S&S Cycle's 96 in. big bore cylinder kits for a Harley-Davidson® motorcycle provides significant benefits by increasing the engine displacement, leading to noticeable power gains, particularly in the low and mid-range torque, resulting in better acceleration and improved overall performance, especially for riders looking for a more powerful ride without drastically altering the engine character. The larger cylinder bore displaces more air, allowing for more fuel to be burned, generating more power throughout the powerband, especially noticeable during acceleration. Big bore kits tend to focus on increasing low and mid-range torque, which is beneficial for everyday riding and pulling heavy loads. With a larger cylinder volume, the engine can react quicker to throttle inputs, leading to a more responsive feel. Compared to other performance modifications, a big bore kit can be a relatively straightforward upgrade, often requiring minimal additional changes to the engine. One of these S&S Cycle 96 in. big bore kits can be a great starting point for further performance upgrades like camshaft changes, ported heads, and upgraded intake systems to maximize power gains.

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.
