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.
