In this guide, we will provide instructions for changing the transmission oil on the Aprilia SR 150 scooter. First, place the scooter on its centre stand and begin unscrewing the drain screw located under the transmission cover, allowing it to drain into a container for about ten minutes; then unscrew the fill screw, allowing the oil to drain into a container for another ten minutes. At this point, refill with new gear oil suitable for your transmission (as indicated in the user and maintenance manual).
