Back to the future for Ducati 1098

And, in a late development, the machine is booked to make an appearance at the November 17-19 Sydney Motorcycle Show.

While the styling of the 1098 hails back to the firm's ultra-successful Tamburini-designed 916, the machine is all new and, with 160 horses at 9750rpm on the spec sheet, claims to be the most powerful V-twin in the world. The powerplant sticks with desmodromic valve actuation and claims a healthy 12.5kg-m of torque at 8000rpm.

There are numerous high-end gadgets on the machine, such as the all-digital dash, which is controlled by handlebar-mounted switches and which the company claims is lifted direct from the Desmosedici GP7.

The chassis has a number of new features, such as Brembo's latest radial-mounted monobloc brakes on the front, while the rear swingarm remains a single-side affair, but with the chain threaded through the arm.

Claimed dry weight for the package (excluding battery) is a mere 173 kilos, which should make for very lively performance.

Two versions are being offered when the machine is shipped over the coming months: a 'plain' 1098 plus an S version with upgraded front suspension (a switch from Showa to Ohlins) and some other goodies.

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 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 value far greater than the sum of all its parts.

Trellis frame Developed in cooperation with Ducati Corse, the 1098 Trellis frame has been designed with 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).

Single-sided swingarm
The engineers were encouraged to re-think the construction technique of the 1098's unique single-sided swingarm. The solution was to produce the main operational components using 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.

Rear suspension
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 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 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.

Front suspension
The fully adjustable 43mm Showa forks with a 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.
