2017 saw the launch of Harley-Davidson’s new Milwaukee-Eight engine, so called due to its single-cam-actuated eight valves. Making 88.5bhp @ 5450rpm and 111lb-ft @ 32540rpm, the air/oil-cooled 107 (1745cc) motor currently powers the entire 2017 Touring Range of Harley-Davidsons. A 107 Twin-Cooled (air and water) motor is fitted to all the bikes with fairing lowers, and boots power and torque to 90bhp and 112lb-ft, while keeping the rider and pillion, not to mention the motor, a little cooler.
