Ok was browsing the Yamaha website and l found a link to Yamaha Racing Parts, which is a load of tuning parts for the R6 and R1. Not cheap, but I thought they were quite cool. I wondered if HRC did the same and stumbled across this:

Can anyone shed some light on it? Obviously not a road bike, but can joe public order one of these? If so, does anyone know how much they would cost?
