Q. Which one better in terms of reliability, performance & maintenance in long term between Pulsar 125, Honda Shine & Super Splendor?

Yes agree Honda Shine but only if you have good roads. I think Super Splendour would be a better choice as ground clearance is 180mm and this helps a lot if idiotic speed breakers are there of you are in a tier 2/3 city/village roads. I had Conti GT 535 sold it due to an operation in my stomach and bought super splendour. Conti used to touch every where. It’s so irritating specially if you are with a pillion. Happy now.
