Description
If you’re building a 106″ stroker engine for your HD Big Twin, you need pistons engineered specifically for that displacement—not generic aftermarket units. The S&S Cycle 92-1212 forged pistons are purpose-built for the S&S 106″ stroker kit with 4-1/2″ stroke flywheels, ensuring proper compression, reliable ring seating, and the durability required for high-output builds. These forged units deliver the strength and precision necessary to handle the increased cylinder pressure of a stroker engine without compromise.
