For all my fellow safety-conscious riders, I gotta share this with you. This handy tool utilizes a database of specific bike models' Gross Vehicle Weight Rating (GVWR), and it assists you in determining exactly how much cargo you can bring along on a roadtrip without overloading your ride. Simple and easy-to-use. The database currently consists primarily of Harley-Davidson and Honda touring models, but it includes select others--and it's constantly growing. So, in the name of safety (and the hopes of deterring preventable accidents on the road), share this with your family and friends:
