Product Details

This is the S&S Cycle 58mm Single Bore Throttle Body Kit, designed for 2001-2005 Big Twin Harley-Davidson motorcycles. If you're looking to improve your engine's breathing and unlock more performance potential, a larger throttle body like this is a key component. It allows more air into the engine, which is essential for making more power, especially when paired with other engine modifications.

S&S Cycle is well-known for building robust engine components, and this throttle body is no exception. The 58mm bore size is a significant step up from stock, providing a much greater volume of air to the cylinders. This upgrade is particularly beneficial for riders who have already modified their engines or are planning to do so. It's built to handle the demands of a performance-oriented engine, ensuring consistent airflow and responsiveness. This kit is designed to fit a wide range of Harley-Davidson Big Twin models from 2001 to 2005, including popular bikes like the Road King, Fat Boy, and Dyna Super Glide.

When undertaking an upgrade like this, it's important to consider that other supporting modifications might be necessary to take full advantage of the increased airflow. This includes tuning your engine's fuel delivery to match the new air volume. Always refer to the manufacturer's installation instructions for specific details and recommendations regarding supporting components and tuning.
