S&S Cycle 132 in. Big Bore Cylinder Kits

The S&S Cycle 132 in. big bore cylinder kits for a Harley-Davidson® motorcycle provides a significant increase in engine displacement, resulting in a substantial boost in horsepower and torque. This in turn makes the bike significantly faster with more power across the powerband, particularly noticeable in low and mid-range acceleration, while still maintaining compatibility with stock crankcases and retaining the stock engine height, offering a "sleeper" advantage with minimal visual modification. These big bore cylinder kits are typically designed to work with existing engine components like the stock head gaskets and flywheels. This makes installing them a significant investment compared to other performance upgrades. Each kit is tailored with the necessary components for your specific model. Many kits feature a powdercoat finish that closely matches the factory look. To fully optimize increased power, proper tuning with adjustments to fuel injection and ignition timing may be necessary. Order the 132 in. big bore cylinder kit designed specifically for your HD® model and engine to ensure proper fitment.
