STAGE 1: SIMPLE BOLT-ON PERFORMANCE UPGRADE
Ideal for riders that want to enhance the performance, look and sound of their motorcycle: This delivers the perfect foundation for future upgrades.
Stage 1 offers up the most cost-effective step to improve performance. Match any high-flow air cleaner and exhaust, along with the proper ECM calibration to increase the air flow into and out of the engine and you’ll feel up to a 10% increase in performance throughout the entire RPM range.
1 - Enhanced exhaust systems provide less restriction for the gases to escape, but also have the added perk of giving the bike that raw, powerful, Harley sound!
2 - Stage 1 upgrades are a widely recognised addition and will certainly add value to your bike.
3 - Not only will the conversion increase the overall BHP and provide that traditional Harley-Davidson sound, but you'll also find the response from the throttle will be crisper and sharper, and your riding experience more enjoyable overall.
STAGE 2: TAILOR IT TO YOU
Choose a TORQUE CAM or POWER CAM based on your riding style.
OPTION 1: TORQUE KIT
Ideal for riders look for instant passing power at cruising and highway speeds. Upgrade with the torque kit and you’ll feel up to a 15% increase in performance in the low-to-mid RPM range. This option is perfect if you want to experience a crisp throttle response and acceleration that can be felt at slower speeds, great for passing slow moving vehicles without downshifting.
OPTION 2: POWER KIT
Ideal for riders who want to feel the power build and pull all the way to the redline. Feel up to a 25% increase in performance in the mid-to-upper RPM range, along with an adrenaline-pumping burst of speed.
STAGE 3: INSTANT POWER
Accomplished with larger cylinders, matching pistons, and the proper cam upgrade (see Stage 2) - an increase in engine displacement allows the engine to swallow more air and fuel, a higher compression piston squeezes the air and fuel into a more volatile mixture and when combined, generates more power when ignited.
A Stage 3 Upgrade is ideal for riders who want the largest engine displacement and increased power throughout the entire RPM range, with up to a 35% increase in the mid-to-upper RPM range. The upgrade produces instant passing power without downshifting and will deliver excellent stoplight to freeway speed and on-ramp acceleration.
STAGE 4: THE ABSOLUTE BEST PERFORMANCE
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. As well as combining ported cylinder heads and larger throttle body in combination with cylinders, matching pistons and proper cam.
A Stage 4 Upgrade is ideal for riders who want the absolute best performance upgrade available. Expect to feel exceptional acceleration, delivering significant gains and up to a 50% increase in the higher RPM range.
