Congrats, you will love the bike more each time you ride it. After owning over 45 bikes myself, my "new to me" GS is my favorite. It does it all!
You can also expect a massive VISA bill due to spending thousands in "Farkles."
"Farkles": Accessories, either wanted or needed to make your bike more functional, cooler, faster, better off-road, etc. Usually includes a GPS, XM radio, engine guards, fender extenders, very expensive shocks, spotlights, expensive saddle, more expensive metal saddlebags, tank bags, tail packs, various windsheilds depending on time of year, hand guards, headlight guards, oil cooler guards and/or anything that is made by Touratech, ADV Rider, Wunderlich or Al Jesse! Don't ask me how I know this!
