Top photo looks like Moiseev's 75 mount. Pre MC5 but with the number one plate. Forks would be specials as Moiseev preferred inline forks at this time. Probably 9" 38mm Cherries. Bottom photo is a late 75 (maybe) 125 with what looks like 8" 35mm Cherries but probably have less travel.

Ok, so a bit of a longshot to try to get Moiseev's factory forks then?? ::)

8" travel 35mm is perfect, what models where they on?

They are Ceriani.

They come in lots of different lengths, you can have parallel top tubes or taper tops  (pics shows taper tops)
They have mag or alloy sliders, all manner of brackets for torque arm or non torque arm and the sliders come in various lengths and have eaitehr plain bores or bushes etc etc etc.
They are basically the same, but there are lots of variations on a theme.
Most bikes coming out of Italy in the 70s had them (or Marzocchis)
I have new nuts, seals, dust seal covers, tubes etc etc (got a brand new set if required!)

Why not do it the other way and say what length you want, how much travel is needed and what front brake you'll need and go from there.

The top pic is definitely Moiseevs bike , you can tell by the straight swingarm and advanced pipe design as well as the inline forks . You can get similar forks on  ebay now and then.

OK.
It's for my Cheney Honda Cantilever.

My bike came with Marzocchi 35mm, 9"+ travel, leading-axle forks. It's too tall and looks too modern on the bike, need to make it lower, 75'ish, to look good.

It also came with a nice set of Grimeca wheels, wich I want to keep on. The frontbrake needs a torquearm (with the cablebracket on, like a mid 70's Maico)

So I'd like a fork with the axle in the middle, with a torquearmbracket, 8" travel. I have a set of Betor 35mm trippleclamps with big offset, but it would be best with the fork and yokes the same brand...

And the Ceriani would look good polished with the plated frame...

The build is a bit forward in time, just starting to look for parts. :)

The issue you will have is with the triple clamp offset.
You need to run the appropriate set of clamps for the inline forks. The leading axle fork clamps have a smaller offset.
Hence why the Moiseev's pics has extensions out of the frame for turning stops, when compared to the MC5 frame.

Ahh, sorry, haven't had time to follow up on this, that last ebay set wold have worked great... :-\

Thanks for the tips anyway guys!

And yes, I will also swap the camps to someone with big ofset for inline axle forks, I have a set for Betor 35mm's, but it would be coolest to get a complete Ceriani fork with clamps.

I have a friend in Italy looking for me, but any other tips are also appreciated ;)

VA Montesa have a great set of inline Betor 35ml forks  with about 9inchs of travel.

The forks you're referring to are 210mm travel 35 mm Cerianis. I used a set on my 74 Ktm/ Penton 250 in 99 when I changed it to GP1 Class. Great forks, but hens teeth to find. Moiseev's bike shown is 75 works bike.  Later in year he rode one looking more like an MC5. He did run the straight axle forks until 79. Not sure why, have him as a FB friend..i could ask if i could translate well

I think the ones your friend got for you Martin are the magnesium leg version going by the gussets on the leg. I've got 35mm Cerianis with YSS PD valves in my Cheney and they're pretty bloody good. I'm intending on using an identical set to the ones photographed above on my Hindall RT2MX but I'm using Betor or CZ internals with PD valves because the Ceriani originals are rusted up. Shaun Giles has a similar Cheney XL to yours and it came with Cheney's own forks but his dad replaced them with 9" travel AW Maico forks back in the day and the originals have disappeared. I'm not 100% certain but I think Shaun's retrofitting Betors to his.
