How to Change the Oil in a 2007 Honda CR250R: The Ultimate Guide

Changing the oil in your 2007 Honda CR250R is essential maintenance for ensuring your dirt bike runs smoothly, maintains performance, and prolongs engine life. This proprietary guide for MotoSport.com covers the tools you'll need, step-by-step instructions, and model-specific tips every CR250R owner should know.

Tools & Materials Needed

  • Drain pan
  • 17mm socket (for drain bolt)
  • 10mm socket (optional, for side coverings or guards)
  • Socket wrench
  • Torque wrench (recommended for tightening to spec)
  • Rubber gloves
  • Clean rag
  • Funnel
  • Measuring cup (Ratio Rite or similar)
  • Replacement oil (Recommended: Maxima MTL Transmission Lube, 10W40 or appropriate API grade SF or SG 4-stroke oil, SAE 75, 80, or 85 weight)

Honda CR250R Oil Specs & Capacity

  • Oil Type: API grade SF or SG, 4-stroke multigrade oil (preferably 10W40, 75W, 80W, or 85W)
  • Oil Capacity: 650cc (0.69 quarts)
  • Torque Specs:
    • Oil check bolt: 84 In-Lbs
    • Oil drain bolt: 22 Ft-Lbs

Step-By-Step Instructions

  • Warm Up the Engine
    • Start your bike and let it idle for several minutes. This thins the oil and allows it to drain more easily and thoroughly.
  • Position the Bike
    • Put the bike on a stand so it's level. This ensures all the oil drains properly.
    • Place a drain pan under the engine to catch the old oil.
  • Remove the Drain Bolt
    • Using your 17mm socket, carefully loosen and remove the oil drain bolt on the underside of the engine.
    • Let the oil completely drain into the pan—be patient and allow several minutes for best results.
    • Remove the oil filler cap on the side cover to allow air in; this helps oil flow out more easily.
  • Optional: Remove Side Guards or Skid Plate
    • If your CR250R is equipped with a skid plate or side guards, use a 10mm socket to remove as needed for better access.
  • Inspect and Clean the Drain Bolt
    • Check for any metal shavings or debris on the magnetic tip of the drain bolt (if applicable).
    • Wipe off the bolt and the sealing surface on the engine.
  • Reinstall the Drain Bolt
    • Thread the bolt by hand to prevent cross-threading, then tighten with a wrench.
    • For best results, use a torque wrench and tighten to 22 ft-lbs.
  • Add New Oil
    • Ensure the bike is still perfectly level.
    • Measure out 650cc (0.69 quarts) of fresh oil using a Ratio Rite or other accurate measuring cup.
    • Using a funnel, pour the oil into the fill hole.
  • Proper Level Check
    • The side case typically features a small oil check bolt. Remove this bolt; when filled to the correct level, oil should just begin to trickle out of the check hole.
    • If no oil comes out, add a small amount at a time until it does. As soon as oil flows out, reinstall and tighten the check bolt to 84 in-lbs.
  • Finish Up
    • Reinstall the oil filler cap securely.
    • Start the bike and let it idle for 1-2 minutes; check for oil leaks at the drain and check bolts.
    • Turn the engine off, let sit for a minute, and recheck the oil level. Top off if needed.
    • Dispose of used oil responsibly at a recycling center.

2007 CR250R-Specific Call-Outs

  • Oil capacity is 650cc (0.69 quarts) per fill. Always double check on the side case for factory-stamped capacity, but use the oil check bolt for accuracy. Avoid overfilling—the CR250R transmissions are sensitive to oil level for clutch and gear performance.
  • Do not overtighten drain or check bolts. The aluminum cases are easily stripped if over-torqued.
  • Use only motorcycle-specific transmission or gear oil–do not use automotive engine oil as friction modifiers can negatively affect clutch engagement.
  • Always verify that your transmission operates smoothly after each oil change by running through all gears on the stand before riding.
