Money no object my choice is an Arai. Here are my personal opinions on the other brands: Simpson - Poor construction and feels cheap Bell - Strong robust helmet but the shell finish leaves something to be desired (I cannot comment if it affects strength) and the visor pivot mechanism is the worst I've seen. Shoei - VERY heavy for a helmet in this price range. Weight should be considered as it is multiplied when heading into a wall. Bieffe - Excellent construction and finish. An excellent value for the money without compromise. On a personal note, they don't fit my head as I would like so I don't own one. Schuberth (SP?) - Nice fit but way overpriced. They only sell helmets because MS wears them. I see no appreciable difference between my Arai and these. Not only that, for those who want the MS lid, it is not even available. The commercial helmet is nothing like what he wears. Might as well just buy yourself a decal and put it on your helmet. Some of the previously posted info is very good. Make sure you try a helmet on BEFORE buying it. Also try different brands. Some brands fit better than others so make sure you get the best fit then worry about style and price.
