Performance And Review Ducati 848 Evo





When you see Ducati 848 Evo maybe you think that is very difficult but
Ducati is very easy
For 2011, the 848 features N "EVO" treatment to its popular Testastretta engine and chassis. This powerful L-Twin engine is up 6 horspower to 140 and has 72.3 lb-ft torque, and is installed in the light 168 kg chassis, one thats been proven itself over and over on the 848 since its introduction in 2008.

The bike contains the usual features that makes thousands of motorcyclist eagerly seek Ducatis famed Superbike: twin under-seat silencers, single-sided swingarm, Trellis frame, race bodywork and steering damper.

The 2011 848EVO maintains the traditional colour of Ducati red with red frame and black wheels and introduces the new "dark stealth" with racing black frame and black wheels.

Ducati 848EVO Features

The 848 Testastretta Evoluzione engine:

The new 848EVO is powered by a liquid cooled, L-Twin, Desmodromic engine that produces 140hp (103kW) @ 10,500rpm and a high-accelerating 72.3lb-ft (10kgm) of torque @ 9,750rpm.
The 94mm x 61.2mm bore and stroke breathes through 4 valves per cylinder fed by totally revised inlet port shapes and racing-style elliptical throttle bodies, which are now increased in size from an equivalent diameter of 56mm to 60mm.
A brand new piston crown and combustion chamber shape improve burn efficiency and increase the compression ratio from 12:1 to a power-enhancing 13.2:1 while new performance-driven camshafts provide 13mm of valve-lift compared with 11.5mm and an inlet duration increase from 253° to 257°.

These incredible valve performances are made possible because of Ducatis unique Desmodromic system, where valve closure is activated mechanically. At high rpm it would be almost impossible for the valve to follow the steep closure profile of the cam lobe if it were relying upon a normal valve spring. With the Desmo system, the valve is closed mechanically with the same accuracy as it is opened, enabling steep cam profiles and radical cam timings. This system is used on every single Ducati motorcycle including their world-beating Superbike and Desmosedici MotoGP bikes.
Electronically injected and ignited by Marelli, the super-efficient power unit then exhausts through a lightweight 2-1-2 system equipped with a catalytic converter and up-rated to twin lambda probes for smooth mapping and Euro3 conformity. Terminating in Ducatis trademark twin under-seat silencers, the system delivers that unmistakable signature sound of the Desmo 90° L-Twin.

The highly advanced 848 engine was the first Ducati Superbike to introduce vacuum die-cast crankcases, formed using Vacural® technology, a process that achieves a significant weight saving and ensures consistent wall thickness and increased strength. For 2011 this impressively lightweight engine has its outer-cases finished in black.
The 848EVO engine is a fitting reward to Ducatis ingenuity and a clear result of the continual attention to detail and development of their twin-cylinder technology.

Having more experience and success with twin-cylinder high performance engines than any other manufacturer, the L-Twin configuration remains central to Ducatis philosophy of motorcycling. This experience, plus constant investment in quality by design, advanced materials and engineering techniques, has enabled 12,000km (7,500 miles) between service intervals, making Ducati ownership easy and enjoyable.
