Anyone having experience about Wilbers & Hyperpro fork springs ?

Wilbers fork springs are the German's weapon of choice, if I did not have a spring makers almost in my back garden I would have bought Wilbers since the American company got all parochial & refused to ship to the UK.

One thing to note is that if you intend to use emulators or PD valves to set up the forks properly you need to buy straight wound springs NOT progressive wound springs.

suggest you read my fork spring swap on my site

Hi yamaha_george !

I have read your fork spring & PD valves swap on your site.

At this time I feel that my economy is not letting me go for the full fork mod with the PD Valves,
so for now I will buy a pair of progressive fork springs.

* Hyperpro is a Dutch company.
* Wilbers is a German company.

Which is the best ?

...or maybee I should put it this way : Which manufactur make the best fork springs for the FZR600 (3HE) ?

As I said I would have bought the german and if i was short of funds I would buy the non progressive set as otherwise i would be having to buy YET another set of springs when I had money for the PD valves BUT then I am tight fisted .
