Tools & Materials Needed

  • Engine oil (Refer to your manual for recommended type and capacity; typically 10W-40 full synthetic for dirt bikes)
  • New oil filter (Cartridge style for the RMX450Z)
  • Oil drain pan
  • 10mm socket or wrench
  • 8mm socket or wrench
  • Flathead screwdriver or pick tool (for filter removal)
  • Gloves
  • Shop rags
  • Measuring cup (for accurate oil refill)
  • Torque wrench (to match Suzuki’s factory specs)

Model-Specific Call-Outs for the 2017 RMX450Z

  • The RMX450Z shares its engine architecture with the RMZ450, but has additional screens/filters inside the engine, so don’t skip screen cleaning.
  • Change oil every 6 hours of operation for hard riding, or sooner in racing or extreme conditions.
  • Always clean/inspect the oil strainer and screen filters in addition to replacing the primary oil filter.
  • Be gentle with bolts, use proper torque: Oil drain bolt: 15.5 ft-lbs, Oil filter cover: 8-9 ft-lbs as per similar Suzuki RMZ specs.

Step-by-Step Oil Change Process

  1. Warm Up the Engine
    • Start the bike and let it idle for 2-3 minutes until the radiators are just warm. This helps the oil thin out for a complete drain.
  2. Position the Bike and Tools
    • Place the bike upright on a stand. Slide the oil drain pan under the engine.
  3. Remove the Oil Drain Bolt
    • Locate the drain bolt (10mm) directly under the engine. Loosen and remove, allowing oil to drain completely. Remove the oil filler cap while draining to help flow.
    • Be cautious with hot oil and always replace the aluminum crush washer if worn.
  4. Clean the Oil Strainers and Screens
    • On the RMX450Z, inspect and clean both mesh screens/filters as well as the primary oil filter. Remove the covers using the correct socket size (8mm or 10mm).
    • Carefully take out both the wire mesh oil screen and cartridge-type filter. Clean the screens with solvent (petrol or brake cleaner) and dry completely. Replace if damaged or excessively dirty.
    • Check for any metal shavings or unusual debris–this can indicate internal wear or issues.
  5. Replace or Clean the Main Oil Filter
    • The RMX450Z uses a cartridge-type main oil filter. Unbolt the filter cover (typically 8mm), noting the proper orientation of the old filter as you remove it.
    • Lubricate the new filter’s O-ring with a drop of fresh oil and install it in place. Reinstall the filter cover, tightening bolts evenly to 8-9 ft-lbs.
  6. Reinstall Drain Bolt & Strainer Covers
    • Clean and inspect the drain bolt and oil screen covers before reinstalling. Tighten the drain bolt to 15.5 ft-lbs torque. Don’t overtighten—stripped threads are a common issue in dirt bike cases.
  7. Add New Engine Oil
    • Using a funnel, pour in the recommended quantity and type of new oil (typically 1-1.2 quarts, but always check your service manual for RMX450Z exact capacity).
    • Replace the oil filler cap securely.
  8. Check Oil Level and Inspect for Leaks
    • Start the engine and let it idle for 15-30 seconds. Shut off and let stand for a minute. Check oil level with the dipstick or sight glass, and top off if needed.
    • Inspect around the drain bolt and filter covers for any sign of leaks–the gasket or O-ring may need seating if you spot weeping.
  9. Dispose of Old Oil Properly
    • Take used engine oil to a recycling center. Never pour it down drains or on the ground.
  10. Log Your Maintenance
    • Record the date and hours for the next oil change. Consistent records help with longevity and troubleshooting.

Extra Tips for the 2017 RMX450Z

  • Always inspect the magnetic drain plug (if equipped) for metal particles—an early warning sign of engine distress.
  • Replace all O-rings if they show flat spots or cracks.
  • Never use power tools for reinstalling drain and filter bolts; hand tighten with a torque wrench instead to avoid stripping.
  • If riding in sand or muddy environments, consider changing oil and filter more frequently to prevent premature wear.
