If you are looking for a bike who give almost a mileage of 80 to 90 you can go for the bajaj platina who almost give the above average mileage about 90 kmpl and which is very much for a 100cc bike.
Platina is good to buy for office work only because of the mileage. I don’t like the look of the bike at all. The only thing in this bike is mileage thats the only reason people buy this bike and its is not as much as successful product of bajaj as compare to the other bikes.
Over all it is a ok ok bike fir middle class people but I wouldn’t recommend you this bike only because of the mileage.
