myn OZ F1s mag wheels weigh 4.5kg (without tyre) each.. stanard oz f1s weigh around 7.5/8kg iirc
iirc i think they weigh a kg hevier than mine if magnesium, 5.5kg. and 9/10kg standard.
all above are without tyres.. add on 7-9kg for a tyre
Ive had a mag one and a standard one in each hand. There isn't that big a difference. I owned 4 of each at the same time. The oz f1's a light wheel as standard.
Iirc the cup racers used the mag ones for strength rather than weight
i thought the mag ones were no where near as strong as the cast ones
