the above picture is of ax4 which is available in south america .. it hv few changes and also the seat is noticeably different and rigid, not flat like gd110 ...
there is a reason why gd110 looks small, even slimmer than 70,hv short distance between raider and handle, low height, ultra soft seat and sensitive suspension ...we know gd110 is specifically designed for philippines market ....
now the fact is filipinos are light weight and small with average weight of 54kg and average height of 5 ft 4in , which is lighter and shorter than the average height/weight of people from many other countries in asia .... so obviously suzuki engineers focused exactly on those ratios while designing this bike ... so my wild guess is anyone above those ratios would face problems like seating position, low mileage etc ... and that would not be the fault of suzuki engineers .. pak suzuki should hv aware of this ...
P.S
on a lighter note i think that's also the reason why it's kick is touching to footrest in the end .. cause engineers never thought a person with 5.4 height could do it ...
