I own this bike for over then three years and I am very satisfied with it.Lately I use super 98 octan(no lead) petrol and I sense more power from engine.During this time I didn´t have any problem with engine,except with some electrical parts(turn signalization relay,speedo instrument)which is probably due to long time use.Occassionally I do trips for about 500 km longs,and never left me down.I like it very much driving it and because of this bike now I´m hooked to Honda bikes.Honda rules!!! P.S. Honda cb 250 rs will allways be my nr.1 bike!
