To change the gear oil on the Beta Xtrainer, loosen the drain plug on the transmission casing, located at the lower rear of the bike. Once this plug is removed, collect the used oil in a suitably positioned container. After all the oil has drained out, close the drain plug and top up the oil: this can be done by adding the necessary amount of oil through the breather located on the right side of the vehicle.
