DUCATI THE SUPERBIKE

DUCATI 848

LIGHTWEIGHT MOVES - HEAVYWEIGHT PUNCH

The new 848 enjoys all the performance advancements of the entire Superbike family, while adding its own innovations to redefine the middleweight sport bike class.

The words 'agile' and 'refined' aptly describe the 848. At 369 pounds (168 kilograms) the 848 is an amazing 44 pounds (20 kilograms) lighter than its predecessor, and a significant 11 pounds (5 kilograms) lighter than its larger capacity brother, the 1098.

The highly advanced 848 engine uses an improved method of engine case production in which cases are vacuum die-cast formed. While providing significant weight savings of more than 6.5 pounds (3 kilograms), this method also ensures consistent wall thickness and increased strength. Further refinements include a sophisticated wet clutch that offers 2.2 pounds (1 kilogram) less weight, a much higher service life, improved clutch feel and quiet operation.

With the first twist of the wrist, the powerful rush of the Testastretta Evoluzione engine confirms that the rules have changed. The 848's 134 horsepower is not only 30 percent more powerful than its predecessor, but it provides a power-to-weight ratio even better than the potent 999.
