This kit was developed for the rider looking for a solid “seat of the pants” increase you can feel – every time you roll on the throttle. The increase in displacement and the bump in compression deliver a significant increase in torque and power over stock while restoring the sensation of riding solo when taking that long trip with a passenger and luggage. For ’17 and ’18 Touring models, installation of oil pump cover P/N 62400206 is recommended (sold separately). All models require ECM calibration with Screamin’ Eagle® Pro Street Tuner for proper installation. See Dealer for details.
