ZRX forks pre-load adjustment
Posted: Thu Apr 04, 2024 2:44 pm
Hopefully this sneaks under the radar because they are routinely fitted hereabouts and they are on a Gpz 1100B.
I have zero knowledge of modern forks, the J is the newest bike ive owned
The ZXR (edit; should say ZRX) forks have approx. 10mm or so, blue pre-load adjusters on top. There are about five / six annular rings machined on them about 2mm apart.
Question; from fully up to fully down, how much could you expect this to raise the front end up. In my ignorance i will say i have the view that pre-load adjusters only serve to make the forks longer but i could see that at some point along that scale it may also compress the springs causing them to be effectively stiffer. I dont know what the pitch of the thread is that is attached to the adjusters but cant think that adjusting between two rings let alone a total of perhaps 10mm will be felt or detectable or serve any useful purpose.
Does anyone know how much uplift, (extension) full adjustment would give and whether in fact they do make the front end more harsh the further you go.
I know the rake and trail i need and have searched the ZRX forums and cant find this particular adjustment described in any detail, except to mention what works for different people.
