I'm 5'9 and 135 lbs (I skate and excercise) so I am no where near your size so I can't comment on that. But I can carry my wife on it easy and id guess she is 165ish. Though she won't tell, and I've never caught her on a scale (funny how that is lol). Oh and the fz6, and sv I wouldn't call a beginer bike. You can start on it but the 300 will make you better faster.
