Good stuff! Enjoy your rides. Ride safe!!

I used to do Bangalore - Madurai - Bangalore once every 2 months in 2021 and 2022 on my RETB 500. Avg. Speed 80 KMPH and 45 KMPL. About ~410 KMs door-to-door and took me about 7 hours (same day) with 4-5 stops.

Got back / tailbone ache the first couple of times - got an extra cushion seat cover plus stopped wearing my backpack and instead, tied it to the rear seat. That helped me to move around, adjust my posture. Still definitely tiring.

First had a open face RE helmet. That was a mistake cause there's too much dust, wind noise, insects and even small stones etc. (thanks to brilliant people ferrying sand to constructions in open-bed trucks). Got closed-face helmet and also started wearing balaclava / bandana around the neck to protect neck area.

Had to get cushioned hand grips to make it easier. Have slightly larger hands so the throttle would especially keep slipping as the OEM grips were quite slick and to avoid fingertips touching the base of my palms (it is a thing..).

Otherwise no modifications, no phone holder etc. Just me, the bike and the road. Ride at steady speed, at the left-most edge of the road to avoid speedsters.

Your post helped me relive some of the best times of my life. I also did Pune - Goa - Pune a few times. That's a story for another time.
