The more time you spend in the motorcycle world, and chatting with other riders, the more you realize our struggles are pretty similar.
Not exactly the same; most other riders I meet are, after all, quite a bit taller than me. Or, at the very least, they have longer legs (which helps). For the record, I'm a little over 5'3" and have an extremely moto-discouraging 27-inch inseam, so you have some idea of my perspective. My arms aren't long, and my hands and feet are also pretty small, too.
But at the end of the day, the thing about any vehicle you're going to spend lots of time in (or on) is that it needs to be comfortable and accessible for whatever your measurements are. In cars, you can pretty easily adjust the driver's seat to accommodate multiple drivers who are different heights. On bikes, it's also possible, if not quite as simple.
The thing is, you'll have to make modifications to that bike if you want it to fit riders of significantly different heights, in most cases. Depending on whether you do it, have a knowledgeable friend do it, or have a shop do it, you'll have to spend different amounts of time, effort, and money to make it work.
Over time, more motorcycle manufacturers have made accessory low and tall seat options available, on top of whatever the standard seat option is. Kawasaki even took this to a greater extreme some time ago, introducing its Ergo-Fit system to make easy adjustments to handlebars and foot pegs, in addition to saddles, so riders could more easily dial in the correct motorcycle fitment for them. And that's absolutely to their credit.
