anybody know what the spring rate is for the ikon fork springs?

[steamfitter]

hi all. working on tuning my suspension and was wondering if anybody knows what the spring rate is for the ikons? i weigh 160lbs. so spring rate is a concern. saw the racetech calculator and it says i should be at .920 kg/mm. just wondered where the ikons came in at

There is no spring rate because they are progressive.
It would actually be correct to say that you would have to plot the spring rate on a graph through the compression range.
This is actually rather easy to do if you really need to.
whether it is linear or not I do not know. sorry

There is no spring rate because they are progressive.

They quote spring rate(s) for their progressive springs for rear shocks here:-

7610 series & 76 series Shock Absorber Springs

There are two figures quoted (IE: 95-174) the lower of which is for the softer or closer windings and the other for the harder or wider windings.

However I could find no ratings for their progressive front fork springs.

I assumed that he was talking about fork springs because he mentioned Race Tech.

actually i was referring to ikon springs, i was just bringing up the spring rate calculator on their website. got a reply from ikon today. for reference if anybody cares:

ikon progressive fork springs for bonnevilles:

spring rate is .622017 kg/mm to 1.050291 kg/mm

ikon 7610-1602SP8 rear shocks for bonnevilles:

spring rate is 1.93743 kg/mm to 4.28274 kg/mm

The OP mentioned fork springs in the thread title, I just thought it odd that they quoted rates for rear springs on their site but not fork springs.
