St4 Forks - Or Are They?

Discussion in 'Technical Help' started by BrianST4, Nov 25, 2022.

  1. I have a 'new to me' 1999/2000 ST4. I checked the factory settings for fork preload (16mm) as I wanted to get back to standard settings. Checked mine and they were 10mm so I thought I'd go back to 'factory'. Book says between 10mm and 25mm with standard setting at 16mm. Wound it up and at 16mm it seemed to tighten up and not want to go any further. Forks felt much too firm!! Have wound it back to 10mm.

    Question, have I got 'non-standard' forks? I am told the previous, previous, owner had made some changes, e.g. fitting an ST4S alloy swing arm, so I am wondering about the forks.??
     
  2. The fork tubes on the ST4S were gold
     
  3. Thanks Chris. Mine are definitely Silver. Wtf??
     
  4. How are you measuring it?
     
  5. Thanks Bradders. The answer is 'the wrong way'! Double checked with the book and they are as they should be! Old age kicking in obviously!!! :worried: :):):upyeah: Thanks again.

  7. Yes , but not on the ST4 which doesn't have nitrided tubes. The upper legs themselves are silver on all ST models.
