GS150 is a very good bike and a powerful one... may be which you tested has some fault werna chalany men kam nahi hai or smooth ride ki kiya baat hai ...
Ager ap ka kisi weekend per lahore ka chaker lagay tu zuror apko RP check kerwa don ga ... but RP shyid apko pasand na aye it do not have that Power Pul jo apko CG men milta hai... GS is better I think.
CG kio bech rahay hai any thing u found wrong in it ?
