2008 Ducati 1098S

2008 Ducati 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.

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.

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.

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.

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.
