Doing some measurements, and does anyone know the width of the RM Wrist Pin bearing and Year that is used?

18x23x22 mm does this sound right?

99 RM250 but they used the same bearing for many years. suzuki part number is 09263-18016 and you are correct on the size it is 18x23x22

I'm doing a top end soon. What washers are needed to use the rm bearing?

Dez you would use some fabricated Alum washers, I don't know who is making them now. My self I am liking the idea of using Metric Thrust bearing washers instead, 31mm ID x 18mm OD x 1mm with stackable 1mm shims washers.
With the gab being increase from OEM width of 22mm to RM bearing width 18mm, I am wondering if these would work? OEM thrust washers are 2mm wide with a 1mm instep.

Those thrust washers will fail and f your engine up. They are not made to withstand the type of load for a wrist pin there only good in compression against the rollers. Stick with the billet aluminum washers.
Have you ever had to replace a set because of wear?

So the washers would have to made out of 7075 aluminum then?
Carl are the washers used for Thrust or only as spacers to center the rod end in the piston?
