I prefer XRM Motard
Based on my experience..
I own a XRM 125 DS (Modified and Lifted)
Fuel Efficiency - they are all the same (I guess, I have tried dual sport, rs and wave)
Durability and Reliability - comfortable for long distance, not like the RS, I experience back pain for long rides with RS(because of the handle bars)
Speed - The three can reach more than 100 kph.
I have nothing to say for the pros and cons.
