S&S Cycle 1200cc to 1250cc Hooligan Cylinder Kits
Whether you are looking for better acceleration for everyday riding or more power for spirited driving, S&S Cycle 1200cc to 1250cc Hooligan cylinder kits provide a noticeable improvement. The larger displacement from 1200cc to 1250cc directly translates to more power, making the bike faster and more responsive, especially noticeable in acceleration and mid-range torque. These kits are designed to be "bolt-on" meaning they can be installed without needing to machine the engine cases or rebalance the crankshaft, making the upgrade process fairly straightforward. Each kit is tailored with the necessary components for your specific HD® model. Most Hooligan kits utilize the existing stock heads, pushrods, and fuel system, minimizing the need for additional parts or adjustments. Compared to a full engine rebuild or custom build, S&S Cycle's Hooligan kits are a relatively affordable way to significantly improve performance. Select the kit designed for your application needs.

S&S Cycle 883 to 1200cc Hooligan Cylinder Kits
An 883 to 1200cc Hooligan cylinder kit for a Harley-Davidson®, like the ones made by S&S Cycle, provides a significant increase in engine displacement, resulting in substantially more power and torque without requiring major engine modifications, making it a popular upgrade for riders seeking better performance on their Sportster 883, with benefits like increased horsepower—by boosting the engine size from 883cc to 1200cc, the Hooligan kit delivers a noticeable power gain, allowing for better acceleration and highway cruising capabilities. Typically these kits are designed as "bolt-on" upgrades, meaning they can be installed without needing extensive machining or engine rebalancing, making the process relatively simple and straightforward. Compared to a complete engine rebuild, a Hooligan kit is a cost-effective way to significantly improve your bike's power. When installing a Hooligan kit, it may be necessary to upgrade the clutch to handle the increased torque produced by the larger engine. Depending on the specific kit and your bike setup, you may need to adjust fuel injection mapping to optimize performance.
