Sportbikes have only one riding position. On a cruiser, you can ride normally, or put your feet on the highway pegs, or put the back of your ankles on the highway pegs, or put your feet on the passenger pegs behind you (as if you were on a sportbike). So, 4 riding positions, which means more comfort and more circulation to your legs on long rides. Plus, insurance will be lower than on a crotch rocket, and in general, you will look more civilized, and enjoy a broader view of the road than if your head were just above the gas tank , like on a sport bike. I vote cruiser.
