Yes, most bikes are bought as toys, but you can use it as a commuter as well. And, there's no reason to not go on trips across the country, as long as you have a comfortable bike
My friend, have you driven the East Transvaal passes, or the Drakensberg, Lesotho on the way to the Lesotho Highlands water project? Behind the wheel of a good steering car, it's huge fun. You don't even have to hit the speed limit, just go around a corner as fast as you are comfortable.
Testing your abilities, pulling some Gs... Ahh, bliss. Potholes and bad drivers are one of the risks, but not many things in this world, especially those that are fun, doesn't have a risk.
