Nice to know that u r enjoying experince of Both GS 150 & Storm 125,
If u wana go with Wider tyre like CG Dlux or storm's tyre than i wud recomend u to change rear rim of ur GS as well as its stock rim size is 1.60 X 18 which can serve tyre size upto 3.00 X 18 while for wider tyres like 3.25 & 3.50 X 18 or 90/90 X 18 u need rims size 1.85 X 18 or 2.15 X 18. So u can use rim from CG Dlux or Storm 125.

Are u guys sure ur bikes are equiped wid 19 size tyre? if yes then tell us how u guys install 19 # tyre on 18 # rim & where did u found 19 # rear tyre?
Faisal pls dont ruined beauty of ur bike by installing front Cowling/Headlight of CG Dlx it wudnt suit on GS. BTW if installed on Storm 125 its looks more attractive than on CG Dlx it self.
