With new motorcycles, it’s only a matter of time until an aftermarket company or publication straps one into a dyno rig. In this case, Visordown took a KTM 790 Duke down to Big CC Racing for a few power runs.
Called the Scalpel, KTM’s sharpest tool in the shed is powered by the company’s first parallel-twin engine. With a LC8c unit at its disposal, the machine has a manufacturer claimed 103 hp at 9,000 rpm and 63.6 pound-feet of torque at 8,000 rpm. In the dyno run, its numbers are a bit off as Visordown managed to squeeze out 99.65bhp at 9,400rpm and 60.72 ft lb of torque. Still very impressive numbers for a 799cc parallel twin.
They’ve even taken it upon themselves to dyno test the 790 Duke in its various ride modes; rain, street, track, and sport. Unlike the relatively linear power delivery in normal mode, the various optional ride modes give you a softer power delivery by gradually opening up the throttle. Granted, you can still get 100% throttle opening if you twist the grip fully, but they’ve found that the “ECU opens the injector body valves at a slower rate.”
These charts are worth a look if you’re planning to tune the KTM 790 Duke.
