It probably comes down to rider against rider. The difference in weight is minimal - 787 to 842 manual to F6B or 800 to 842 DCT to F6B. And remember there is a 7 lb difference between the fuel tank capacity 5.5 gal vs 6.6 gal. So 48 lbs manual to F6B or 35 lbs DCT to F6B. Plus there is more rotational drag on the new wing from a larger tire that weighs more. Dyno # are coming out a tad less on the new model than the F6Bs. Either way the are both quick and if your concern is which is quicker than you are looking at the wrong bike. Love my F6B, but once they straighten out the front end design issues I might consider getting one.
