Has anyone tried the Progressive Fork Springs or Shocks?

Yes . GET THEM . Fast Eddy will fix you right up . The fork springs really made a difference and then I got the 412's and it really made a difference . Rides like a different bike .

+2, A major improvement on the ride and handling of the bike. Fast Eddy well that says it all!!

Hi Guys, I,m running 440s on rear and progressives up front with shell 20 synthetic fork oil 01/07 speedy, this is a whole new ball game, expensive but worth every penny,,,done 18,000kms, 12,000 miles and rapt, go for it, cheers Tadpole..

Scott , the choice between 412's and 440's would be your "total riding habit weight" . For example - I usually ride alone with little gear and I weigh only 176 , so I run the 412's . If yer a big ole hunky dude and ride a big ole hunky dude on the back , like Yota , you may wanna get the 440's .

Then there's the issue of stock height , lowering , ect . Talk to Fast Eddy - he can fix ya right up , 11.5 , 12.0 , 12.5 .

I have the 440s on the rear and progrssive springs in the front and consider it some of the best money I have spent on the bike. The difference in ride is fantastic, but even more important is the significant improvement in the way the bike handles. Go for it. I have yet to hear of anyone here that regrets buying them.

yes...pick the right rear shocks, slip in the new fork springs and enjoy!

Hey Boys & Girls.
I'm looking for new fork springs, but wondering which dealer is best. Specifically, do some dealers sell the fork springs with new spacers vs. others that sell 'em without any extra bits?

This looks like it's just the springs:

These are $10 more but look like it includes new spacers:

Any input would be appreciated!

Just a thought regarding popping in progressive fork springs. When I first bought my hagon progressive springs, initially I just opened up the fork caps and did a one for one swap with the stock springs.

Well the other day I decided to replace the fork oil which had been in since new. The dealer suggested the air gap for the Hagons should be 140mm and the oil I should use is about 10wt.

So before I replaced the oil with the above specifications, I measured the fork sag of my bike just standing upright by itself, and once replaced I measured the sag again.

Well it turned out that by replacing the oil, my forks were raised up approx' 1 inch or 25mm.

I haven't had the opportunity for a long ride yet but tomorrow I go on a 3 day road trip so I'll determine the results then but I can say that on the small rides I have had, the ride is considerably better than before and considering I have 25mm more travel, why wouldn't it.

Of course, it makes sense the 25mm or 1" more travel is due to change in the air gap specifications ie: stock springs 166mm compared to 140mm for the progressives, though I thought the difference may have been due to the different type of spring.

Anyway, if you are like me and just popped in new progressive springs, you MAY I stress, MAY find that you lose 25mm or 1" of travel at the same time.

Mind you, I've been riding with the old fork oil specs for thousands of K's and my Sheila handled as well as I thought she should. Maybe I'll find out her handling now is even better.
