Hi folks,
Thanks in advance for any advice offered.
My father and I have acquired a 1979 Ducati Regolarità 125cc.
Basic description is a two-stroke 125cc enduro motorcycle made between 1975 and 1979. Ducati only made 3500 units, sold (apparently) mostly into Italy and France.
The bike is very complete, but we need a few odds and ends... probably a gasket set for the engine, and a few cosmetic pieces.
Any hints to where I might find parts? I've done a basic search on Ebay and Google with not a lot of luck. Any hidden gems for parts sellers?
Any other important information on the bike you'd like to share?
Thanks,
Mike

When I was working on my '69 450 I ordered some parts from Ducati Vintage in Italy. You might also try Bevel Heaven in CA - I get all my 1975 860GT parts from them, but I don't know if they would have 2 stroke parts.

There is also Guzzino in SoCal.

The lady that runs Ducati Vintage is a lot of fun, but it takes a while for parts to arrive due to customs in NY going in to the US - not sure about Canada.

Good luck, and have fun.

PS - it helps if you speak Italian

Hi Mike,

Well, you know this is likely to prove ... challenging, right :)?! But, FWIW:

Italy has to be your best bet, and that includes looking second-hand. Use Google Italia with search words such as parti ricambio and you get leads like this:

https://www.subito.it/accessori-moto/ricambi-ducati-125-regolarita-alessandria-148039324.htm

Shipping is likely to be difficult and costly. But Good Luck!

Ciao

Craig

P.s The lady at Ducati Vintage is Ombretta Tagliaferri. Very helpful. She used to do sales at Gli Amici dello Scrambler, so I don't know whether she could help with a Regolarità.

P.p.s The other person to try is Ian Gowanloch in Oz. It's not impossible that he has a stash of Regolorità bits in the stuff he picked up in Italy in the '80s. But I haven't heard from/about him for a long while now, so I don't know whether he's still selling stuff.

sgus and Craig,
Thanks for your replies.
I don't know if we've been blessed, or cursed... we now have 2 Regolaritas...
So far, we've been able to repair/rebuild or source everything we've needed, except some cosmetic stuff that will likely be unobtanium.
The one thing we do need is a set of rings for one of the engines.
There's a piston/ring set for sale on fleabay right now, priced at about $600CAD delivered. Yikes, considering that we really only need the rings.
We're wondering if the engine was built by someone other than Ducati... perhaps Sachs?
If it was manufactured by Sachs, then this certainly opens up the availability of spare parts.

I've contacted some sources in North America (nobody has anything) and Gowanloch (no response yet).
My google skills are usually pretty good, but for whatever reason I cannot find "Vintage Ducati" in Italy... do you guys have a website link for them?

Thanks again.
Mike

Not that there's much available to read about the Regolarità/Six Days/etc but, I've never seen any mention of anyone other than Ducati being involved in the design/production of the engines.

Sounds like you're doing well, Mike. Bravo!

1. Ducati Vintage Store here:
Ducati Vintage Store

2. Agree with SP3. The pistons were most probably made specifically for Ducati by AE Borgo of Turin, a company with links with Ducati dating back to the 1950s. AE Borgo no longer exists, but I've had this thought ...

There's an outfit that you often see at Italian bike fairs that may be able to help. They go by the name of "King of Piston" and they even have a web site!

Good Luck and please keep us posted!

Mike, in regards to your needing piston rings. I needed rings for my 750 GT, I got them from Sealed power piston rings..... now sealed power vintage. I believe they can custom make them. Best of luck on your rebuild.

Well folks, we ended up with two Regolaritas; a red one and a blue one.
The red one was in slightly better shape, so we've got it completed already... as shown below.



Most of the damaged parts have been found on various vintage Ducati websites; fortunately a lot of the simple parts are common between a pile of Italian bikes.

This one is for sale, and will pay for the restoration of the second one (the blue one) that we are keeping. While we like the red, the 70s classic blue metal-flake paint is so awesome that we've decided we will keep it.

Regarding the piston rings for the blue bike... I found 54mm Sachs piston rings on fleabay for something like $25. I thought that it was worth a gamble purchasing the rings... and found that the upper "L" shaped ring (don't know what it's actually called) is identical to the original Ducati (AE Borgo) piston ring. The lower (wiper) ring is not a direct swap, but I think finding a 54mm (plain) ring will be relatively easy.

On that note, I contacted Classic Ducati in the UK, and they had a few parts on their website. Barry responded saying he had more parts, so I sent a shopping list... and haven't received a response. I know they just went through some type of ownership change recently... does anybody know how to contact them, or their new website address?

