Description

Experience a dramatic transformation in your motorcycle's performance with the S&S Cycle 124" Power Package Big Bore Kit. This meticulously engineered engine upgrade is designed to provide a substantial increase in power, featuring a robust 124" displacement and an impressive 11.1:1 compression ratio. The kit includes high-quality forged pistons, ensuring durability and reliability under extreme conditions. With a bore size of 4.250" and a stroke length of 4.375", this Power Package is engineered for optimal combustion and power delivery. The updated fins on the cylinders not only enhance the aesthetic with a striking black granite and highlighted finish but also aid in efficient oil cooling, maintaining optimal engine temperatures. Proudly made in the USA, this kit is a testament to S&S Cycle's commitment to superior craftsmanship and performance.

The comprehensive nature of this S&S Cycle 124" Big Bore Kit extends to its advanced internal components. It features a precision-machined billet aluminum oil pump and cam plate, engineered with independent scavenge sections for both the flywheel cavity and camchest, ensuring superior oil circulation. Debris screens in both scavenge pickups and a strategically placed magnet in the camchest prevent contaminants from entering the oil pump, extending engine life. This system boasts a remarkable 44% flow increase on the supply side and a 58% flow increase on the scavenge side, with an adjustable pressure relief valve for fine-tuning. Quickee pushrods, hand-assembled tappets with close tolerances for reduced valve train noise, and hard-anodized billet aluminum tappet cuffs that ensure stability in high-lift, high-RPM situations complete this high-performance package. The S&S 550 camshaft, specifically designed for big bore applications, works in harmony with high-performance conical single wire valve springs capable of handling up to 0.605" lift, delivering a truly exhilarating riding experience.
