Rob a couple of words of warning here, as i've been down this route.

Marzocchi internals won't fit inside the lower section of the ceriani stanchions, so if you use Marzocchi sliders and ceriani stanchions you'll need the ceriani damper rod and valves.

This was an interesting find, although they are both 38mm stanchions the Ceriani's have a smaller ID, which means there walls are thicker, which could give credence to the view that Ceriani's are better than marzo's eg. stiffer with less flex.

Road & Race stanchions are for a Ducati and have been sitting around for a long, long time. 1st issue, they will have some surface rust you will need to deal with on the inside of the stanchions, nothing a bit of rust inhibitor, wet and dry and elbow grease won't get rid of. 2nd issue, they are for a Ducati so if you have Laverda ceriani caps they won't fit as the thread pitch is different (finer on the Ducati version).

I found all this out the hard way when I purchased the Ceriani stanchions from road and race to retrofit back into a marzo front end. Ended up sourcing a couple of full ceriani front ends instead.

Still have a couple of brand new Laverda Ceriani caps I can't use  >:(

Hi Crispen, the Cerianis are complete with springs and internals so no worries there. R&R have them in 610mm lengths, 20mm short but I have my Marzos thru the yoke 20mm. So I might need to buy fork caps for them as well. What I'd like to know is, can I install my Racetech springs/ emulaters from the Marzo into the Cerianis. If so I'm tempted to go the Ceriani route. Kind of like the Idea of a thicker wall staunchion.
 
Crispin,

Thanks for the heads up - I guess I need some Ducati fork caps then  ::)

Cheers

Hey Grant

Your new lock stops look positively RGS?ish.... what next?  Rubber mounts, a 120 crank and a shed load of bayflex?

I pulled the old Cerianis apart as well as the old marzos I have. It seems the Cerianis valve set-up is gar superior to the Marzos. It's been quite some time since pulling the dampening apart on my Marzos fitted to the 1200 so can't remember whats in it but if my spare set is anything to go by, the Marzos are lacking in parts. The forks have been sitting around for 25 years and can't remember where they came from so maybe some parts are missing. I'll need to pull the 1200 marzos apart to compare.
I'm still keen on using the Ceranis but would like to know if the Racetech springs/goldvalves are transferable to the Cerianis, if so I'll go down that route.
The photo shows the difference between the two dampening set-ups.

Rob,
can't give any definitive answer but I would suspect it all comes down to diameters and lengths.
OD/ID of Marzo vs Ceriani parts and OD of emulators.
Overall length of rods/springs and emulators.
In the Marzos you have a tube at the top that I suppose is tuneable for length easily enough and I don't recall any such thing in Cerianis.

Will the emulators fit into the Ceriani forks and what overall length does it give?

I am still not really familiar with emulators so I may indeed be talking out a hole in my head.
 
The Race tech springs are quite short using preload spacers of around 100mm, can't remember to exact length but I was supprise how short they were when I got them. So installing them into the Cerianis should only mean changing the length of the preload spacers. The Gold Valves are a unit that just drops into the staunchions sitting on top of the damper rod and under the spring. It has a adjuster thats a cap screw to which you can set to what ever your riding style is. 1 turn to 4 turns If I remember correctly. The mods required when fitting to the marzos was to drill another hole in the dampening rod and removing the ball located at the top of the damp rod. I'm thinking it should just drop straight in and then reset the preload with the spacer. I'll call the supplier [Shock Treatment] next week and run it pass them.
The Marzos are certainly simpler down at the business end compared to the Cerianis. I kind of think that there might be some parts missing out of the old marzos though.
 
I picked up some RaceTech emulators for Ceriani 78 Jota. They're 31 mm OD, incidentally. They require a spacer for a bit of clearance when sitting on top of the damper valve, and some extra holes drilled into the damper valve (a bit like the holes drilled into the rod on the Marzocchis). Then you do have to adjust the length of the springs, they have to heated and ground flat at the end when they're cut to length. I should have got RaceTech springs too, my original springs have sagged too much, but aside from that the installation looks pretty easy.
I even got some clipons to use (GSX-R, $5/pair on eBay plus a bit for having spacers made) while I'm dialling in the spring rates, taking the Laverda bars off every time I want to take the fork caps off to adjust the valves didn't excite me at all.

