NOTE

Gross Vehicle Weight Rating (GVWR) and corresponding Gross Axle Weight Ratings (GAWR) are given on a label located on the frame steering head.

NOTE

Wet weight is the total weight of the motorcycle including fuel, oil and primary fluid. GVWR is the Gross Vehicle Weight Rating (maximum allowable loaded vehicle weight). GAWR is the Gross Axle Weight Rating (maximum allowable loaded weight per axle). Load capacity is the amount of weight (including the rider) that can be carried on the motorcycle without exceeding the GVWR.
