SUZUKI genuine part.
- GS750 and GS1000, GSX1100E and GSX1100S and other classic bikes use this.
- Suzuki doesn’t have this setting for all models, so feel free to adapt it.
- Replacing the window feels really satisfying! (*´ω`*)
- For oil-cooled models, use the next size up: 11971-33210
Suzuki doesn’t have this setting for all models, so adapt it well.

I completely forgot about it until someone asked.
I was wrong to assume every bike would have this setting.
It was listed in the parts list for my GSX1100E.


This part is a bit tricky to find if you’re not used to it.
It’s listed on the clutch cover page as shown in the image on the right, so try to find it.
I’ll note down some approximate dimensions.



The outer diameter is around 25φ, with a press-fit depth of about 6mm.
When you polish or repaint the clutch cover, replacing this looks really sharp.
