Q. What mileage do you get in city? and is it comfortable - Apache RR 310?

I am getting around 36kmpl as of now which is a blend of highway and city traffic. It depends on the way you are driving. It is stable and comfortable but yes there will be some amount of heat dissipation near thigh and ankle which should not bother you much during high traffic condition like it may in duke 390 or RC 390. The radiator fan will turn on number of times to cool the system and you can easily hear it. Even after switching off the engine it will run for few seconds which is good for cooling the system efficiently.

I get a mileage of about 28 approx in City in semi traffic condition and yes I feel very comfortable , except during heavy traffic where it gets heated up pretty bad

In semi traffic , i am getting a mileage of 27 kmpl but if you talk about high traffic , it gets heated up damn high.
