The 1198 Testastretta DS motor may be the star of the show, but it isn’t exactly new; you’ll find it in other Ducati models, including the Monster 1200 and the Multistrada. Breathing through elliptical Ride-by-Wire throttle bodies, the new Testastretta tweaks fuel injector positioning and adds a higher compression ratio for enhanced combustion efficiency. Ducati’s engine management systems make the fierce 1198 Superbike power plant more user-friendly by slightly lessening horsepower and enhancing mid-range and smoothness. The claimed 162 peak horsepower of the previous version remains, but Ducati says the torque peak has been moved slightly lower and broadened, thus boosting the bottom end for more real-world rideability. As before, the Diavel has three customizable riding modes: Sport, Touring and Urban, each of which can be selected to moderate power for conditions. Sport serves up the unrestricted, 162 hp full monty, while Touring softens that a touch, and Urban cuts max power by 40 percent, doling out a more relaxed ride at a ‘mere’ 100hp.
