Hey guys today I am going to review royal enfield thunderbird twinspark. the look of the bike is totally unique compared to other royal enfield. the ridding position of the bike is awsome because of its handle bar. the bike is very comfortable to ride. you can take this bike for long rides. as it is royal enfield the mileage is not very much its around 25 to 30 kmpl. the otherwise the bike is very good. the roadgrip of this bike is also very good. the service expenses of this bike is little high and its spare parts is also very expensive.
