S&S Cycle 84-99 BT V124 Long Block Engine w/ 640 Cams & Chrome Billet Gear Cover

Built with a 4.25-inch bore and a 4.5-inch stroke, this S&S Cycle V124 long block engine is designed to give your 1984-1999 Big Twin motorcycle a significant power boost. It comes pre-assembled with S&S 640 cams and a chrome billet gear cover, meaning much of the complex internal work is already done for you. This engine is a substantial upgrade for riders looking for more torque and horsepower from their V-twin.

The V124 features a 124 cubic inch displacement, achieved through its generous bore and stroke dimensions. This larger displacement allows for more air and fuel to be processed, directly translating to improved performance. The included S&S 640 cams are chosen to complement the engine's displacement, providing a strong powerband that's well-suited for cruising and spirited riding. The chrome billet gear cover not only adds a custom look but is also a well-made component that seals the engine's timing components.

This engine is sold without induction or ignition components, giving you the flexibility to choose the exact carburetor or fuel injection system and ignition module that best suits your riding style and existing setup. It's important to note that this engine is not CARB approved and cannot be shipped to California. For a complete build, you'll need to source compatible intake and ignition parts, and ensure your local emissions regulations are met.
