Air filter Beta RR 2T 13-19 Beta RR 4T 15-19 Twin Air

Its double-layer foam design filters even the smallest dirt particles, while allowing greater airflow than filters with two separate layers (tested on a flow bench).

The Twin Air filters are slightly smaller than the standard ones, which makes them easier to replace and increases the vacuum space around the filter for better performance.
The flat foam sealing ring sits securely against the air filter box, even in the worst riding conditions.
