I didn't even notice that. I wonder how much lighter it actually makes the wheels.

I think there was a discussion on aircooled rd site and the consensus was they were too fragile.

Don't forget that these were one of the first production "alloy" wheel and Yam were still learninig their craft.

That's why I spent over £400 on flanged ally spoked wheels, much lighter (and sexxy!)

It would take a proper engineer, but I would think you could drill out at least some. I am a rock climber and some of the gear has this done, now by the manufacturer, to lighten the gear. It doesn't reduce the soundness of the structure. You would just have to really do some hard core engineering.
