Bayliss showed what he could do in that race.
Most underrated rider of the last two decades, IMO. Would've been awesome to see him and CS on the Duke in 07.
Just to add a personal favourite with my total bias as far as underrated goes ........ McCoy.
In Oz terms, what Bayliss has put back into the sport in Australia is (from my immediate memory) unmatched from all of those that we have produced throughout the last 30 or so years.
Others with less of a profile (Broc Parkes for example) give back, but without the profile of Bayliss their 'pull' is limited, but Bayliss is involved from juniors, to the ABSK (or whatever it is now called) and in all forms from Supermoto to dirt track, he is everywhere.
