This was posted on the quality helmets discussion. As for the weight of the SparX one review said that they only tested 4 helmets that were heavier and all where the high dollar brands. So for weight $140 verse $450. Here is some stuff about the saftey rating on the SparX.

Posts: 7 many people feel that the ECE 22-05 is a way safer rating than the snell rating. The ECE 22-05 is a batch test and is supposedly more realistic in its methods of testing than the snell test.
And i also read that DOT only helmets are safer than snell because the snell approved helmets are specifically designed to pass the snell certification. And if many people feel that the snell tests are unrealistic, than anyone who buys a snell helmet is essentially buying a helmet whose only realistic purpose is to pass a snell test. When we ride, were not performing a snell test. We dont ride to replicate the conditions of any test.
personally, I just crashed an icon domain helmet. Scuffed up the shell real bad... and dont wanna take chances on the eps being damaged. I keep hearing recommendations towards the ECE 22-05 rating, and my next lid will most likely carry this rating. Im currently looking at the shark helmet line. The new SparX line also has ECE 22-05 lids and they retail for about $100-150 tops.
