Well i still ride my storm every day .first thing i noticed was the weight the RSV is a hell of a lot lighter and the engine is a lot more free er revving than the storm but i think the storm has a bit more bottom end ,ridding position is a lot better than a standard storm i was expecting it to be uncomfortable but its not for a sports bike .the millie has more power and is lighter so it goes a bit faster , handles better but i tell you that the storm is a bloody good bike and the engine in it is great had mine 5 years and love the engine it just the rest of itis a bit old hat now . ( 9 out of ten for the rsv 7.5 for the storm
