In the attached pdf giving some informations about the weight of aftermarket wheels from what I found in the web and also measured my own oem wheels (w/o bearings and everything else except valves and balancing weights 15 grams).
My aftermarket wheels (Power Racing) from Indonesia together are app. 3 kg heavier than the oem's.
Maybe others can jump in and give their infos too.

At least to look for the weight of rims is the half way only, since we also should take a look for that value of the tires because they are the most outside weight.

Here are the weight informations I found and please keep in mind that the weight shown is the average weight for Pirelli tires (the oem should be around 0.5 kg+ heavier).

110/70R17 = 3.691 kg
130/70R17 = 4.740 kg
140/70R17 = 4.900 kg
120/60R17 = 3.778 kg
150/60R17 = 4.947 kg
160/60R17 = 5.774 kg
