2010 The Ducati 848 is a 849 cc (51.8 cu in)
While most of the chassis components are identical to the 1098/1198, the motor was an all new design in 2008. Producing roughly 116 hp at the rear wheel it out performs the revered Ducati 916 that had a hard time producing more than 100hp and even the upgraded Ducati 998 that produced 110 hp at the rear wheel. The "Testastretta Evoluzione" uses a 94 x 61.2mm bore and stroke for 849cc of displacement despite the bikes moniker of 848. The motor casings were constructed using a new vacuum die-casting method called Vacural that helps the engine weigh seven lbs less than the Ducati 749. The intake valves were increased 2.5mm from the Ducati 749 numbers to 39.5mm. The exhaust valves were enlarged 1.5mm to 32mm. The valve angles are identical to the Ducati 1098. The bike uses a pair of elliptical shaped 56mm throttle bodies fashioned after MotoGP designs.
The 2011 Ducati 848 Evo featured minor changes to the engine, including new Marelli throttle bodies, revised cylinder heads with straighter intake ports and reshaped combustion chambers. Ducati claimed these changes would result in a 6-hp increase, bringing output to 140 measured at the crank, however Cycle World Magazines first dyno test of the engine showed a mere 1.6 hp increase over the previous motor
