The S&S Cycle Big Bore Kit increases the displacement of Milwaukee-Eight engines, available for both 107" and 114" models. The kit expands the engine to 124" or 128" without requiring machining or splitting the cases, making installation straightforward for skilled technicians. Constructed with premium aluminum cylinders that feature cast-in iron liners, the kit includes cylinders, forged pistons, rings, and necessary gaskets (head, base, and exhaust). The design allows for optimal performance even with stock cylinder heads. It features a 4.250" bore and an 11:1 compression ratio. This bolt-on upgrade is available in different finishes and with optional fin highlighting. It provides a significant increase in power and is ideal for riders looking to enhance their engine's performance.
