Cruiser = fat, lazy, slow. A bike which you can see the cows in the fields and the totty at the bus Stop.
Sports bike = out right fun, fast and nimble. Cannot see any thing bar blurs and startled cows. Hot totty laugh at you in leather all in ones sat in fetal position.
So if you want to go round corners fast buy a sporty bike,if you don't and buy a cruiser then don't bitch about your choosing of such bike.
