Well, if you want to buy under 150 cc bike then Bajaj Discover 135 is best in all around aspect but if you are style conscious and want something different in good package then go for Honda CBF Stunner.  And if you want best mileage at 125 cc but good styling too then look for TVS Flame 125cc.

Thanx a lot dudes.  Surely look wise Stunner will get the top rating.
 But have anybody faced with any maintenance hazard for Honda bikes....... I mean how is the service centre and maintenance experience?

Thanks a lot Ricky and Mitra for sharing your views , but I am really surprised to find  comments from only two people.

hi
i own a discover135 for the past 2 years. the bike stuns with its performance of engine but is short of the 5th gear. it can race at 90kmph with a good handling.
the area where bajaj fails are its electronic departments and cheap quality materials.
I have changed self start relay, clutch switch relay, bulb at the rear, speedometer cable (3 times !!!), trip meter clamp, even disc plat in the front was with a defect.
Remember the bike looses its quality after a year. bajaj cant be compared to the honda or yamahas's quality and long life.
I have the idea to change over to the honda stunner or a yamaha fazer.
