I saw an article in a mag at borders yesterday in either superbike or TWO about 2 identical 2005 r6's. The name of the articlw was "the japs have been building engines wrong for 20 years"! They took 2 2005 r6's and detuned one and left one bone stock. The detuned one ran reground stock cams and a few other things to lower the redline and peak power output but really beefed up the midrange. I think 10 journalists rode the 2 bikes back to back and everybody but one picked the detuned r6. It was only marginally slower in the quarter mile but roll on's and engine performance was better for the street. The detuned bike was about 4 seconds faster in all the roll on tests. Has anybody done this to their 600k4 for better street riding? I found this article very very interesting in a motorcycle magazine. 9 out of 10 journalists said that the detuned r6 was better in every aspect than the stock bike. More midrange and peak hp #'s at a much lower rpm. I was astounded by this article. Someone else had to read this article. Please if you have, what mag was it? Also the sprockets were the same on each r6. Stock!
