Where is the battery on a Yamaha Riva 50 - XT 125 X Yamaha Motorcycles

Will you please provide the VIN number so I can look u the exact number?

There were 2 models that year called the Riva 50, but later the other one eventually came to be known as the Riva/Razz 50,

check the oil level.If it is a normal engine lubrication set up the it will require oil pressure to put the light out which means that as soon as it starts or during cranking the light will go out and it will start. If the oil light is an indicator of low oil level then it will not start until you put oil in the emgine . Check the switch for correct opertion.

Start by checking the battery. For a wet (lead acid) battery:

VOLTAGE (OCV) STATE OF CHARGE
12.8 100%
12.6 75%
12.3 50%
12.0 25%
11.8 0%

For an AGM battery:

VOLTAGE (OCV) STATE OF CHARGE of AGM Battery
12.7 V 100%
12.6 V 75%
12.3 V 50%
12.0 V 25%
11.8 V 0%

So all batteries are pretty much the same.

Then after seeing what surface voltage you have an recharging if low, the next step would be to get a load test done on the battery and clean and tighten the battery cable attachments at both ends of the cables. If it is not a problem here the next step would be to diagnose the starter and the starter system for which information as to exactly what happens when you activate the starer is necessary
