With customizable ride modes and the new 1,262cc Testastretta DVT motor, the Diavel S is an incredibly powerful beast, but not wild or unwieldy. It hammered out 138.5 hp and 85.4 pound-feet of torque on the dyno, its massive emphasis on peak horsepower instead of torque a clear philosophical difference in Italian versus American engine tuning. Desmodromic Variable Timing (DVT) changes cam timing to help the engine deliver clean, responsive, broad power no matter the revs. Reduced valve overlap makes for smooth, crisp throttle response at the low end, as well as reduced emissions and increased torque. As revs climb, overlap is increased, letting the engine breathe more freely for equally crisp response and more horsepower toward the top of the rpm range. The Diavel's previous 1,198cc engine was lurchy at lower rpm, surging even with steady throttle and constantly spurred the rider to bring it into a higher rev range where operation was smoother. But the new engine's smooth and linear power delivery makes it far better used in a more cruiser-esque model, giving you all the power when you want it, but only when you want it.
