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.

S&S Cycle's 88 in. big bore kits provide significant benefits by increasing the engine displacement, resulting in more power and torque, especially noticeable in the low to mid-range powerband, while generally maintaining the stock engine character and rideability; essentially giving the bike a stronger punch with increased acceleration without drastically altering its feel. The larger bore size allows for more air and fuel to be ingested per combustion cycle, leading to a noticeable boost in power output, particularly in the low and mid-range rpm bands. For riders who frequently haul loads, the increased torque can be beneficial for pulling heavier trailers or carrying extra cargo. Many 88 in. big bore kits are designed to work with mostly stock components, requiring minimal additional engine modifications for installation. Compared to other performance upgrades like high-lift cams or forced induction, a big bore kit is often considered a cost-effective way to significantly increase engine power. After installing a big bore kit, proper engine tuning with adjustments to the fuel injection or carburetor settings is crucial to optimize performance and ensure efficient combustion. Select the S&S Cycle big bore kit specifically designed for your HD® model and year.

S&S Cycle's 93 in. big bore cylinder kits can provide significant benefits by increasing engine displacement, resulting in noticeable gains in horsepower and torque, particularly in the low to mid-range powerband, making for a more powerful and responsive ride with improved acceleration, while often being considered a relatively easy bolt-on upgrade that doesn't require major engine modifications. The larger cylinder bore allows for more air and fuel to be ingested during each combustion cycle, leading to a substantial increase in horsepower and torque. With more power available, the motorcycle will accelerate quicker and more readily, especially in everyday riding situations. While there may be a slight decrease in fuel efficiency due to the increased displacement, it is often negligible compared to the performance gains. To maximize the benefits of a big bore kit, it is often recommended to upgrade other engine components like the camshaft and intake system to optimize airflow and further enhance performance. Depending on the specific big bore cylinder kit and your bike's engine configuration, proper tuning with a power commander or similar device may be necessary to ensure the engine runs efficiently with the increased displacement.
