Maintaining the air filter in your 2013 GAS GAS TXT-PRO-125 is essential for top-tier performance, maximum engine protection, and long-lasting reliability. The fine-tuned 125cc 2-stroke engine is highly responsive to airflow, making proper air filtration absolutely critical for efficient combustion and throttle response—especially in trials riding where precision rules.
Air Filter Overview: 2013 GAS GAS TXT-PRO-125
- The air filter is located within the airbox beneath the seat and behind the side panels.
- This model uses a reusable foam air filter element.
- Given the physical dimensions of the TXT-PRO-125 (length: 2045 mm, width: 825 mm, height: 1130 mm), access to the filter is straightforward for routine cleaning and replacement.
Cleaning the Air Filter
Frequency: Clean after every 2-5 rides, or more frequently in dusty or wet conditions.
- Remove the seat and side panel to access the airbox.
- Cautiously pull out the foam filter. Take care not to let debris fall into the intake boot.
- Inspect the filter for tears or degradation. Replace if damaged.
- Wash the filter with mild soap and warm water, gently squeezing — not twisting or wringing — to avoid damage.
- Rinse thoroughly until water runs clear. Allow to air dry completely.
- Once dry, apply air filter oil evenly, working it through the foam for comprehensive coverage. Do not over oil—excess will restrict airflow.
- Wipe the filter sealing surface and the airbox rim. A thin layer of grease on the sealing edge can improve dust protection.
- Reinstall the filter, ensuring perfect seating to prevent air bypass. Reattach panels and seat properly.
Air Filter Replacement
- Replace with a new OEM-quality foam filter if the current one shows any tears, hardening, shrinking, or residual debris that will not wash out.
- Always pre-oil the new filter prior to installation.
Special Notes for GAS GAS TXT-PRO-125 Owners

- Replacement air filters and maintenance products must be compatible with GAS GAS TXT Pro 125 years 2002–2013 for optimal fitment and performance.
Recommended Maintenance Tips