Long story short... another classic Italian back on the road! And thanks for the support.

Mike

Wiseco is another possible source for rings or pistons.

It's great that you got a couple more rare Ducatis back on the road, so to speak.

The Regolarita came from a time when Ducati was being run by appointed Government Managers. They wanted Ducati to cash in on the current off road bike craze in the US and elsewhere, even though Ducati had only built a couple of small 2 strokes 10 or 15 years earlier. They were primarily 4 stroke road bike specialists.

Nobody wanting an Enduro (dual-sport) or off road bike in the '70s thought of Ducati first...:wink2:

I don't think I even heard of Ducati in the 70's.
Kawasaki was letting the good times roll in their ads, and we were meeting the nicest people on a Honda.
Scary dudes rode Harleys. :laugh:

Great stuff, Mike. Congratulations! If you were a bit nearer, I might even been a potential buyer for the red one. But seeing as I need another bike like a hole in the head, so it's probably just as well the Atlantic is in the way ...:laugh:

But well done!

Time for an update...
The blue Regolarita is complete and ready for the road, following a slightly more in depth restoration that originally planned.
The conrod big end bearing and bearing surface were in rough shape, having been exposed to mouse urine; after mice made themselves a home in the airbox and carb inlet. At the time, nobody had a replacement conrod, so a local engine shop found a replacement conrod. All other engine internals were in good shape, so the engine was put back together.
The swingarm shaft was seized into the swingarm. After many days of fighting it, it came loose... showing severe corrosion on the shaft and bushings. I had a new shaft machined, and replaced the bushings.
Rear sprockets are NLA, so I had one machined.
The super-cool 1970's metal flake fiberglass tank was rotten, mostly on the bottom due to fuel being left in it. I rebuilt the fiberglass base/bottom, retaining the exterior metal flake. Once the fiberglass was repaired, I sealed the entire tank with aircraft fuel tank sealer after cleaning with a variety of solvents, degreasers and soaps. I let the tank dry for months before applying the sealer. The sealer was very thin... almost water consistency. I thought this was the best option to soak into the fiberglass fibers exposed because of the fuel. Multiple layers of sealer were applied, building up a thick layer, and sealing the fiberglass. The tank will be drained after every ride... hopefully preserving the tank forever.
Front and rear Marzocchi forks and shocks were rebuilt.
The plastic airbox/battery box was cracked and broken in multiple locations, so it had to be rebuilt using a two part epoxy.
The front fender/mudguard was broken, so I purchased a vintage style replacement that is very close to original.
The rear fender/mudguard was also broken in multiple spots, and finding a replacement was near impossible. I contacted a local autobody shop supplier about repairing plastic, and they supplied me a two part epoxy used for repairing plastic car bumpers. I used the two-part epoxy in conjunction with fiberglass cloth to repair/replace broken pieces. This worked very well, and actually appears stronger than the original fender, which was really important around the mounting points.
Frame repainted, engine polished/blasted/scuffed as required, rims polished, spokes nuts and bolts re-plated with bright zinc and the electrical harness rebuilt.
Lot of little odds and were sourced from Classic Ducati in the UK... thanks to them for their stash of stuff. Coincidentally, they now have a conrod for the bike... a little too late for me. Everything else for the bike came from all over Europe through fleabay or direct purchases.
I've got three things to complete; the chain guard needs a repair (it's with my welder/fabricator now), the original sump guard is long gone (I will fabricate one out of fiberglass next summer) and the spark arrestor is missing from the expansion chamber (a friend and I will fabricate this item over the winter).
So I've got another rare one on the road. Thanks to all of those folks that have helped directly and indirectly (I'm a lurker on the site, so your posts on other bikes/repair techniques/parts sources has likely helped me with mine).

Hi Mike, this is Barry from Classicducati.co.uk. I sincerely apologise that you didn't receive a reply to your email. Unfortunately, I had a period of poor health at that time and some things were missed. I've just found this site and find the discussions very interesting. Its always great to know that the Ducati community is alive and thriving in so many parts of the world. If anyone is still looking for Regolarita or 6 Days parts we still have a varied catalogue of original new old stock parts as well as parts for other Ducati models. Our website is classicducati.co.uk. Best regards, Barry Jones

Thanks for the reply, I'd be interested in hearing how you're getting on with the bike, I have 2 of my own but due to various problems haven't got around to riding either, other than on our driveway.
Barry.
