Universal Waterproof Air Filter for 125cc-250cc Dirt Bikes, Pit Bikes, and ATVs

Maintain engine reliability in rough terrain with this splash proof air filter engineered for motorcycles, pit bikes, and ATVs. The waterproof construction resists moisture penetration, protecting the cylinder walls and carburetors from water ingestion during stream crossings or rainy trail sessions.

Filtration effectiveness depends on matching the intake tube diameter. This universal unit supports three distinct connection sizes for versatile fitting across different chassis. Buyers must inspect their current filter measurements to select the correct variant:

35MM Diameter: Compact fitment for smaller displacement engines
38MM Diameter: Common standard for mid-range dirt bikes
43MM Diameter: Larger capacity sizing for heavier duty off-road vehicles

This component serves vehicles operating between 125cc and 250cc displacement thresholds. By preventing abrasive dirt particles from bypassing the intake, it reduces wear on piston rings and valves over time. The lightweight assembly weighs approximately 0.15, ensuring negligible impact on overall machine dynamics.

Manufactured in Mainland China, this unbranded accessory replaces worn-out originals regardless of previous manufacturer labels. Regular inspection and cleaning are necessary to sustain airflow velocity and combustion quality under heavy usage loads.
