Engine Oil Replacement

Model: Sym Symphony 151
Part: Engine oil

Video tutorial

Before starting the engine oil replacement on the Sim Symphony 151 scooter, ensure your bike is in a stable and secure position to protect the operator's safety. This precaution should be taken whenever performing maintenance on any motorcycle.

Next, place a container suitable for catching oil beneath the oil drain hole located at the bottom of the engine block (as shown in the images). Using the correct spanner, unscrew the bolt that seals the drain hole and allow all the old oil to drain out. Refit the drain bolt and open the filler cap for the new oil. Once this operation is complete, you're done!
