Ramq Posted April 7, 2022 Share Posted April 7, 2022 (edited) Hi! New member here! I recently bought a used GSXR1100W (1993) fork to convert my gsf1200 MK1. However, I started service these today, and the legs appear to be different from the inside? Does anyone know what’s going on here? Did the previous owner replace one leg for a newer model?

Jaydee Posted April 7, 2022 Share Posted April 7, 2022 (edited) My guess is previous fork builder misplaced a metal spacer tube (probably fork apart for a while waiting on seals and bushings) and then fashioned a new one out of a durable plastic. Can't see why the plastic replacement wouldn't be up to the job if its a good hard grade. Check it for any signs of stress or fracture to be on the safe side. Looks to have a bit of though gone in to it as he has a seat to support the tube. I'd almost bet theres a seat on the other end too to support the main spring.

TonyGee Posted April 7, 2022 Share Posted April 7, 2022 yeah agree, looks like a bit of improvisation Quote Link to comment
Simbec1863 Posted April 7, 2022 Share Posted April 7, 2022 (edited) I’ve rebuilt a lot of forks and older boat anchors RWU forks have plastic preload spacers as well as more modern upside down Suzuki model forks The holes are for the pins in the spring compressor for detaching the adjuster from the damper tube Edited April 7, 2022 by Simbec1863 Quote Link to comment
Ramq Posted April 7, 2022 Author Share Posted April 7, 2022 Thanks for the replies! So the plastic spacer seems completely after market? I though it looks too nice to not be oem.. Quote Link to comment

gray711 Posted April 7, 2022 Share Posted April 7, 2022 I’ve got an OEM K6 spacer sat on the bench. Here’s a pic to confirm they used plastic in later forks. Quote Link to comment

Fantastic thanks! Now I know where it’s from and that it’s at least safe to keep using it! As you can see below, the plastic one is slightly longer. But since I’m putting them on a Bandit anyway, I think it won’t matter much. Quote Link to comment
