The R6 is a 599cc beast, produces 122bhp of raw power and an amazing ride. But yet, it has nothing in front of the 1190 cc, produces huge 173 bhp through its amazing V-twin engine, clocks around 300kph and one of the most extreme road legals. R6 is a much better day to day and a track day quite so often, and the RC8 is a track beast, with the most mean look ever.
