Milwaukee-Eight® Stage III Upgrade
THE BASICS
STAGE III
THE PERFORMANCE
• 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 • Displacement increases are accomplished with larger cylinders, matching pistons, and the proper cam upgrade
• Riders will experience a performance increase throughout the entire RPM range, with up to a 35% increase in the mid- to upper- RPM range • Produces instant passing power without downshifting • Delivers excellent stoplight to freeway speed and on-ramp acceleration
When installed by an authorized Harley-Davidson® Dealer at the time of vehicle delivery, compliant kits do not impact the vehicle’s limited warranty.
