It sounds like Luck SC has never riden before. Since you asked for opinions, here's mine. Buy a dirt bike first and learn how to ride and fall on the dirt. Although there are some differences in dirt versus asphalt, techniques are pretty similar. You don't get too many second chances on the road and you can bet you will bust your ass a few times while learning. After getting the basics down, the Honda Nighthawk is an excellent bike and is 750cc.
