There was a road test in one of the big bike mags back in 2004 when the Kaw V2K was bike of the year.
The "Moving Engine Stand" only beat the V2K in the quarter mile by less than a second; which is way less than the rider skill factor difference.
I have, still own and occasionally ride my nice 2004 V2K. Believe me, although fast for a V-Twin, it ain't even close to an R3R - in ANY respect.
