To replace the fluids on a Derbi GPR 50, first identify an oil with the appropriate specifications. Once found, open the oil drain plug located at the bottom of the bike, as shown in the video. After collecting the used oil in a container, close the plug and top up. To top up the coolant, locate its cap: this is found between the fork and the fairing, on the left side of the bike. Once located, insert a tube into the reservoir and pour in the coolant using a funnel.
