RACETECH Air Box Cover (left) for HUSQVARNA FC, FE, TC, TE 125, 250, 300, 350, 450 and HUSABERG FE 450, 501 2025-2026

The RACETECH gauche air box cover is designed for HUSQVARNA FC 250, FC 350, FC 450, FE 250, FE 350, TC 125, TC 250, TC 300, TE 125, TE 250, TE 300 and HUSABERG FE 450, FE 501 from 2025 to 2026. The air box cover closes off the side of the air box under the seat: it protects the filter from spray and finishes off the look of the bike. It sits right against the rider's leg, which is why it gets scratched and cracked over time.

Choosing the colour

All colours have the same shape: pick the one that matches your side panels or your graphics.

When to replace it?

• Cover cracked, broken or scratched by boots.
• Mounting points torn out: it rattles or lets dust in.
• Faded colour, or different from the rest of the plastics.

Check the bike's model year and the side (left or right) when it is given. A vented cover lets more air into the air box, but also more dust.

Fitting tips

1. Remove the seat if necessary, then the old cover, keeping the hardware.
2. While you are there, check the condition and the oiling of the air filter.
3. Refit the new cover, checking that it sits flush against the air box.

Why RACETECH?

The brand has supplied the plastics for Mitch Payton's Pro Circuit Kawasaki team, one of the most successful teams in AMA Supercross, as well as for the Beta Offroad Factory team. Its Worx chain guide is a one-piece design fitted with a removable, self-lubricating TPU internal wear pad.

Frequently asked questions

What is a vented cover for?
It improves airflow, which helps on dry, fast terrain. In mud or rain, a solid cover protects the filter better.
