Maintaining the air filter on your 2015 Suzuki RM85 is essential for engine performance and longevity. A clogged or dirty air filter can dramatically reduce power and lead to premature engine wear, especially for competitive riders. This MotoSport.com guide walks you through the proper cleaning and replacement processall specific to the RM85's unique design. Regular care will ensure optimal throttle response and longevity for your two-stroke engine.
What Makes the 2015 Suzuki RM85 Air Filter Unique?
The RM85 features a dual-stage foam air filter sized specifically for its high-revving 85cc engine. The airbox is positioned directly beneath the seat with easy access, allowing for straightforward maintenance. Riders in sandy or muddy conditions may also consider protective filter screens for added defense against debris build-up and premature clogging. Always handle your filter carefully–wringing or twisting can easily damage delicate foam on this model.
When Should You Clean or Replace the Air Filter?
- Clean every ride in dusty, sandy, or wet conditions.
- Replace the filter if it shows tears, permanent staining, or a loss of foam elasticity.
- Inspect after every few rides as a baseline in clean conditions.
Tools & Supplies You'll Need
- Socket wrench or screwdriver (to remove seat and air cleaner cap)
- Non-flammable filter cleaning solvent
- Foam filter oil
- Pair of gloves
- Plastic bag (for oiling)
- Grease for sealing filter rim
- Replacement air filter if needed
Step-by-Step: Cleaning the 2015 Suzuki RM85 Air Filter
- Remove the Seat
Use a socket wrench or screwdriver to remove the seat—typically two bolts at the rear. Set it aside. - Remove the Air Cleaner Cap
Take off the air cleaner cap to access the filter. Undo the mounting bolt and carefully slide the filter assembly out. - Inspect the Filter
Look for tears, excessive dirt, or breakage. Replace if the foam has deteriorated. - Pre-Clean the Airbox
Wipe the airbox and rim with damp paper towels. Prevent any dirt from falling into the intake tract. - Clean the Air Filter
Immerse the foam filter in a pan filled with a non-flammable cleaning solvent. Gently squeeze (never wring or twist) the filter until all dirt is removed. Repeat with clean solvent as needed. - Dry and Oil the Filter
After cleaning, allow the filter to air dry completely. Pour foam filter oil into a clean plastic bag, add the dry filter, and work the oil through until evenly coated–the filter should be tacky throughout. Squeeze out excess oil without twisting. - Seal the Rim
Lightly apply grease around the seal edge of the filter. This creates a barrier so no dust bypasses the filter in dusty conditions. - Reinstall the Air Filter and Seat
Slide the treated filter back onto its cage, ensuring a tight fit and that no edges fold over. Replace the mounting bolt, reattach the air cleaner cap, and reinstall the seat securely.
Replacement: When & How
If you spot rips or degradation after cleaning, or if the filter no longer fits snugly, replace it with a fresh RM85-specific foam filter from MotoSport.com for the best protection and precise fit.
MotoSport Pro Tips for RM85 Owners
- The RM85's airbox design makes it especially vulnerable to fine dust ingress–always use high-quality oil and replace filters often in off-road race environments.
- Consider a two-stage pre-filter or aftermarket protective air filter screen for extra engine protection where riding regularly in sand or deep mud.
- Never operate the engine without a properly oiled and installed filter, as unfiltered air will cause cylinder and piston scoring almost instantly.
Following these MotoSport air filter maintenance steps will keep your 2015 Suzuki RM85 running at peak performance for seasons to come. Prioritize clean air for max power and engine health.
