I have been trying to lighten up my ice sx I did light brake rotor viper front bumper brackets and took all the foam out from under hood, took skid plate off by my scale It was like 5 lbs But I my self go 5ft 11 and 240 wish i could shed some extra weight. First yr I raced the sled it with me on it at event went 806 total so sled was 581 that was before taken off weight have not put on scale sense. Sled still ran avg 87mph in trail form in 660
