I'd like to make a couple of points which are based on my opinions only. When and if you go shopping/testing/ motorcycles, there will be the temptation of buying a crotch rocket type bike. (originally called cafe racers, which are based on actual road racing geometry) You know the type; handlebars mounted on the fork tubes, foot pegs mounted rearward, laying down riding position. They usually have fairings but not always. They caught on big time because of the "race look". Heck, even the guys who ride road racers for a living don't ride them for more than a typical race duration. Most guys who buy these for the street didn't think about this before buying. I feel sort of sorry for them when I see them leaning on the bars. Of course if you're not actually racing, you practically HAVE to lean on the bars most of the time which is contradictory to the bike's design and forces you into a semi "push up" position the entire time you're riding. In other words, these bikes are not good commuters or tourers, or, for that matter, even for joy riding, as far as comfort is concerned. I would even say they are unsafe as typically ridden. So unless you're into racing or looking like a racer, look for something powerful and good handling with an upright seating position that doesn't strain your body after 30 min of riding.
Another type which is in vogue these days is the "cruiser" type motorcycle. These are virutually all trying to copy Harly Davidson design which is ancient but currently "in style" due to the supposed machismo image projected.
Steering head at chest level, grips at almost shoulder level, seat sunken down. A geometry which is about as bad in the other direction as the crotch rockets. Yes, you'll feel comfortable on one but, in my opinion, not in as good control as when seated on a well designed motorcycle.
Since these two styles make up what is probably a majority of all new motorcycles today, it seems it's difficult to find what I would call a proper design. I walk into a motorcycle shop and it's either crotch rockets, cruisers, or dirt bikes.
Now I haven't actually shopped for motorcycles in a good while but I have seen glimpses of some contemporary ones that appear well designed. Either pure street bikes or I also like the dual sport design which is popular now.
there's my three cent's worth.
