Below are the steps to perform the service on the transmission by changing the oil on the Sym Symphony 125 scooter. First, place the scooter on the central stand and begin unscrewing the oil drain bolt found under the transmission, allowing it to drain into a container for about ten minutes; then unscrew the fill screw and top up with new transmission oil (in this case, it is inserted with a syringe). Once topped up to the maximum level, start the engine, topping up again if necessary.

What Does the V-Belt Light Indicate on a Yamaha NMAX Scooter and How to Remove It?

If the V-BELT light has illuminated on the instrument cluster of your Yamaha NMAX scooter, it means it is time to replace the drive belt as it has exceeded the relevant interval.

Once this is done, you can manually reset the light by following the procedure shown in this tutorial. First, turn on the instrument cluster, then repeatedly press the left button on the dashboard to reach the service interval in question.
