The New 107 and 114 Milwaukee-Eight™ Engines
For 2017, Harley-Davidson® is launching the ninth generation of its venerable Big Twin, called the Milwaukee-Eight™.
It is named in honor of its birthplace and its number of valves-twice as many as found on the Twin Cam motor that's been in the lineup since 1999. Harley-Davidson® says the new engine platform provides faster throttle response, more torque, better sound, improved fuel economy and a smoother ride. The new engines, which retain their classic 45-degree V-twin architecture, will power all 2017 Touring and Trike models in two displacements and three variations.