Rob, there is nothing wrong with you picture of the Marz internals - it is all there. Simple, simple, simple.

I fitted YSS emulators last year. Not got them sorted yet though, as I fitted new RT springs at the same time and they are too stiff (0.9kg/mm). Need to swap the springs out to dial in the damping.

Rob,

There's another supplier in Queensland who imports Tarozzi and they're a bit cheaper than Gowies. Probably the supplier for Gowanloch's, the shop not Ian. I gather he, Ian, imports his own from talking to him.

Paul's his name but I'm not sure he can guarantee supply. I've heard he has a bit of bad debt and has wound things back a bit. Worth a call though (after 3pm). He has lots of useful stuff and he's a good bloke who just loves bikes.

Hi Chris,
Checked out that web site, Didn't know Tarozzi supply replacement parts. Going by his prices, roughly $300 each makes them more expensive than Gowies, about $235 each.
Still kind of like the idea of $200 for a pair of Cerianis from Road and Race.

Paul, well compaired to the Cerianis they're real simple then if all the parts are complete.
I'll make some enquiries with Shock Treatment about using the Gold Valves and spings with the Cerianis.

I have Tarozzi Fork tubes and possibly some of their pt numbers as I got some drawings sent through. Only comment I will make is they were slighly large on the OD and it took a lot of fettling of the fork sliders to get them to move (like a couple of days hard graft) ! They wouldn't even go in thats how tight.
Might be worth having your sliders with you, when you go to pick up the tubes incase they dont fit !

Cheers Rob
 
Rob and Rob,

Didn't notice (the fine print) that they were priced each. Doh!! 

That's good to know about the bad fit. Ian Gowanloch told me he gets his from some supplier in Italy. Which I'm assuming isn't Tarozzi. He quoted me a price of $700 for a new set of 630mm fresh out of Italy. I was thinking of putting new ones on mine as well after hearing about the Sydney snapping episode.
I've got a pair of Tarozzi rearsets on my Morini and I have to admit they took a lot of rooting around to fit. There's certainly better quality available elsewhere.

Rob,

is use the Racetech springs and Emulators in the Ceriani's on the Spaceframe. Racetech numbers I am using are:

Springs : FRSP S3234
Emaulators: FEGV S3801

picture shows the guts of the Ceriani with the emulator sitting on spacer, which needs to sit snugly on the top of the damper rod. I think racetech actually sells a spacer if you look up under Ducati 860GT on the racetech site you'll get the spring and emaulator adapter details, or make your own up like I did if you have access to a lathe.

Cheers Crispin

PS the right fork caps will cost you a bomb, probably take up the difference between the Marzo stanchions, but I reckon the Ceriani is the way to go. I sourced a whole new Ceriani front end to get the caps ... yeh I know bit excessive but I got them for a good price and just couldn't stomache what Bevel Heaven wanted for the caps, all after I had already forked out for a set from Andy that didn't fit  :-\

Yes but I suspect they are for Laverda stanchions and will have a different thread pitch, worth checking with him though as he was offering some seconds very reasonably. The pitch on the Ducati caps are finer than the Lav but not sure exactly what it is.
 
Hi Crispen, thanks for that info. I'll have a look back through my records, maybe I'll find the receipt when buying the RT stuff with all the numbers. Numbers aren't on the valve themselves are they?
Maybe R&R sell fork caps. What length staunchions did you buy for the space frame? Think the longest they had were 610mm which would be fine for the Motodd. currently 630mm with 20mm throught the top yoke.
Cheers

Rob,

I went with the shorter ones (580mm I think), the spaceframe is much smaller than you imagine. R&R doesn't have the caps.
 
Crispin

Didn't you have to drill some extra holes in the tops of the damper valves too? I was given a hand-drawn diagram (which seems to have disappeared) of how to install my emulators, which did indicate I had to drill a bunch of holes, and I was waiting until I'd found some extra damper valves so if messed up I wouldn't destroy my ride.
