Swingarm bearing dimensions - 1990 GSXR1100

[ACTAngler]

Can anyone tell me the dimensions of the swingarm pivot bearings on a 1990 GSXR1100 please? I know the pivot shaft is 20mm diameter so bearing spacer ID is 20mm, but also need to width and ouside diameter of the bearings.

Save me pulling the fucker apart again, thanks ;)

Jst out of curiosity Shane, whats the swingarm pivot width? Any chance of runnin a tape over it, including the dust covers???

As near to 230mm as I can measure with a steel ruler, thanks mate.

Turns out the 2004 swinger I want to fit is the same width, but I need to sort out something for the bearings (going from a 25mm pivot shaft on the 2004 down to a 20mm on the 1990). Any ideas?

Cheers mate!
A reducing top hat style spacer would be the go i would think!

Thanks for the advice guys. That Ron Ayers site is fantastic!

Might have a go at pulling it all apart again this weekend for a proper mock-up fit, work out if it's all going to work or not.
