Rx 100 for GF

I myself am a new rider, bought speed 400 after a discussion on this sub. It’s been like a month and I have learnt to handle the power of this beast( o learned on this bike only. Past few week I have been teaching my gf to ride and she is taking it like a pro. I want to gift her a Yamaha rx100. The reason for it, her father whom she lost at 7 used to ride a black rx100. And she has some very sweet memory of riding with her father sitting in front of him. Now my questions are Is it a good bike for a 20 year old female ? Does it need too much maintenance? I can find it for 1.3 lakhs to 1.5 lakhs, does it justify the price ? Also what should I pay for something like this ?
