On paper these two V-Twins match up nicely and in our performance testing seesawed back-and-forth. Dyno charts may not tell lies, but they don’t necessarily tell the entire story, either. A quick glance would leave you to believe that the Aprilia ran circles around the KTM due to its significant 10-pony advantage up top. The Katoom had no plans to roll over that easily, however. Bottom line: The Super Duke makes more power and more torque everywhere in the rev range all the way up to 8000 rpm. This is where the Aprilia goes ballistic, but by that point in the quarter-mile it was already playing catch-up to the orange bike that had smoked it out of the hole. At the stripe, the Tuono takes victory with a 10.68-second, 128.99-mph pass to the Duke’s 10.79/123.92 run. In the real world, however, how much time do you really spend at 9000 rpm? Another notable figure is the 0-to-60 time in which the SD just edged out the Tuono with a 2.9-second time compared to a 3.1.
