Here is the bike suggestion for you.
I would prefer to have a Honda CG125 to you. Because its very comfortable, stylish, durable, commuter, having resale ability, market value, easy availability of spare parts, and most important thing SPEED, it has a great pick up and and amazing speed of 120 kmph. if you have altered your Honda cg125 then you can gain 140--150 km.
I had Honda cd 70 2008 model and i sold that 6 months ago. now i have a HONDA CG125 1998 model. its more and more good than the 70. i have just spent a few thousand on it and now its working like a cheap road runner and I've planned to do not sale it ever until my end.
I love HONDA !!
