I am not sure of the weights but I do know those bikes came in at a bad time. They were developed a few years ago as freeride bike to fill a hole. The problem is the very next year freeride bikes as we know it 6 inches travel a little heavy but VERY burly came into the picture. The left that frame out in the open. It isn't burly enough to be a real freeride bike and isn't light enough to be a xc bike.
All that said 4.75 is fine for non racing xc. That is a pretty low range on the travel of bikes today. It is also designed with low bob in mind so it is pretty stiff.
