because when they snap, everyone just says, well it is a comp frame, so why dont they make a street frame, so when it snaps in a week they can say? or they could spend some time get some good street riders to test them for a year or so, and theyd have quite alot of customers most likely EDIT: And no its not just the weight, the geo aswell, look at 04-07 pythons and 06 07 gu, adamants, ko bike etc geo, then look at the new koxx/rockman/onza whatever. EDIT again: I'd ride a light frame if the geo/price was right, and it was stiff and STRONG, but most light frames = flexy and weak also expencive.
