The electronic Keihin engine management system with twin throttle valves regulates the modern electronic fuel injection system, focussing on maximum power with predictable engine characteristics and spontaneous responsiveness with controllable throttle response. The throttle body has been enlarged from 52 to 56 mm in the area of the throttle valves for the KTM 1290 SUPER DUKE R in order to optimise power development.
The engine of the KTM 1290 SUPER DUKE R originates from one of the most powerful and refined V2 power units of our times, from the engine of the KTM 1190 RC8 R superbike. KTM engineers increased the displacement of the LC8 powerplant, not simply by boring it out, but by well-balanced enlargement of both, bore and stroke. Weighing in at around 62 kg, the extremely slim four-valve unit is one of the lightest big twins in the world, yet it still develops no less than 180 hp peak power and 144 Nm maximum torque.
The responsiveness and free-revving nature of the KTM 1290 SUPER DUKE R's engine are also enhanced by the very low reciprocating weight of its crankshaft. Moreover, the flow-optimised shape of the crank webs boosts the particularly low-loss running of the crank drive, with casing evacuation improved by the use of a third oil pump.
