I知 having royal Enfield 1998 model and my rear shocks are in bad shape and I知 planning to change it. Well I知 confused between the hydraulic shocks and gas filled shocks. One of my friend told me that the gas filled shocks are costly which is about 1800RS and it doesn稚 last for long and it has a frequently gas leakage problem and regarding the classic shocks are cheap it will cost RS800/- which is hard but its last for long. Can anyone suggest, if the above points are true. Also which shocks to go with?
