While it may be cool to look at a bike that weighs less than a gallon-and-a-half of milk (well, ok, it's cool to me, and it's my damned website), you don't want to know how much it'd cost.

Put it another way... it's far easier to shave five pounds off the engine that drives the bike than it ever will be to carve that same five pounds off what is basically expensive sticks with wheels on. Doesn't mean I don't want it. Bad.
