Ducati shows Multistrada 1100 and 1100S

The camshafts are supported on oil pressurized plain bearings, which reduce the overall dimensions, the weight, and the number of moving parts, while also improving heat dispersal. The new configuration also puts the camshafts in a more direct relationship with the valves, reducing friction and stress on valve components and thus increasing reliability. In fact, although the cylinder head is more compact, it allows more space for the intake and exhaust valves, these being 45 mm and 40 mm in diameter respectively. Further innovations include valve seats made of beryllium bronze, a technologically advanced material that affords better heat dispersal and wear-resistance and thus maintains valve clearances more accurately over a longer period of time.

To guarantee high mid-range performance, the crankshaft, cylinders and pistons have been designed to obtain a bore and stroke value of 98 mm and 71.5 mm respectively. The pistons are fitted with nitrided steel rings, which afford improved sealing and significantly reduce oil consumption. The connecting rods are made from a new material composition (30NiCrMo4) that has exceptional flow characteristics during forging. In cross section, the new rods are thinner side-to-side, but wider fore to aft, increasing strength and lowering weight for increased reliability and performance.

The crankshaft is of a more compact design and the oil passages have been strategically repositioned in areas less critical for its structural strength. The result is a crankshaft that is more rigid and with less flex, making for less vibration and improved reliability.

The 1100 Dual Spark engine also features a new ‘wet’ clutch that has lighter lever effort, is quieter and more modular than a dry clutch and is characterized by having exceptional wear-resistance. Thanks to an excellent compromise between performance, reliability, noise and lever effort, this clutch is ideal for sports riding and at the same time offers ensures a more progressive action and feel.

The overall look of the engine is characterized by injection-moulded timing belt covers in black, high mechanical and thermal resistance plastic. The engine covers are in a new dark grey colour.

Starting with the entire 2007 range Ducati has introduced a new maintenance programme in which servicing intervals have been extended, and less parts are required and fewer operations are performed, thus reducing the bike’s overall running costs by up to 50%.

Multistrada 1100 S

Due to its world-class suspension and componentry level, this version is for those riders who demand the ultimate in sports performance. It is based on the Multistrada 1100 but features a number of components derived from the Ducati Superbikes, including fully-adjustable Öhlins suspension and carbon fibre highlights.
