S&S Cycle has built American V-twin performance parts in Viola, Wisconsin since 1958 — flywheels, carburetors, cams, cylinder heads and complete crate engines. When a Harley owner talks about a 124, a 128 or a 131 build, they are usually talking about S&S. Few names carry more weight with engine builders in this space.
Unleash massive power on your Harley Touring model with the S&S Cycle T124 long-block engine. This high-compression, 124 cubic inch powerplant is designed as a direct bolt-in upgrade, transforming your ride's performance. It's engineered for compatibility with stock-length manifolds and throttle bodies, simplifying the installation process.
When a stock engine just won't cut it anymore, the S&S Cycle T124 long-block engine delivers the raw power and reliability you demand for your Harley Touring bike. Displacing a formidable 124 cubic inches, this engine is built for riders who crave more than just a mild upgrade. Its high-compression design ensures instant throttle response and exhilarating acceleration, making every ride an adventure.
The S&S Cycle T124 long-block is a serious upgrade for any Touring rider. While it's designed for straightforward installation, remember that fuel and ignition systems must be sourced separately to complete your build. This engine is built to integrate smoothly with your existing larger EFI tuner and fuel system components, allowing for a cohesive and powerful setup. Always confirm compatibility with your specific Harley Touring model, noting it does not fit Twin-Cooled variants.
What Harley-Davidson models does this engine fit?
This S&S Cycle T124 long-block engine is designed for 2007-2016 Harley-Davidson Touring models. It is not compatible with Twin-Cooled Touring variants. Please confirm fitment for your specific model.
What additional components will I need to purchase?
While the long-block is a comprehensive upgrade, you will need to source fuel and ignition systems separately. An oil line kit must also be purchased separately to complete the installation.
Is this engine compatible with my stock throttle body and manifold?
Yes, the machined cylinder heads are designed to fit stock-length manifolds and throttle bodies without modification, simplifying the installation process.
