Nobody has ever, ever said that Aprilia’s thunderous Tuono V4 needed more power. And yet Aprilia has opted to punch out the 999cc V-4 to 1,077cc via a bore increase of 3mm, from 78mm to 81mm. That alone is said to add 8 hp and 6 pound-feet of torque to the new bike’s peak output. Further down the rev range, however, Aprilia says the new 1100 makes as much as 20 horsepower more than the 2014 machine. Dizzam!
