The foam air filter is designed to ensure optimal performance and maximum protection for your engine, particularly for the Beta RR. With over 40 years of experience, the innovative dual-layer design offers a perfect balance between airflow and filtration. The fused layers of open-cell foam, along with a fine inner foam, capture even the smallest particles, protecting the engine from dust and debris.
The new round design not only improves airflow but also minimizes seams thanks to a cutting-edge micro-bonding process. This means there are fewer seams, more foam, and consequently, superior airflow. The fluid and recoil-resistant foam inside the filter ensures long-lasting durability, making it washable and reusable up to 40-50 times.
Made with a two-layer foam, custom-designed with uniformly sized and distributed cells, this filter is hand-assembled and inspected to ensure a perfect fit. Choosing this filter means investing in the protection and performance of your Beta RR for an uncompromised riding experience.
