I know I will get some crap thrown my direction for some of my following comments, hopefully the pitchers will "throw like a girl". Some people see Harleys as status symbols that make them seem bigger than they are. And yes, I have seen women riding Harleys that I would call "spinners"(ducking now).
Here in WI, Harley Davidson rules the market, by a very large margin. I own one. I love it. Been super reliable, looks great, and with a few tweaks, rides great. But I can't tell you how many times I've overheard a HD salesman or HD rider makes the "real bike" comment to those that ride something other than HD. Hell, the salesman that sold me my HD back in 2006 asked me that once after pulling up to the dealership on my GSX-R. I had to remind him he sold me one already. I don't frequent that dealer any longer due to poor customer service.
That said, and as I said, I love my HD. It has a 27" seat height. I am 6'6" tall. If I stand up over the bike, my crotch is nearly a foot above the seat. I have other bikes, too. Most much taller. I feel comfortable on all of them. You just need to remember what each bike is designed for. But I've never had a concerned thought about sitting too low on my HD. In fact, being so close to the pavement makes everything see faster.
As for engine power, remember that HP is only part of the equation. With an HD or similar large V-twin engine, the torque plays in a lot more than on something like my sport bike. On my HD I can pull away from a stop without even thinking. Hell, I can roll away without even giving the engine throttle. On the sport bike I need to be a little more diligent with the throttle and clutch.
All pros and cons. Just remember what the bike is designed for and have fun riding.
