the hitch carrier has a few advantages and disadvantages. It is more difficult to load and unload. The bike will get dirty--I'd look into a Geza cover. However, some states have a lower speed limit if you have a trailer and higher toll fees. so I like the hitch carrier when I can. I don't have one for sport bikes, but I've carried my scooter and dirt bikes on them. If I had a moto tote or similar, I'd use it for a sportbike.
