I'm about your height and your weight and have rode the meteor, it's not as hard to ride as you think. You'll probably feel the weight at slow moving traffics and u turns but it's easily compensated by the lovely lovely motor and smooth gearbox. The only thing I felt is personally the footpegs seemed too forward set, so test drive meteor and classic both, they have the same engine.

If you still worry about the weight try the hness cb350, it honestly felt like a bicycle despite being like 180 kg. Very easy to ride.

Jawa is the easiest and the lightest but isn't as smooth as the other two but it still has its own charm.

I feel like all these are better than the avenger but ofc they cost more also ig.
