It depends what is your need! If you want a bike with high fuel efficiency at low prive, I would recommend platina 100 cc. It millage is awesome. But remember millage is when you drive it at a speed of 50-60 kmph. A preety good millage of 70-80 kmpl is normal in case of platina though complany claims much higher. We all know on road millage is always less then the idea figure proposed by the company.
Platina is a bike at low price, low maintenance, high efficiency but poor sockers, no disk breaks. And thats fine at such a price.
