Renewing the fork oil on your 2013 or later BMW F800GS
Changing the oil in your forks is just as important as any other fluid in your motorcycle. As you ride your bike, your fork oil slowly gets dirtier and loses it's proper oil viscosity. This can result in premature wear and tear on the forks as well as contribute a rougher ride. It's much easier to spend an hour or two of your time along with $15 of fork oil, than have to replace parts in your forks (new forks will run you $2400 at the time of writing).
Note 1: The specific bike shown is a 2013 F800GS using WP forks, older bikes have a similar process, but use a different style of forks (Marzocchi).
Note 2: The tools and materials used are by personal choice and are not due to any affiliation with any brand.
Fluids Required:
SAE 7.5 wt Fork Oil - we need about 1220 milliliters or 41 ounces (1.3 quarts)
Tools Required:
- 24mm socket (preferably 6-sided)
- T25 star (Torx) bit
- T30 star (Torx) bit
- T45 star (Torx) bit
- E12 external star (External Torx) socket
- 17mm socket
- 13mm open end wrench
- Ratchet(s) that fit the above
- Torque wrench
- Suitable way to raise the front wheel and keep the bike steady
- Container to catch the used oil
- Your least favorite shirt/rag
