RFX Foam Air Filter FXAF8000255NO - Beta 125-480 RR 2020-2024

Product Description

The RFX Air Filter delivers dependable intake filtration and consistent airflow across Beta RR two-stroke and four-stroke motorcycles. Manufactured by Multi Air, this twin-layer foam air filter allows your engine to breathe cleanly while providing vital barrier protection against airborne roost, sand, and fine trail dust.

Featuring a breathable twin-layered foam design, the coarse outer layer catches larger dirt and debris, while the dense inner layer traps micro-particles before they can reach the intake tract. Built using flame-retardant nonflammable foam suited for four-stroke applications, it provides an exact airbox fitment backed by Multi Air's 30-plus years of off-road competition experience.

Frequently Asked Questions

Q: Does this RFX air filter come pre-oiled or dry?
A: This filter (MPN FXAF8000255NO) is supplied dry (un-oiled) and must be properly treated with foam air filter oil prior to installation.

Q: Can this filter be used on both 2-stroke and 4-stroke Beta RR models?
A: Yes, it is built to the exact airbox dimensions shared across the listed 2-stroke and 4-stroke Beta RR platforms.

Q: Why is nonflammable foam used on 4-stroke models?
A: Four-stroke powerplants can backfire through the intake tract. Nonflammable foam helps prevent backfire sparks from igniting the filter media or oil.

Expert Pro-Tip: When oiling a dry foam air filter, work foam filter oil thoroughly through both foam layers until the color is completely uniform across the entire surface. Gently squeeze out any excess oil without twisting or wringing the seams, and allow the carrier solvent to evaporate for 15 minutes before seating the filter cage into the Beta airbox.
