'78 CR250 Honda but they were shite.. I think the '86 CR250/500 was the next model to have cartridge forks that actually worked.

Will stand corrected, but I thought that only the 86 CR250 got them - the 125 and 500 had to wait until 87 (I know this is correct for the 125, not 100% on the 500).

I'm gonna have to correct you..
Just checked in the August '86 Motocross Action and the '86 CR500 had cartridge forks.

In my factory manual for my 1984 CR 250 they recommend 534cc per leg of ATF .

I dont know how different 83 to 84 though .

Have you guys got Honda parts books? That would be helpful to you.

Hoony MXA says the '86 US CR500 has cartridge forks, the Aus model may be different but i wouldn't have thought so.

If the Aussie CR500RGs had non-cartridge forks, then it would explain why I thought this since 1987...

The US-based online parts manuals show the 500RGs having cartridge forks, and the 125RGs havng non-cartridge.

We didn't get poverty model CR's in Australia, we got the same as the US except for jetting and spring rates.
