Ducati Spring Diavel

Diavel is a new model, it nevertheless is comprised of many familiar Ducati components, the most prominent of which is its Testastretta 11° engine. This grunty, high-performance 1198.4cc 90-degree Twin (aka L-Twin) is sourced from the current model Multistrada. And with the exception of a new exhaust, it remains largely unchanged as used in the Diavel.
According to Giulio Malagoli, technical director on the Diavel project, the new Duc’s exhaust system, consisting of equal-length 58mm cross-section exhaust headers and dual stacked shorty megaphone cans, is the primary contributor to a 12 hp and 6.5 ft-lb increase over the Multi’s 150 hp and 87.5 ft-lbs. The Diavel’s airbox is marginally larger than the Mulitstrada’s, but the negligible increase in volume isn’t essential to power gains and is more a matter of technical needs. Additional revisions include different cam timing, as well as reworked intake and exhaust ports.
During the Diavel’s tech briefing Ducati displayed a dyno graph overlay with power and torque results for the 1198 superbike, Multistrada and Diavel.
