Part: Transmission fluid

Video tutorial

To change the gear oil on a TM Racing 125, you need to loosen the drain plug located at the bottom of the engine block: once this plug is unscrewed, you can let all the used oil flow into a suitably positioned container. Once the oil has completely drained, you can access the upper front part of the engine block: here you will find another plug that needs to be removed.

From this vent, you can top up by adding the necessary amount of oil.
