Shop parts for a 2016 Suzuki DRZ70 Dirt Bike.
The 2016 Suzuki DRZ70 relies on a foam air filter for optimal engine performance – a crucial component protecting your bike's engine from dirt and debris. Regular cleaning and replacement are essential for sustained performance and engine longevity, especially if you ride dusty trails or use the DRZ70 for youth learning and off-road fun. This MotoSport-exclusive guide covers everything you need to properly maintain the air filter on your DRZ70, highlighting tips unique to this model.
Why Regular Air Filter Maintenance Matters
- Protects the engine: The DRZ70's air-cooled engine depends on a clean foam air filter to prevent dirt and sand from entering and causing wear.
- Improves throttle response & power: A dirty filter can reduce airflow and choke the engine, especially noticeable in small-displacement bikes like the DRZ70.
How to Remove the DRZ70 Air Filter
- Locate the air filter cover on the left side of the bike.
- Remove the four Phillips screws securing the cover. Set these aside safely (They are small — don't lose them.).
- Gently pull the cover away and carefully take out the old air filter. Inspect it for excessive dirt or tears. If it looks very grimy, consider a replacement, as new filters are affordable and easy to install for the DRZ70 (Replacement can be as quick as a couple of minutes.).
Cleaning and Oiling the DRZ70 Foam Air Filter
- Cleaning: Wash the foam filter in warm water with a mild detergent or a dedicated air filter cleaner. Gently squeeze – do not wring – to avoid tearing the foam. Rinse thoroughly until all dirt and cleaning solution is gone.
- Dry: Allow the filter to air dry completely before oiling. Never use compressed air or high heat.
- Oiling: Apply quality foam filter oil evenly. Squeeze out excess oil so the filter is well-saturated but not dripping. For the DRZ70, petroleum-based or biodegradable foam filter oils are both options, but always check compatibility with your chosen filter type.
- Wipe out the inside of the air boot and airbox using a clean rag – residual dirt inside can easily get drawn into your engine during reinstallation.
Reinstalling or Replacing the Filter
- Install the cleaned and oiled (or new) foam filter into the cage, making sure it seats evenly all the way around the airbox opening.
- Apply a thin layer of waterproof grease on the base of the filter for an extra tight seal, especially if you ride in extremely dusty or wet conditions.
- Replace the air filter cover and secure it with the four Phillips screws.
When to Replace the DRZ70 Air Filter
- If the filter is torn, excessively stained even after washing, or showing signs of breakdown, replace it. The 2016 DRZ70 uses a dual-stage foam air filter for increased protection, and replacements are readily available. Select filters designed specifically for 2008–2026 DRZ70 models to ensure proper airflow and fit.
DRZ70 Air Filter Quick Facts and Owner Tips
- The DRZ70's filter design offers superior protection thanks to its dual-layer foam construction. Regular maintenance is especially important for youth riders learning good habits and for bikes used in dusty environments.
- Always check for a proper fit and a solid seal to prevent any unfiltered air from sneaking past the filter. Extra vigilance protects the small, high-revving DRZ70 engine for years of reliable fun.
- Plan to service the air filter after every 1–2 rides in harsh conditions, or every 4–5 rides in light trail use.
