I have purchased this bike one month back & just feel great about my decision of buying it as it was in taken short notice. I was inspired by friend who had already purchased & using it. As he had said Efficiency >50, drive smoothness, comfortable its was all coming true.
I also just got it serviced it from Kothrud Suzuki which improved its drive smoothness & gear shifting. One can drive this bike at speed of 30 KMPH in 6 th gear & feel just sitting in a volvo. Just dont think over for bikes like Pulsar, Apache, etc. There is no problem regarding gear shifting, chain noise, atleast on plain roads.
Take a test drive & you will surely take home this value for money bike. Little concern is of city handling & rough roads but I hope one can manage as it is for some short distances.
