Dear Fabio, for motorcyclists of your stature we recommend motorcycles that have the saddle less than 80 cm from the ground, even if the height of the seat surface doesn’t tell everything, given that its shape matters a lot at the point of connection with the recesses in the tank.
If you don’t like custom bikes, a category of accessible bikes is that of the classics. Moto Guzzi V7 e Triumph Street Twinfor example, measure at the saddle 776 and 783 mm respectively, according to what was detected by our test center.
If you’re not in a hurry, even less high is the highly sought-after one Royal Enfield Meteor 350: we measured the seat just 750 mm from the ground.
Finally, if you lean towards more modern lines, among the medium naked bikes the lowest are the evergreen ones Suzuki SV650 (792 mm surveyed) and the Kawasaki Z650 (with the saddle at 796 mm).
