Ducati Streetfighter 848 Engine

A masterpiece of Desmodromic engine design, the 848 Testastretta 11° can deliver 132 hp at 10,000 rpm and a torque of 9.5 kgm at 9,500 rpm. A direct offshoot of the Testastretta Evoluzione used on the Superbike 848EVO, it makes the most of the Testastretta 11° technology that has already proved so successful on the Multistrada and Diavel, giving awesome torque even at low revs.

With respect to the Testastretta Evoluzione the overlap angle has been reduced from 37° to 11° to ensure unbeatably fluid power delivery, a much wider power band and reduced consumption and emissions.
The Testastretta 11° maintenance schedule requires valve regulation just once every 24,000 km.

With its 132 HP and awesome torque of 9.5 Kgm (93.5Nm) at 9,500 rpm , the 848 Testastretta 11° provides pure Desmodromic performance. Radical changes to the timing diagram have allowed achievement of a full torque curve even at low revs, which considerably increases the ridability of the Steetfighter 848 and, because it remains constant throughout an extremely wide power band, ensures maximum enjoyment at high revs too.

The new Streetfighter 848 offers pure motorcycling thrills thanks to its perfect combination of 848 Testastretta 11° engine and a new Trellis frame with Superbike 848EVO-derived geometry.

Attention to weight reduction is further underlined with both cam covers and clutch outer cover cast in manesium alloy.

The Testastretta 11° engine on the Streetfighter 848 features a crankcase produced by pressure die casting under vacuum using Vacural® technology: this gives significant weight savings and ensures constant wall thickness and greater strength.

The Streetfighter 848 lightweight crankshaft assembly operates a ‘over-square' bore and stroke with 94mm pistons and 61.2mm strokes.

The Testastretta 11° engine transmits drive to a sophisticated wet clutch that is a full kilo lighter than the corresponding dry version; it is also characterised by enhanced durability, improved 'feel' and lower noise levels, making riding a real pleasure whatever the circumstances.

The massive 2-1-2 exhaust system is made from weight-saving 1mm thick steel and flows from 58mm to 63.5mm diameter pipes. The system uses two lambda probes to ensure precise fuel mapping for optimum performance and an electronic valve in the mid-section to achieve a wide spread of power.

The cannon-style, vertically stacked, brushed steel mufflers deliver the famous Ducati L-Twin sound synonymous with raw, Desmo power.
