Oil Change on a GasGas TXT

Model: Gasgas Txt 125
Part: Engine oil

Video tutorial

Start the bike for a few minutes to warm up the oil, which will become less viscous and drain more easily and quickly. As shown in the video, unscrew the drain plug underneath the bike and collect the used oil in a container (dispose of it properly).

While the oil is draining, unscrew and check the related filter: if it is in good condition, give it a quick clean; otherwise, replace it, ensuring to lubricate the O-ring of the new filter (even with old oil) before installation. Close the drain plug, measure the quantity of oil, and refill the same amount through the upper hole.
