Royal Enfileld is good to use. It is helpful for back pain people .It cure the back pain. It gives more sound.
Bad things:
In the royal Enfield when we travel in highway at high speed engine began to stoped so it is a one problem. So, we should had a race bike engine to royal Enfield .we should improve our engine into more powerfull one. We should improve the 260cc into 600cc. It gives more and less petrol to drive the bike
