These cams unleash an extra 10% horsepower and 3% more torque than a stock PowerPlus engine, and they will not void the bike’s warranty. The Stage 2 Cams increase the engine’s performance when used in conjunction with the PowerPlus Stage 1 Air Intake and the Stage 1 Oval Slip-On Muffler Kit or Stage 1 Slip-On Muffler Kit (each required and sold separately). The cams deliver enhanced, more-aggressive throttle response and significantly greater power across the powerband in every ride mode. Dealer installation is required as the cams come with the required Calibration Code that upgrades the Engine Control Module (ECM) software to Stage 2. No additional software purchase is necessary.
