I pm'd you with the sizes of the Beta Sachs CC cartridge bushes. I think they might fit. Only thing is that you might have to adjust the end gap a bit.
Can you measure (in mm) the sizes? I have my crap Sachs CC forks of a Beta to bits and the piston looks very similar. If the sizes are the same you can get the bushings from a Beta dealer. PM me I'll get my callipers out in the mean time.
Fork Bushes
Innteck does them. The link can help as a guide.
Should be able to find Innteck as they are US made.

Main thing for me is the suspension, had worn out CC forks and after warranty replacement same story. I fitted KYBs after. Plenty of other niggling issues too that could easily be avoided. Hopefully the Beta sells quickly and I get a EC300
