If an item is designated as "Competition and Racing Vehicles Only", we will require a race waiver be digitally signed before an item can ship to California.

The S&S Cycle Big Bore Kit is a bolt-on upgrade for Milwaukee-Eight engines, designed to increase displacement from 107" to 124" or from 114" to 128". It features premium aluminum cylinders with cast-in iron liners and forged pistons with an 11:1 compression ratio. The kit includes cylinders, pistons, rings, and necessary gaskets (head, base, and exhaust) for installation. It provides the largest bore possible without requiring machining of the crankcase. Available in different finishes, this kit is ideal for riders seeking improved performance while retaining stock cylinder heads. Installation should be performed by a skilled technician to ensure proper assembly and clearance.
