Product Details

S&S Cycle has been a well-known name in performance V-twin engine components for decades, building a reputation for well-built parts that help riders get the most out of their motorcycles. This 58mm Single Bore Throttle Body is a prime example of their commitment to performance for 2006 and newer Big Twin Harley-Davidson models.

This throttle body features a 58mm bore diameter, which is larger than stock, allowing for increased airflow into your engine. More airflow means your engine can potentially make more power, especially when paired with other performance modifications. The single bore design is a straightforward approach that focuses on efficient air delivery. It's designed to fit your 2006 or later Big Twin motorcycle, making it a direct replacement for the stock unit, though you'll want to ensure all supporting modifications are compatible.

When considering this upgrade, remember that it is not CARB approved and therefore cannot be shipped to California. This part is intended for off-road use or in states that do not have emissions testing requirements that would be affected by this component. Always consult your local regulations and manufacturer's recommendations for installation and use.
