Shop parts for a 2014 Honda CRF250R Dirt Bike.
Changing the oil in your 2014 Honda CRF250R is essential maintenance to keep your dirt bike in top condition. Doing it yourself not only saves money but helps you get familiar with your machine. This guide, exclusive to MotoSport.com, walks you through the process with all the details and model-specific tips.
Tools and Supplies Needed
- 12mm socket (for drain bolts)
- 8mm socket (for oil filter cover)
- Socket wrench, extension bar
- Oil drain pan
- Clean rags or paper towels
- Funnel
- New oil filter (recommended to change every oil change)
- Recommended engine oil (Honda GN4 10W-40 or equivalent high quality 4-stroke oil)
- Recommended transmission oil (Honda HP Transmission Oil or equivalent high-performance 80W-85 or 10W-40 for wet clutches)
- Replacement crush washers (optional, but a good idea to avoid leaks)
- Torque wrench (for accurate reinstallation of bolts)
Preparation Steps
- Start the engine and let it warm up for about 3 minutes. Warm oil drains more completely and carries more debris with it. Shut off the engine and allow it to sit for another 3 minutes before starting the oil change.
- Position the bike upright and stable—use a stand if possible.
Step-By-Step Oil Change Instructions
-
Locate the Drain Bolts
- The engine oil drain bolt is located on the underside of the right side of the engine.
- The transmission oil drain bolt is located below the shifter on the left side.
-
Drain the Oil
- Place your drain pan under the engine oil drain bolt (right side, 12mm). Remove the bolt and let the oil drain completely.
- Once finished, reinstall the bolt with a new crush washer if available. Do not over-tighten—just enough to be snug and leak-free.
- Repeat the process for the transmission oil drain bolt (left side, 12mm), located behind the shifter. Let the oil drain, then reinstall the bolt with care.
-
Replace the Oil Filter
- Remove the oil filter cover (8mm bolts) on the right side of the engine.
- Carefully pull out the filter–there is a spring behind it, so be prepared for it to pop out.
- Install the new filter, making sure the spring is positioned properly. Reinstall the cover and bolts evenly.
-
Refill with Fresh Oil
- Use a funnel to pour engine oil into the filler cap on the right side of the engine. For the 2014 CRF250R, Honda recommends about 0.8L (after oil/filter change), but always check your owner's manual and fill gradually.
- Add transmission oil through the filler cap just above the shifter on the left side. Recommended capacity is about 0.75L.
- Do not fill to the precise listed amount without checking the oil level–it is common for the listed spec to slightly overfill the crankcase. Instead, fill until oil begins to just seep out of the check hole for each side, if equipped, or check the sight glass/dipstick.
-
Check Oil Levels
- Start the engine and run gently for 2–3 minutes. Shut it off again and let it settle.
- Recheck both engine and transmission oil levels. Top off as needed so both are at their correct marks.
-
Clean Up
- Dispose of the old oil and filter properly at a local recycling facility.
- Wipe up any spills and double check for leaks around the drain bolts and filter cover.
Model-Specific Tips and Considerations for the 2014 Honda CRF250R
- Separate Oil Compartments: The 2014 CRF250R uses separate engine and transmission oil systems; never swap or combine.
- Drain Plug Location: Both plugs are somewhat hidden: engine oil is underneath, the transmission plug is behind the shifter—removal of the shifter may help if access is tight .
- Oil Capacity Nuance: Owners and expert techs caution that Honda's listed capacities may overfill slightly, so always check the level through the sight glass or check plug during refill rather than blindly pouring the entire listed amount .
- Filter Installation: When replacing the filter, watch for the spring behind the filter element—be sure it's seated correctly before replacing the cover .
- Tightening: Do not overtighten the drain bolts or the oil filter cover. Use a torque wrench to match factory specs (typically 12-18 ft-lbs for oil drain bolts).
- Oil Choices: High-quality synthetic or semi-synthetic oil is recommended in high-performance four-stroke motocross bikes–Shell Rotella T6 is a popular owner choice, but Honda GN4 or equivalent is always safe .
Final Checks and Riding Ready
- Double-check that all bolts and caps are secure.
- Confirm oil levels after your first ride and top off if necessary.
Proper oil maintenance is one of the best ways to ensure your 2014 Honda CRF250R delivers top performance and reliability for years to come.
