Check out our Milwaukee-Eight 117 Performance upgrades to this slick looking 2018 FLTRXSE CVO, here at Top Dead Center Performance.  Harley Davidsons new engine is great BUT removing OEM factory components, like plastic tappet cuffs and going with trusted performance products like Feuling Parts; S&S Cycle; Khrome Werks and TechnoResearch will always be in your favor. And, the Dyno results don’t lie, factory base run 93HP & 112TQ not bad.  The Stage II here we have a solid engine now with a final run of 114HP and 125TQ, this M8 117 is ready for any ride.
