I think Zeus and Andy have picked up on something about the angular design, it definitely was the design language of the time.
The first twin light 'blade and 916 were fairly angular...I suppose as a "faster" sleeker looking design after all those late 80's square, slab sided wardrobes!

I like the sculpted rounded shapes (and the lower screen) found on the MC28, which particularly pick up on the Rothmans lines around the seat unit. It looked just like the GP bikes of the day, epic! And the single sided swingarm is genius, even if the performance gain was negligible.
