If I was to sit on most 600cc bikes, especially ones that are a few years old, I look like a monkey fucking a football...
The new liter bikes are smaller then the old 600s, with that being said, again I know a good bit of people who ride them with zero issues.
sport bikes are small, the idea is to have nothing more then a motor, and tires under you, everything else is for aerodynamics. does it seem weird, sure, but that doesn't mean you shouldn't have any issues riding it.
If anything, the bigger you are the easier it would be to reach the grips, smaller guys have to hunch over to reach them.
