the 1098, the new cylinder heads benefit from fewer components and include magnesium covers.
For the first time ever, this Testastretta Evoluzione engine sees the introduction of a special technology for the construction of the engine crankcase: Vacural? casting. This is a forced vacuum die casting method that allows jet characteristics to be improved thanks to the absence of porosity, gas inclusion and oxidation. This allows extremely high measurement precision and greater ductility for aluminum alloy. Designers have been able to harness the benefits of this innovative process by redefining the shape and the wall thickness of the new crankcase by means of FEA (Finite Element Analysis) checks, which allowed the required reliability standards to be achieved, while simultaneously obtaining a significant weight saving of 3.5kg.
The 848 engine is fitted with a silent modular wet clutch, characterized by an exceptional resistance to wear that will lead to superior duration. This solution makes a useful contribution to weight saving, estimated to be around 1.6kg, which is also due to the use of a different type of clutch cover.
The high power figures achieved by this engine also come from the use of the same type of oil cooler and coolant radiator as the 1098's engine, with an increased surface area assisted by lightweight, high flow electric fan assemblies.
Finally, the 848's exhaust system follows the same layout and uses the same innovative technology as the 1098. The system terminates with Ducati's trademark twin under-seat silencers, delivering the unmistakable signature sound of the big bore 90° L-Twin.
This power unit, just like all the other Ducati engines, has been designed to comply with Euro 3 exhaust emission norms.
Developed in cooperation with Ducati Corse, the 848 Trellis frame has a simplified tube layout featuring main section tubes increased in diameter from 28mm to 34mm, while being reduced in thickness from 2mm to 1.5mm. The result is a 14% increase in rigidity and a weight saving of 1.5kg (3.3lbs).
The 848, as all the Superbike family, is equipped with a unique single-sided swingarm. The engineers were encouraged to re-think the construction technique of this element. The solution was to produce the main operational components using individual aluminum castings so as to ensure strength around the pivot points, wheel hub and suspension links, with fabricated aluminum sections used to complete the construction into a single, beautifully engineered component.
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 848, the same as the 1098.
At the front the new 848 is equipped with fully adjustable 43mm Showa forks with radial mounts. This type of front suspension is professionally track-tuned and offers superior road holding, delivers superior feedback, and helps every rider to be more confident and in control.
Brembo Monobloc calipers
The 848 brake system is characterized by M4 calipers using four 32mm pistons and two radial mounted pads. Matched to the calipers are two 320mm discs and the combination of these elements achieves spectacular braking power.
Super lightweight wheels
The new 848 also benefits from lightweight Marchesini Y-shaped spoke wheels. The weight saving of 250gr achieved on the front wheel substantially reduces the moment of inertia and enhances the 848'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. Finally a 5.50" wheel fitted with a 180/55 tire guarantees the maximum agility at the rear.
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 Analyzer (DDA), which includes PC software, a USB-ready data retrieval card and instructions, owners are ready to review and analyze 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 traveled, 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, analyze and get an inside view of you and your 1098's performance.
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 are able to do in factory teams.
