if any incident happen than fracture of human body must happen while GS 150 has much more features having very high engine power but still not compete with GTO 125, If any Incident happen than GS 150 suspension gets damage and no little affect on person riding that bike and frame also completely safe due to the great design of GS 150 by engineers ... comparatively GS 150 is much much better then cg 125 or delux 125
Truly said ............ This type of incident (i.e. Head on collision with another bike) happened to me, When i'm driving my bike Suzuki sprinter eco 2014 with at least 90km/hr on a bumpy road (yes due to very good handling and shock absorbers of suzuki's bike, you can drive it at this speed) .With the grace of almighty Allah, I got only a Abrasion (without any blood) on Hand only. Hence this is true for all suzuki bikes not only for GS 150.
Newton's 2nd law " F=ma " is applied in this case as bending of front rim and shocks decelerate the bike and influence of force (here collisional) is reduced. Moreover I think more height and bending of Handle bar saves the hands of rider too.
