I've picked up an '88 CZ125 (I know) as a bit of a toy. It cost me next to nothing and is worth about the same but im weirdly fascinated by them. I've had to source a new wheel and fork lowers but the rest is solid. I'd like to do an oily rag renovation on it. There is a fair bit of surface rust in other places but nothing at all structural. How do I best go about removing the rust/should I even? I'd normally have the whole thing powdercoated but as above with the value of it and wanting to preserve its history I don't want to go that far. It'll be used for a few charity runs and maybe a bit of touring so needs to be a fairly durable finish.

Hammerite. Clean off the loose rust (or sand down to the metal if you're feeling fancy) and just paint straight over the top.

Lasts surprisingly well and you get that authentic rat-bike look. Perfect for a CZ.

If you want to leave the rust you could coat it in XCP rust blocker clear coat.

If you want to clean it up with minimal disassembly a wire wheel on a dremmel type tool would be handy.

We need pics really

It's amazing how well a dremel and a scouring pad can clean up rust and then just a wipe with an oily rag will keep it at bay

Kurust and smoothrite (not the original hammerite) work pretty well if it's beyond the above fettling

Stripping and powder coating everything is overkill on bikes like these.

CZs and Jawas (and MZs) had poor finish straight out of the factory, with rough castings, lots of badly painted parts and scabby chrome.

These were cheap eastern bloc bikes which allowed our socialist and communist comrades to get from home to the tractor factory and back.

Their crude simplicity is part of their charm and they lend themselves perfectly to oily rag maintenance.

A tin of satin black chassis paint should take care of most of the cosmetics.
