The OG Turbo System is built for riders who want real turbo performance out of their Harley-Davidson, without giving it away at first glance. Clean, stealthy, and brutally effective, this bolt-on system delivers the kind of torque and top-end power that leaves everything else in your mirrors.
Originally designed with the everyday rider in mind, the OG kit brings a smooth, reliable boost without sacrificing rideability. Whether you’re stacking highway miles or twisting through canyon sweepers, this system keeps the throttle responsive and the power on tap.
