I need to replace the swingarm bearings on my Laeger 250R CR500 link swingarm.

Do stock 88/89 bearings server as a good replacement? What about replacing the two chain sliders (small one that goes on the frame and the larger one that goes on the swingarm itself)? Does this use stock 88/89 style or older?

I know that they are discontinued by Honda, so I'm assuming UPP is the way to go.

Lastly the rubber swingarm seals that go on the back where the rear carrier is, what style/year is used there?

Any help or advice would be greatly appreciated.

Thanks!
