Q. What about its pillion ride and is it suitable for long distance touring - SuperSport?

Yes, it has a pretty comfortable seat for a pillion, grabrails are an accessory. Seat cowl comes as standard for S model and is removable, for standard model it's available as an accessory as well

I have done rides upto 600km to and fro and the pillion was comfortable, rest depends on the person also. But in general its pretty decent back seat, wide and well cushioned.
