progressives springs

Postby Keef » Wed Dec 03, 2014 7:47 am



Hello, I am getting ready to change my fork seals. (1997 GL 1500 Aspencade) I was told when I bought the bike that it had progressives springs
in it.
Is there a way I can tell for sure that this is what it has?
Also I was told if you have progressives springs in the front, you don't have to ride with air in them. Is this true?

Thanks any & every one!!

Oem and progressives both single spring. I believe Progressives have a a tighter coil..but hard to tell..look at their site and see if the pics match yours or the Oems in the parts fiche. As to no air needed up to you..read the progressive instructions on their web page.
HAD LOTS OF GOLDWING 75-83
NOW INTO 1500'S..RIDING A 1998 SE

FAIR WINDS,

The only way to know for sure is to pull the springs out and look. Factory springs have a constant coil rate for almost the entire length, with a slightly compressed bit at the end:



Progressive springs have a few inches of compressed bit at the end:



And yes, you can (and in most cases should) run zero air pressure in your forks with Progressive springs installed.
