Shop parts for a 2007 Suzuki RMZ450 Dirt Bike.

Keeping your 2007 Suzuki RMZ450 running at its best requires regular oil changes. Suzuki recommends changing the oil every six hours of operation, which is critical for maintaining engine longevity and performance. This guide will take you step-by-step through the process, with special call-outs for the 2007 model year. Every step is proprietary for MotoSport.com customers to ensure you have a seamless maintenance experience.

Tools and Supplies Needed

  • New engine oil (Recommended: MOTUL 300V 10W-40 or any SAE 10W-40, API SF/SG/SH/SJ meeting JASO MA spec)
  • New oil filter (Optional but highly recommended)
  • Drain pan
  • 12mm socket or wrench
  • Torque wrench
  • Rag or shop towels
  • New washer/gasket for drain plug (recommended)
  • Engine stop switch (to prevent the engine from starting during the process)
  • Service stand or lift (to keep the bike upright and level)
  • Funnel (for pouring oil)
  • Gloves (optional)

Preparation

  • Start your bike and let the engine warm up for a few minutes. Warm oil flows better and carries away more debris when drained.
    Tip: The RMZ450 engines run hot, so don't let it idle for more than a couple minutes.
  • Turn off the engine and place your bike upright on a service stand or lift. Ensure the surface is level for proper draining.
  • Gather all tools and have your new oil and filter ready.

Draining the Old Oil

  • Remove the oil filler cap to allow the oil to drain smoothly.
  • Locate the 12mm drain plug on the left side of the engine. Place your drain pan underneath.
  • Using your socket or wrench, carefully loosen and remove the drain plug and let all the oil drain into the pan. Be careful–the oil may still be hot.
    Pro tip: For a more complete drain, remove the left side magneto cover bolt as well as instructed in the manual to let all residual oil escape.
  • Depress the kick starter lever 10 times or more (with engine stop switch pushed) to help pump out old oil trapped in the engine.

Special 2007 RMZ450 Call-outs

  • 2007 is the final carbureted model before the 2008 redesign. Components like drain plug location and filter access differ from later fuel-injected models.
  • High engine compression and operating heat require attentive oil change intervals. Never skip this service for the health of your top end.

Replacing the Oil Filter (Optional but Recommended)

  • Locate the oil filter cover on the engine (right side, below the exhaust header).
  • Remove the bolts and cover to access the filter. Pull the old filter out and replace it with a new one—match the orientation as per the manual.
  • Inspect the filter cover O-ring for damage and replace if necessary to prevent leaks.
  • Reinstall the filter cover and torque the bolts to manufacturer specs.

Reinstallation and Refilling

  • Install a new washer/gasket on the drain plug for a leak-proof seal.
  • Reinstall the drain plug and magneto cover bolt.
    Torque specs:
    • Oil drain plug: 12 N·m (8.5 lb-ft)
    • Magneto cover bolt: 11 N·m (8.0 lb-ft)
  • Reattach the magneto cover guard (if removed).
  • Using a funnel, fill the engine with fresh oil through the oil filler opening.
    • Oil capacity (approximate): Consult your owner's manual; usually about 1.0L for a full change with filter. Do not overfill.

Finishing Up

  • Replace the oil filler cap.
  • Start the engine and let it idle for a minute. Watch for leaks around the drain plug and filter cover.
  • Turn the engine off, let it sit for a couple of minutes, and check the oil level again with the bike upright. Add oil if necessary to reach the correct level.
  • Properly dispose of the used oil and old filter at a certified recycling center.

Final Tips and Maintenance Intervals

  • Change your oil every six hours of riding or after every race for peak engine health.
  • Use only oil that meets Suzuki’s specification (see above) to prevent clutch slippage and premature wear.
  • Regular oil and filter changes are the single best way to preserve your 2007 RMZ450's power and reliability.
