The Twin Air Air Filter, manufacturer part number 158089 and vendor part number 715-8089, is designed for select 2020-2022 Beta RR two-stroke motorcycles. This replacement foam air filter helps protect the engine from airborne dirt, grime, and sand while supporting consistent airflow for off-road performance. Its thick, flat foam sealing ring creates maximum contact with the airbox and functions as a breathable gasket for improved air passage.
The filter uses a dual-layer, open-pore foam construction. The coarse outer foam captures larger contaminants, while the fine inner foam helps trap smaller particles without unnecessarily restricting airflow. Twin Air’s exclusively formulated adhesive is built to withstand repeated cleaning, including cleaning with harsh solvents or gasoline, helping support long-term serviceability. The filter is slightly smaller than the original equipment filter to provide additional air space and improve circulation around the filter.
Designed for a direct fit in the specified airbox, this Twin Air filter is compatible with 2020, 2021, and 2022 Beta 125 RR, Beta 200 RR, Beta 250 RR, and Beta 300 RR two-stroke models. Confirm the motorcycle model and year before installation. The Twin Air brand and part number 158089 provide reliable reference points when replacing or servicing the motorcycle’s air filtration system.
