Have a 2013 f6b and it runs great but i dont find it to be any faster then my 07 hd fatboy that i had a bit of motor work done to. I feel they were pretty much the same and here is how i know. My neighbor has a big dog with a 117 on it. With the fatboy i am exactly even with him in pretty much every race we do and pretty much exact same result with the f6b.He cant get away but i cant pass him either. Sold the fatboy as i stopped riding it when i got ths honda. Oh yea i had also changed the compenster sprocket to a diff tooth amount on the harley for a tad more low end,that probably helped as that thing did pull like a frieght train.And yea i spent/wasted way to much money to make that harley move the way it did. I have also owned a honda cbr 600 and a triumph street triple in the last 5 years .Those are fast especially the cbr !!! This is all just my humble opinion and i love this bike. Would i like a bit more hp and torq? Oh yea.
