Description
If you’re running an 883cc or 1200cc Big Twin and want genuine displacement gains without a complete engine overhaul, the S&S Cycle Piston Kit 92-1411 delivers a straightforward path to 1250cc. This cast flat-top design is engineered for reliability across a wide range of HD Big Twin applications, and the 10.3:1 compression ratio strikes a practical balance between street performance and engine longevity. Pair it with S&S CNC ported heads for optimal results, or run it with stock heads if your build calls for a simpler approach.
