I have to admit that I chose my Braking wave rotors solely for their, erm... aesthetic value (i.e. I thought they looked cool). Imagine my surprise when I flipped through the pages of the latest issue of Performance Bikes, and found their test, aptly named, "Do wavy discs work?". It turns out they do. They (PB) swapped the standard discs on an R1 for the exact same disc type that I'm using, and the wavy beauts actually made the big Yamaha stop quicker. Significantly quicker in fact. They suffered less fade too. What was it they used to say at the Bauhaus school? Function follows form? or was it the other way around?
