First off, the Concourse is not your best choice for a commuter bike…it’s pretty heavy for stop and go traffic and obviously you understand that starting with a “liter” bike is not the best choice…as for touring on the smaller engined bikes, it just depends on the speed at which you want to tour…a Ninja 250 can hit 100mph, and they are more comfortable than you might think (yes, the connie is more comfortable…but that should be bike #2 or 3)…if you are planning lots of hiway riding a better choice might be a Ninja 500 or a GS500F which are also pretty “newbie” friendly bikes…both are older tech, but reliable and decently comfortable…they will go a little faster than the 250, but they don’t have to work so hard to cruise on the hiway while still being light enough to commute and learn on.
You don’t want you first bike to scare the crap out of you within your first month…the connie would have way more accelleration than you might be ready for in the beginning, and as I mentioned before, the weight of the bike will surprise you at the worst times…lots of plastic bits that will definately break if you drop it.
My last suggestion to you is get some training…take a basic riders course so that you understand the basics of the sport…don’t forget to wear protective gear…it’s not just the helmet…
Later.
