The updated list of motorcycle seat heights now contains seat heights for 2013 Harley-Davidson, Victory, Honda, Suzuki, Kawasaki, and Yamaha models. In addition, I have added seat heights for some popular electric motorcycles: Brammo, Vectrix, and Zero. At this writing, I have added seat heights for 2012 BMW and 2013 Indian motorcycles. The data are arranged in a table from lowest to highest seat height. All motorcycle seat heights are given in inches. There is a listing containing all models taken together as well as individual lists for each make.
