Shop parts for a 2012 Yamaha TTR110 Dirt Bike.

Keeping your 2012 Yamaha TTR110 running its best means regular air filter maintenance. Dusty trails – especially common with this model’s typical use – demand frequent cleaning and replacement. A clean air filter keeps the engine breathing easily, protects against harmful debris, and prolongs engine life.

Proprietary MotoSport Air Filter Service Steps for the TTR110

  • Remove the right side fairing by loosening and removing three Phillips head bolts to expose the airbox.
  • Extract the air filter element gently, watching for debris that may fall into the airbox. Inspect for dirt, tears, or deterioration. The stock filter is a reusable foam type, but any damage – such as tears or breakdown – means it’s time for replacement.
  • Clean the filter using a mild soap and warm water or a cleaning product designed for foam air filters. Rinse thoroughly and let it dry completely. For heavy dust, service more frequently than the manual’s interval.
  • Oil the foam filter with a high quality air filter oil. Even new replacement foam filters require oiling for proper dust filtration.
  • Clean the airbox cavity and check the drain plug at the lower rear side. This is crucial on the TTR110, which can accumulate water or oil in the airbox when riding in wet conditions.
  • Inspect for wear closely. Foam elements can last many cleanings, but cracks and rips mean immediate replacement.
  • Reinstall the filter securely, ensuring full perimeter seal in the airbox. Replace the fairing and tighten bolts – do not overtighten, as the plastic can strip or crack.

TTR110-Specific Notes

  • The 2012 TTR110’s foam filter is reusable. Owners should expect to clean rather than replace unless damage is present, which is common after extended dusty or muddy rides.
  • Always service sooner if you’ve ridden in wet, muddy, or especially dusty terrain – a well-maintained filter means optimal performance and longer engine life.
  • If replacing with an aftermarket foam filter, ensure it’s compatible with the TTR110’s airbox design for a proper seal. Inspect the drain tube during each service.
  • Dispose of cleaning and oiling chemicals in a safe, environmentally responsible manner. Clean and store your tools after each service.

Typical Questions from TTR110 Riders

  • Can I use dish soap? Yes, but a dedicated air filter cleaner and oil are preferred for engine protection.
  • How often should I service the filter? Follow your owner’s manual schedule, but increase frequency if you ride in dusty or wet conditions.
  • Is the filter the same as other Yamaha models? Only use part numbers specific to your 2012 TTR110.

Proper air filter maintenance protects your investment in your 2012 Yamaha TTR110. Whether you’re cleaning or replacing, rely on MotoSport for all parts and accessories – and always ride prepared after each service.
