Thanks for the input so far. Yes, from what I have heard and read, Howard says the best way to set up the front is to use the larger 2014+ fork tubes with new triple trees. From what I recall from a thread on the big HD forum, he feels the pre 2014 smaller forks are not sturdy enough. A friend of mine from another forum with a 2010 RG did the 2014 fork conversion with the Ohlins set up at Howard's, and was actually the first one to do it. He is quite pleased with his set up, but no way would I spend $3,000 to go that route.
If Howard is selling just the FKC 101 set up, I'm sure it would be with a nice discount, as he usually does for us forum supporters of his. So, cost would be a factor since with a discount, the FKC 101 could potentially be up to $500 cheaper vs the Traxxion AK 20's.
I wouldn't think the difference would be night and day, or even largely noticeable between the FKC 101 and Traxxion set up, but that is just an assumption. If they are close in feel and performance, I'd gladly save the few hundred and go with Ohlins.
I'm not a real aggressive rider, and am maybe 70/30% solo/two up. But, I do want the benefit of a more confident feeling front end that has the ability to corner awesome when the mood strikes. Lots of time to research and decide though- riding season is still about 3 months away.
