I dont own an Honda shine of my own but by friend has it and I use to drive it daily. The main problem with the honda shine is that it does not have good performances. The bike do not provide much of a satisfaction in terms of comfort in riding. The main problem is its vibration, the bike has good vibration when the speed reaches 50 to 60 range.
Gear changing is not smooth, and u need to give choke and start it. The bike provide good mileage in the starting months but later on even after servicing there is no improvement.
