As is usually the case with performance-driven KTM, the overall design focus was on making the 790 Duke compact and lightweight. This started with the all-new 799cc parallel twin. It gets a lightweight, one-piece forged crankshaft with a 75-degree crankpin offset for an uneven 435-degree firing order, giving the 790 a V-twin sound and personality familiar with the Duke family. Forged pistons and connecting rods help with vibration and weight reduction, as do the DLC-coated finger followers, smaller cam lobes, and a secondary balancer shaft operated by the exhaust cam. Output is 95.1 hp at 9,200 rpm and 58.2 pound-feet of torque at 7,900 rpm on the Cycle World dyno; by comparison, the Yamaha MT-09 produced 105.4 hp at 9,980 and 60.5 pound-feet of torque at 8,460 rpm. What the dyno numbers don't convey is how free-revving the 790 is.
