I'm going to have to rebuild my forks in the next couple of weeks and figured I may as well pop some new springs in too.

For between £80-£120 I can get myself progressive springs from a plethora of manufacturers, all of which appear more or less the same, I'm unsure why a progressive spring from Hagon would be much different to one from Wilbur?

Still within that budget Ohlins do a range of linear springs in various spring rates.

I get the difference from a technical point of view between the linear and progressive springs, but when it comes to road riding I have no idea which is better under which circumstances and why?

If I go for linear how do I work out what spring rate to go for?

Thanks for the advice

I was always under the impression that the CORRECT linear rate springs are the best bet.

Wilbers are pretty helpful and also do linear springs. Drop them an email with details of your bike, your weight, riding style and luggage/pillion details and ask what they'd recommend.

I found that the progressive springs that I tried in forks of my Exup1000 very difficult to set up and there was no best compromise with oil level/air gap/spring preload.So I went for Ohlins springs which are linear and straight away I was able to find the best setting Thumbs Up

Then,for my R1,I bought Ohlins springs that,when static,seem too hard.But once underway,they work as I wanted Thumbs Up

The differance in the springs are noticeable

As well as Ohlins springs,I have heard of good feedback about https://www.k-tech.uk.com/roadrace.php
