What is the main benefit of a 70mm throttle body?

A larger 70mm throttle bore allows for a greater volume of air to enter the engine compared to a stock throttle body. This increased airflow can lead to improved throttle response and potentially more horsepower, especially when other engine modifications are present.

What does 'Not CARB approved' mean for this part?

CARB (California Air Resources Board) approval is required for emissions-related parts sold in California. Since this throttle body is not CARB approved, it cannot be legally shipped to or installed on vehicles registered in California.

What is the finish on this throttle body?

The throttle body features a wrinkle black finish. This is a type of powder coating that offers a textured look and provides a durable surface resistant to heat, scratches, and general wear.

Product Details

This 70mm Throttle Hog throttle body kit from S&S Cycle is built with a substantial 70mm bore, offering a significant airflow increase over stock for your 2002-2005 Big Twin motorcycle. The wrinkle black finish not only looks sharp but also provides a durable surface that resists scuffs and scratches, keeping your engine bay looking clean. When you're looking to get more air into your engine for improved performance, a larger throttle body like this is a key component.

S&S Cycle has a long history of making well-built performance parts, and this throttle body is no exception. The larger diameter allows your engine to breathe more freely, which can translate to better throttle response and more power, especially when paired with other engine modifications. This kit is designed as a direct replacement for the stock throttle body, making installation more straightforward. The wrinkle black powder coat is applied evenly and holds up well to engine heat and typical road grime.

Keep in mind that this throttle body is not CARB approved, so it cannot be legally shipped to California. If you're building a performance engine and want to maximize airflow, this 70mm Throttle Hog is a solid choice for your 02-05 Big Twin.
