G'day,
I splashed out and bought some Ikon springs. Well they arrived today, and tomorrow I am going on a 300km or so ride, and I can't wait to see how they change the ride. I noticed out of the box they are longer, maybe 2 or 2.5 inches longer, the coils are further apart, and the progressive part of the spring is different. Not sure if the new spring is a specifically different design, or the old spring just got squished that much..
After installing, I set them to softest, and through the ride I will probably harden up as I go along.. :yes:
These are the local stockists, I bought mine for $168, delivery included. Very nice people.

It is difficult to tell in the photo, but the new springs looks smaller in diameter.
Is the new spring diameter large enough to properly seat on the damper rod at the bottom of the fork?

Wow, that's pretty expensive. I can get Wurth springs for less than 100€. Thing is, shipment to Australia would probably erase the difference.
Randy, my apologies for the question.....
I have a set of your fork valves which I plan to install in a few weeks and will be putting new springs in as well. I understand that with the valves i need .85kg/mm springs. I rang a local bike suspension guy to order some linear springs and explained I was putting in some valves as well however he reccommended a progressive spring (Wilbers) saying they are the exception and would still be a better option than the linear spring.
Would you reccommend the linear springs or some Wilbers progressive springs with your product? (sorry if this is spelled out in the instructions, I have dont have the valves at my place right now)
Cheers,
Camo

Did your local suspension guy offer you the progressive spring rates? i.e. Starting (lightest) rate to final (hardest) rate?
If not I cannot even offer you an answer. If you have those numbers I can see if they will work.

Thanks Randy for the help. Just had a chat to the guy and after asking three times he couldnt give me a straight answer so I gave up....... Might stuck with the liner spring rates. Cheers

That is my recommendation. If the progressive springs are too soft to begin with, the valves will not stay seated. If they are too stiff the IAT bypass cannot operate and the valves will be very harsh riding.
Also, the fork oil is very important. the only two oils that I found that have the proper HVI ratings are the Motul Factory Line 5wt and Amsoil 5wt.
Here is the full write up on the fork valves, spring and fork oil specifics:

Have the Ikon springs in my FJ and have 140 thou km on them. Found 15wt oil and light dampering works well.
Thanks Randy :good2:
G'day,
Randy: They do seem a little thinner in the picture, but they seated well, and I did'nt have difficulty in screwing in the fork tops, and the ride difference is greatly improved! Minor bumps are much smother, less weave when I go round bumpy corners with the suspension set to soft. (the roads round here are bad and soft is better if one is riding every day)
Roverfj1200: Thanks for the tip, I was using 15wt before on stiff, now the forks are on soft I will stay with 15wt. Took me awhile to settle on that, tried 20wt, 10wt, etc.
cheers, Gareth
well after taking the new springs for around 500 kms, I have to say I am very impressed. The best comparison to the old springs is a nearby road that is a very bumpy surface, and I usually do it at 120kmph at the most, and still feeling safe. Today I took the same road with the new springs, and found that the bike handled so much better, I was averaging 140 kmph and feeling safe and confident.
Great investment, and cheap considering the benefits.
cheers, Gareth
