RFX Pre-Oiled Air Filter FXAF8000255PO - Beta 125-480 RR 2020-2024

Product Description

The RFX Pre-Oiled Air Filter is manufactured by Multi Air to deliver unrestricted airflow and engine protection across Beta RR two-stroke and four-stroke motorcycles. Designed for competitors and trail riders alike, this factory pre-oiled air filter arrives completely saturated with filtration oil and ready for immediate drop-in installation straight from the box.

Featuring an engineered twin-layer foam construction, the outer open-pore layer traps coarse grit, sand, and roost, while the dense inner layer captures micro-dust particles before they can enter the intake boot. Built using flame-retardant foam to protect against intake backfire on four-stroke applications, it provides a precise airbox fitment developed through Multi Air's 30-plus years of off-road competition experience.

Frequently Asked Questions

Q: Is this RFX air filter ready to install immediately out of the packaging?
A: Yes, this filter comes pre-treated with filter oil from the manufacturer, allowing direct installation into your airbox without manual oiling.

Q: Can this air filter be used in both 2-stroke and 4-stroke Beta RR models?
A: Yes, it is designed to fit the specific airbox shared across the listed 2-stroke and 4-stroke Beta RR platforms.

Q: What makes flame-retardant foam beneficial on 4-stroke engines?
A: Four-stroke engines can produce sudden backfires into the intake tract. Nonflammable foam resists catching fire if exposed to backfire sparks.

Expert Pro-Tip: Because Beta airboxes feature tight clearances around the filter cage locating pins, always check the bottom alignment tab before clamping the cage bail wire shut. Run your fingers around the entire sealing lip after seating it to confirm the foam base has not bunched or folded under the cage edge, ensuring a leak-free seal before you fire the bike.
