This Stage III kit has been developed to deliver the kind of real-world power increase Touring riders will feel each time they roll on the throttle. The bump up in displacement and compression paired with a Screamin’ Eagle® SE8-511 camshaft deliver a significant increase in torque and power over stock and may restore the sensation of riding solo when you’re loaded down with a passenger and gear.
