Progressive springs information

[sunburnedaz]

I have been going though vision parts trying to clean things up in the garage so I can find things. I think i might have found some progressive springs in a fork. Does anyone know the free length of the stock springs? I don't want to take mine apart.

You could look it up - it's in the factory workshop manuals

Stock free length:
   US 82=461mm
   US 83=476mm
   EU 82=451mm
   XZ400=406mm

There was a manual for progressive springs floating round ages ago but I never snagged a copy.

In the early 2000's we found that the stock springs were way too soft . Some added progressives and some added a 1.5 inch spacer on top of the stock springs. You should  have a set of stockers in the front end parts I sold you. You have one more still here!

 I have a pair of Progressive springs for my Vision, they are 21" or 533mm long. no spacer needed.

I used them until I decided to install Gold Valves whitch add about 3/4" to the height of the damper rod. I didn't want to cut the springs so I used the stock 83 springs with more preload.

The ride height is good but it could use alittle stiffer spring.
