Harley has been in the hunt with AFT production twins as I recall, and any wins they get these days are due to just plain hard work because the competition is much, much heavier than just 3-5 years back... AFT has brought the old AMA flat track racing back from the grave and any wins there are certainly earned... the ancient Harley 750 won because it was about the only game in town, but Vance & Hines have helps with good sponsorship and when you see a Harley win now (or any other brand for that matter), regardless of class, I'm pretty sure they worked at it...
