From my first GS, a 1981 R80GS Paris Dakar, I fell in perfect harmony traveling the roads less traveled, and some roads not traveled at all.  From the low country to the mountains and in-between, the US and Canada, I rode my GS collections for 30 years.  I can advise you on Tires, Shocks, Windshields, Wheels, Brake and other Upgrades including Accessories, Denali Lighting, Garmin Navigation and much more.  Call me to discuss your GS needs and get your bike ready for the road "OFF" the road.
