Hundreds of test bench runs and complex calculations showed that this exhaust system contributes significantly to a tractable torque curve and compliance with pollution regulations. The middle damper distributes mass and allows for a solid soundscape to be created with a small muffler. It’s a piece of art made of stainless steel. A new balancer shaft has been fitted to meet the higher RPM and spinning mass. The KTM 2020 890 Duke R Naked Bike features a revised cylinder head that accommodates a pair of larger 37mm intake and 30mm exhaust valves, as well as a more excellent lift and a more aggressive camshaft profile. InjectorsĭELL’ORTO developed new sensors in each throttle body specifically for KTM to monitor manifold pressure and adjust the mixture per cylinder accordingly, improving throttle response and smoothing the throttle action more precise throttle inputs. A heavier crankshaft and flywheel may also help improve torque. The KTM 890 Duke R’s horizontally split, high-pressure cast aluminum crankcases allow for reduced wall thickness and weight. Because of its bigger diameter and stroke, more robust compression, and higher maximum RPM limit, the KTM 890 Duke R generates 121 HP and 99 Nm.
