The DR-Z125 is 72.2 inches long, 30.3 inches wide and 30.5 inches high at the seat, which gives a ground clearance of 10.2 inches.

      The DR-Z125L is 74.2 inches long, 30.3 inches wide and 31.7 inches high at the seat, which creates a ground clearance of 11.4 inches. The extra wheel size also allows for an increase in weight. The DR-Z125 comes in at 194 lbs., and the DR-Z125L weighs 196 lbs.

    Systems

    • The braking systems on the DR-Z125 and the DR-Z125L are the only other change between the two models.
