I took bajaj avenger on rent when I went to Goa in january 2015.
I have traveled entire north Goa and south Goa with this bike and let me tell you it was too comfortable for me to ride for a long stretch.
People having back problems and still want to ride should prefer this bike. Also the fuel consumption of the bike is low.The handling and control is quite good.
The look of the bike is also pretty awesome.
