Tools and Materials Needed

  • Socket wrench set

Recommended Oil Type and Capacity for 2007 Suzuki JR50

  • Transmission oil capacity: 450 ml (0.5 US qt / 0.4 Imp qt)
  • Recommended oil: Use oil specified by Suzuki or high-quality two-stroke gear oil with the correct viscosity rating for your climate

Note: Always check your owner's manual for the most current and specific oil recommendations.

Step-by-Step Oil Change Procedure

  1. Warm Up the Motorcycle
    Start and idle the engine for several minutes to warm the transmission oil. Warm oil drains faster and carries away more contaminants.
    Safety tip: Ensure bike is in a well-ventilated area. Do not touch engine or exhaust immediately after running—they will be hot.
  2. Turn Off Engine and Stabilize Bike
    Shut off the engine. Place the JR50 on a stable, level surface. Ensure the motorcycle is upright so the oil drains fully.
  3. Remove the Oil Filler Cap
    Locate the oil filler cap on the right side of the engine (refer to your owner's manual illustration). Remove it to allow air in and help oil drain efficiently.
    Clean around the cap area to prevent debris from falling into the crankcase.
  4. Position the Drain Pan
    Slide your drain pan beneath the drain plug at the bottom of the transmission case.
  5. Remove the Drain Plug
    Using your socket wrench, carefully loosen and remove the drain plug. Allow the oil to flow completely into the pan.
    Hold the motorcycle upright if necessary to ensure a complete drain.
  6. Inspect and Clean Drain Plug
    Wipe the plug clean while oil is draining. Inspect the plug and washer for metal debris or unusual particles.
  7. Reinstall the Drain Plug
    Once oil has drained entirely, reinstall the drain plug and tighten securely—do not overtighten. If you have a torque wrench, torque to specification noted in your owner's manual.
  8. Remove the Oil Level Screw
    Find the oil level screw (located near the filler cap). Remove this—it's a check point to determine when the new oil is at the correct level.
    This allows excess oil to escape when refilling and prevents overfilling.
  9. Add New Oil
    Place a clean funnel in the oil filler hole. Pour fresh oil slowly until it just starts to trickle from the oil level hole (where you removed the screw).
    Requirements: 450 ml (0.5 US qt). Be precise.
  10. Replace Level Screw and Filler Cap
    When oil begins to escape from the level hole, stop filling. Reinstall the oil level screw tightly, then replace and tighten the oil filler cap.
  11. Wipe Down, Clean Up, and Inspect
    Wipe any spilled oil from the engine and frame. Check for leaks at the drain plug, level screw, and filler cap. Dispose of old oil responsibly according to local regulations.

Model-Specific Call-Outs for the 2007 Suzuki JR50

  • No Engine Oil—Transmission Only: The JR50 is a two-stroke dirt bike, so the engine uses a pre-mixed fuel and transmission oil is the only oil changed in this maintenance step. Do not confuse this with engine oil for 4T models.
  • Proper Oil Level is Critical: Overfilling can lead to pressure loss, leaks, or clutch issues, while underfilling will accelerate wear.
  • Be Cautious with Drain Plug Threads: The aluminum cases on the JR50 can strip easily; never force the drain plug and always tighten gently.
  • Change Oil Regularly: Suzuki recommends the first oil change after one month of use, then at least every six months, or after heavy riding conditions for maximum protection and longevity.
  • Use Only High-Quality Oil: Cheap or wrong viscosity oils may lead to clutch slippage or gearbox wear.

Frequently Asked Questions

  • Can I use automotive oil?
    No. Use only oils designed for motorcycle transmissions; automotive oils lack the required friction properties for wet motorcycle clutches.
  • How do I know if I overfilled?
    If oil flows freely from the level screw hole, you have the correct amount—any more, and you've added too much.
  • What if I see metal in the oil?
    Some metallic sheen is normal, but heavy debris could indicate wear. Consult your dealer or MotoSport.com if concerned.
