Mv 175 CSS racing

Hello all!
this is my first post in this forum looking for help. I am living in Germany, an italian friend brought this bike over the alps from a collector in Northern Italy.
It looks like a race modified 175cc "Disco Volante".
It has an aluminium fairing "dustbin" style.
Not sure if it is a possible works modified bike.
Or someone made this conversion for historic racing.
The engine number is hardly legible because the engine was somehow polished. Readable are the numbers ..3450..
The frame number on the headstock reads 405621 (35).
My friend told me there is an old insurance police for 10.000Lire for the bike with three riders mentioned:
Carlo Ubbiali as "official" rider, Roberto Colombo for second category and Remo Venturi for third category,
whatever this means. I haven´t seen the paper in person.

Can anybody help me with informations about the bike?

Here are the pics:

Very nice....

I believe at one time there were classes for many displacements...maybe 175s too??

I used to be fast....now I just dream about it.

Thumbs up

I can't help you the history - but that machine is BEAST - WOW!

I don't believe there was ever a 175 class certainly not in GP - they did have 50 & 80 cc classes, too lazy to research prefer to test my brain and ward off dementia

Congratulations to your friend on a wonderful acquisition

Very nice bike. It gives us a real historic feeling back to the 50ties.

I think it is a private work based on a CS or CSS probably on a Disco Volante. In Italy they did race in the 175 class and I think it was very popular in this time. For me it is not so important if Mr. Ubbiali or someone else raced that bike. It has a real spirit, wonderful. What do you want to do with your little juwel? Ride it!!

Greetings

Alexander

Yes, we want to ride it, but I just started to look after the engine,
cleaned the carb and noticed the slide has a lot of play, no spark so far, maybe the coil, condenser whatever..

What oil would you suggest for this "high-performance" engine?

I guess it is a CS or Disco Volante motor.
It is not a CSS because there is a normal camshaft as far as I can see.

I wonder how it goes around sharp curves because steering is limited through the front fairing brace between the fork tubes,
I guess that was the reason why they banned the dustbin fairings in 1957 or so.

I keep you informed!

Dustbin fairings were banned because they made the motorcycles unstable
