I opened up an engine to strip for a rebuild and noticed the clutch was something I've not seen before. It is a 6-spring basket like on non-200 Vespa engines, but it uses 7-spring clutch corks.

that looks like the old clutch that came out my engine. sent it off to Gene at Scooters O for a rebuild. he said it was from a GS 160, and SS 180. now I have a P200 clutch except for the Rally 180 gear.

If it is a GS clutch that would explain why I'm unfamiliar. There are a few models of Vespa I don't work on and that is one of them.

The GS/SS have a taper on the clutch side, so that can't be it (assuming this is not a GS/SS). But I think the bell may have been the same between the SS and Rally 180. So my guess would be that this is a Rally 180 clutch, but I've only been into a few and that was a long time ago.

Patrick, yes this is a Rally 180. The last couple I've worked on had traditional P200 clutches.

The clutch on my Rally 180 had the same clutch.

that's a GS/SS basket probably fitted on a standard non tapered baseplate...

This was a filthy fucker alright. I cleaned it all yesterday and put new seals in it. I'll get back to finishing on Sunday after seeing the Book of Mormon musical.

I thought it was a GS or SS clutch at first but now I'm happy that I sat back and watched.

Just curious about a couple of things. How else is it similar to the GS/SS? Do you need a clutch puller tool to get it off? Does it have a brass bushing or 40 roller bearings?

It is a typical clutch other than its outward appearance.

it's an early - to - mid rally 180 clutch. uses larger diameter springs. nothing unusual, except the fact that most haven't seen one as it's not as common a model.

it's documented in the parts books. most parts are available, but if you don't want to run down the parts specific to that style (basket, springs, cups and backplate) 7-spring ones can be swapped. the cups, basket and springs are in common with the SS180, but the GS160 style is different as it is a six spring using the standard smaller springs and it is the larger diameter outer diameter and not the smaller diameter six spring commonly seen on 125/150's until 1985.

if you plan to swap in a later style assembly, the standard setup is more like a 150 primary gearing wise, with 22 teeth, although you can up gear to a 200 23/65 combo, it'll pull it. especially if you overbore or swap to a 66.5 200cc setup.
