i would strongly recommend pridor for daily rides of upto 70km in a crazy traffic jam city like khi ...
1.Suspension (Shock absorption ability)
both pridor and gs150 hv good shocks ... though pridor hv non-adjustable shocks but a guy with ur height and weight wouldn't encounter any problem with that ....
2.Rising Posture (leaning on front/sitting straight)
gs150 has upright/straight sitting posture ..though, this posture puts very stress on shoulders but put a lot stress on lower back and ur bums will retire soon on longer rides due to this posture on hard seat ... pridor has a very good sitting posture.. its between straight sitting and leaning front, which distribute the weight equally from shoulders to back ... hence no stress on specific body part ...
3.Seat & Seat width.
well suzuki bikes were famous for their rock hard seats until the arrival of rider and gd110 ... but other bikes like sprinter and gs150 still comes with rocks under seat covers while pridor has very nice and comfy ....
also note that handling of pridor is very easy, just like 70, whereas gs150 sometimes gives hard time to handle in compact traffic due to wide handle with bar ends ...if u just want a daily commuter then pridor is best option with good fuel economy too ...if u want power with self starter then gs150 ..
that's my opinion but u should also test the both rides before making any decision ...
