STAGE I BENEFITS
A stage 1 upgrade would be ideal for riders who want to enhance the performance, look and sound of their motorcycle. This is the most cost effective step to improve performance and is a required step for future performance upgrades.
The stage 1 upgrade matches any Screamin' Eagle® high-flow air cleaner and exhaust with the proper ECM calibration to increase the airflow into and out of the engine.
STAGE I PERFORMANCE
The rider will feel up to a 10%* increase in performance when compared to stock bikes throughout the entire RPM range.
STAGE II BENEFITS
Customers have a choice of a TORQUE CAM or POWER CAM based on their riding style.
A TORQUE KIT is ideal for riders looking for instant passing power at cruising speeds. A POWER KIT is ideal for riders who want to feel the power build and pull all the way to the redline.
A performance cam increases both the lift in the valve train (pushing the valve open farther) and the duration of the valve opening (how long the valve stays open).
STAGE II PERFORMANCE
The rider will feel up to a 15%* increase in performance when compared to stock bikes in the low to mid RPM range. Experience crisp throttle response and acceleration that can be felt at slower speeds, perfect for passing slow-moving vehicles without downshifting.
The rider will feel up to a 25%* increase in performance when compared to stock bikes in the mid to upper RPM range. Experience an adrenaline-pumping burst of speed while heading toward the redline
STAGE III BENEFITS
Ideal for riders who want the largest engine displacement and increased power throughout the entire RPM range. An increase in engine displacement allows the engine to swallow more air and fuel, while a higher-compression piston squeezes the air and fuel into a more volatile mixture, generating more power when ignited.
Displacement increases are accomplished with larger cylinders, matching pistons and the proper cam upgrade.
STAGE III PERFORMANCE
Riders will experience a performance increase throughout the entire RPM range, with up to a 35%* increase when compared to stock bikes in the mid to upper RPM range. The Stage III upgrade produces instant passing power without downshifting and delivers excellent stoplight to freeway speed and on-ramp acceleration.
STAGE IV BENEFITS
Ideal for riders who want the absolute best Harley-Davidson® performance upgrade available. The Stage IV upgrade provides the highest-level performance upgrade available to provide a maximum increase in displacement, compression and flow. Higher-flowing CNC ported cylinder heads and larger bore throttle body increase the velocity and feed large volumes of air and fuel into the engine, which maximizes power on a larger displacement engine.
Combines ported cylinder heads and larger throttle body in combination with cylinders, matching pistons and proper cam upgrade.
STAGE IV PERFORMANCE
The rider will feel exceptional acceleration, delivering significant gains and up to a 40%* increase when compared to stock bikes in the upper RPM range.
