You guys are doing it wrong. I would no more let my wife tell me I can’t have a motorcycle, than she would let me tell her that she can’t have shoes...lots and lots of shoes. A motorcycle is part of the Melas package, no debate allowed.
Btw, I wouldn’t start on anything smaller than a 250. Anything smaller handles more like a scooter and less like a motorcycle.
I do think a 150 is a good starter bike, 250 can be a bit hard for a beginner to handle
