How many motorcycle CC's do you think I can handle?

For a beginning biker. I know starting small is best. I am 5'10" 165 lbs. I'm assuming the 1000+ CC is for expert bikers who can handle that weight. I've been looking at bikes around 750-800cc. Thanks
Added (1). Thanks for the answers everyone. I'm looking to get a cruiser motorcycle. More specifically I'm looking for a Kawasaki Vulcan or a Honda Shadow.
