New rider on a Piaggio Medley for commuting

Hello everyone,

I picked up a new 2019 Piaggio Medley 125 in October to get me to and from the train station (a few miles away) and then to work (once the weather changes,) but now that the virus has locked us down I find that I should be doing my own maintenance. Frankly, the winter came a bit too quickly, and the bike hasn't even had it's first maintenance, so I need to do this. This shouldn't be problem; I'm reasonably mechanical, but the Medley isn't discussed much in forums, leaving me with a few questions.

The short list of information I'm looking for relates to changing oil and filters; solar battery chargers; and how much information about the Liberty engine can be applied to the Medley. This would get me started.
