If you own a BMW R65 motorcycle, you know how important it is to properly maintain and service your bike. One critical aspect of maintenance is keeping the front forks in good working condition. The forks are responsible for absorbing impact and providing stability while riding. In order to ensure smooth operation, it is crucial to regularly check and replace the fork oil.
Here are the steps you need to follow to fill the fork oil in your BMW R65:
1. Preparation:
- Gather the necessary tools and materials, including a torque wrench, socket set, fork oil, and a clean cloth.
- Put on protective gloves and ensure you have a clean working area.
2. Remove the forks:
- Lift the front of your BMW R65 off the ground using a motorcycle stand or a jack.
- Loosen the triple clamp bolts that secure the forks to the frame.
- Remove the front wheel and brake calipers.
- Slide the forks out of the triple clamps and carefully place them on your work surface.
3. Drain the old oil:
- With the forks upside down, remove the fork caps using a socket and a torque wrench.
- Allow the old oil to drain completely into a drain pan.
- Clean the fork tubes and other components thoroughly with a clean cloth.
4. Fill with new oil:
- Pour the recommended amount of fork oil into each fork tube.
- Slowly pump the forks up and down to remove any air bubbles.

Once you have gathered all these materials, you’ll be ready to move on to the next step of filling the fork oil on your BMW R65.
Step 2: Prepare the Motorcycle
Before you start filling the fork oil on your BMW R65, it’s important to properly prepare the motorcycle. These steps will ensure a clean and safe working environment:
1. Park the motorcycle on a flat and level surface. Make sure it is stable and won’t tip over during the process.
2. Put on safety goggles and gloves to protect yourself from any potential oil spills or splashes.
3. Clean the fork tubes with a rag to remove any dirt or debris that may have accumulated. This will help prevent contamination of the new fork oil.
4. Remove the fork caps using a wrench or socket. Be careful not to damage the caps or the surrounding area.
5. Place a drain pan underneath the fork tubes to catch any oil that may leak out during the process.
6. Pump the front suspension a few times to remove any remaining oil in the forks. This will help ensure that you get an accurate measurement when filling the forks with new oil.
Once you have completed these steps, you’re ready to move on to the next step of filling the fork oil on your BMW R65.
Step 3: Remove the Forks
Once you have drained the old fork oil, it is time to remove the forks from the motorcycle. Removing the forks will make it easier to clean and inspect them, as well as add the new fork oil.
Start by securing the motorcycle in a stable position. Use a stand or lift to support the front of the bike, ensuring that it is secure and won’t tip over. This will provide a safe and stable working environment.
Next, locate the bolts or nuts that secure the forks to the motorcycle. These are typically found at the top and bottom of the forks, near the triple tree and axle. Use the appropriate tools, such as a socket wrench or Allen key, to loosen and remove these bolts or nuts.
Once the bolts are removed, carefully slide the forks out of the triple tree. Be cautious as you handle the forks, as they may be heavy and greasy. It may be helpful to have a friend assist you in holding the forks as you remove them.
Set the forks aside on a clean and flat surface. Take this opportunity to inspect the forks for any signs of damage or wear. Look for leaks, corrosion, or worn-out seals. If any issues are found, it may be necessary to repair or replace the forks before continuing.
With the forks removed, you can proceed to clean them thoroughly. Use a cloth or sponge and a suitable cleaning solution to remove any dirt, grime, or old fork oil. Wipe down both the inner and outer surfaces of the forks, ensuring that they are clean and free from debris.
Once the forks are clean and dry, you can proceed to add the new fork oil. Refer to your motorcycle’s manual or the manufacturer’s guidelines to determine the correct amount and type of oil to use. Use a funnel or syringe to carefully pour the oil into the fork tubes.
After adding the fork oil, reassemble the forks by carefully sliding them back into the triple tree. Secure them in place by tightening the bolts or nuts. Be sure to torque them to the proper specifications to ensure they are securely fastened without being overtightened.
With the forks properly reinstalled, you can proceed to the next steps in the process of filling the BMW R65 fork oil.
Step 4: Drain the Old Oil
Before filling the BMW R65 fork with new oil, it is important to drain out the old oil first. Follow the steps below:
1. Lift the Front Wheel
Using a motorcycle stand or lifting device, raise the front wheel off the ground. This will allow you to access the fork and drain the old oil more easily.
2. Locate the Drain Screws
Find the drain screws on the bottom of each fork leg. They are typically located towards the rear of the fork tubes. Use a suitable wrench or socket to remove these drain screws.
3. Drain the Old Oil
Once the drain screws are removed, allow the old oil to drain completely from the fork legs. You may want to place an oil pan or container under the forks to catch the oil and prevent a mess.
Note: It is recommended to fully extend and compress the fork a few times while draining the old oil. This will help remove any residual oil and debris from the fork internals.
4. Clean the Drain Screws
While the old oil is draining, take the opportunity to clean the drain screws thoroughly. Use a clean rag or solvent if required to remove any dirt or grime that may have accumulated.
5. Replace the Drain Screws
Once the old oil has completely drained out and the drain screws are clean, reinstall them back into their original positions. Ensure that they are tightly secured but do not overtighten them to avoid any damage.
By following these steps, you have successfully drained the old oil from the BMW R65 fork and are now ready to fill it with fresh fork oil.
Step 5: Fill with New Fork Oil
Once you have completely drained the old fork oil and replaced the seals and dust covers, it’s time to fill the forks with fresh oil. Here’s how:
1. Consult your owner’s manual to determine the appropriate amount and type of fork oil for your BMW R65 model. Different models may require different amounts and viscosities of oil.
2. The fork oil can be poured into the forks either by using a funnel or by removing the fork caps and pouring it directly in. If using a funnel, make sure it is clean and dry to avoid contaminating the oil.
3. Slowly pour the fork oil into each fork leg until it reaches the recommended level. You can measure the level by using a dipstick or by using the markings on the fork tubes.
4. As you fill the forks, make sure to pump the forks up and down to eliminate any air pockets that may have formed. This will ensure proper lubrication and function of the forks.
5. Once you have filled both forks, reinstall the fork caps and tighten them to the manufacturer’s specifications.
6. Clean up any spilled oil and wipe down the fork tubes to remove any excess oil.
7. Double-check the oil level and visually inspect for any leaks before putting the bike back together. Properly maintaining and filling your forks with oil will help provide a smooth and safe riding experience.
