Description
Rather than sinking time and money into rebuilding an aging 80″ Evolution engine, the S&S Cycle V80 Series delivers a complete, factory-fresh replacement that bolts directly into your 1984–’99 Harley big twin chassis. You’ll gain measurable power gains without the downtime of a rebuild, while leveraging your existing carburetor, ignition, and air cleaner setup to keep costs down. This is the smart upgrade path for riders ready to move beyond stock performance.
