Racetech springs are progressive wound for 49mm, so (according to Ricor and fabrik8r) you won't realize the full potential of the Intiminators. In fact, fabrik8r seems pretty convinced that progressive springs prevent the Intiminators from working as designed.

AFAIK, Traxxion is the only company making single rate springs for 49mm forks...unfortunately, they're still figuring out the right specs.

Fortunately, I don't mind being their guinea pig. I'm learning a lot about my bike and how its suspension works.

 

I have ricor 12.5" sport tune. The are great solo or two up and have never bottomed them out. No more jolting, I fly over railroad track at 70+. They are great in the twisties or on the freeway. What I wasn't expecting is how much better the bike handles the crosswinds. You gotta do the intimidators...there were a lot of road surfaces that made me feel uneasy with the way the stock forks felt. Now the front end is full of confidence.

 

So you have the Ricor sport tune shocks on the rear & Ricor Intimidator springs in the forks?

Rogert that. I'll keep an eye out for your results and will let you know how the Traxxion springs work out for me.

 

The intimidators are drop in disc that go under your spring. I am still using the stock spring but you will be shocked to see what those intimidators do even with the stock spring. I am also running 10w amzoil shock therapy fork oil. That HD fork oil is crap IMO. and yes to the ricor shocks in the back. There are other options, let your pocketbook be your guide.

Brian never tried a single rate spring in his dyna (when he had it) He liked the racetech but you really can't compare the two unless you've tried both.

Suspension is forever...wait a couple of weeks and do it right or just try the intimidators with the amzoil fork oil...you will be surprised at the difference in just that mod.

I hear you...that's why I still have my stock springs in. With the intimidators alone it is so much better I'm just waiting for Squid to get it all figured out. No hurry.

There are tons of people on here using the stright rate traxxion springs on thier harleys...Nobodys really figured it out for the dyna 49mm forks yet.
In fact when racetech didn't have the 49mm dyna forks listed on thier website I asked Brian what he used and the application was actually for a v-rod.

Traxxion makes both single rate and progressive type springs..you just order what you want

Just the Intiminators, Amsoil Shock Therapy, and stock springs are waaaaayy better than stock, so I don't think you can go wrong in your choice of the springs. I'm actually pretty happy with just the switch from #5 to #10 Amsoil. If Dan doesn't hurry up with those .90kg springs, I may just keep the stock springs...

ok, maybe not, I'm too far into it to stop now.
