Hardly - IZh motorcycle factory was liquidated years ago. Today in Izhevsk exist C-moto assembly plant. Their production is sold in Russia under brand name Patron.
No. Jupiter’s twin cylinder is based on DKW RT 350 design.
However, there was a period of cooperation between them. Jawa was developing 500 cc boxer engine, and several of these engine took IZh. and tested them on their bikes. Sadly, neither Jawa nor IZh. did not start serial production of that boxer engine.
Do you know what is even more interesting in this story of Jawa’s twostrokers?
This 350 cc before-the-great-flood engine in the late 80’s - early 90’s got a replacement - a modern 250 cc single cylinder liquid-cooled twostroker. The engine was installed into a motorcycle with the same design as the twostrokers that are sold today, plus a fairing and single shock on the swingarm. I do not know what happened, why they decided to keep the old engine, while the new engine lapse into oblivion.

Earlier there were even fewer.
"Ugly utilitarian look" you say?

It was not a rumor. Indeed the Russians bought a license from Yamaha for their thumper, but, as I understand it, the problem was that at that time the Soviet Union was no proper engine oil (???), then the Russians tried to "improve" engine design. And then, there were some other factors why that project was not carried to the end.

You know, Eastern bloc has not been Borg. :lol8:
Each manufacturer has worked for himself with rare exceptions.
ČZ - to be more precise. Note the Č, not C letter. It stands for Česka Zbrojovka, better known as firearms factory. CZ is for Serbia’s firearms/automotive factory Crvena Zastava.
ČZ’s bikes are, in my understanding, mostly off-roaders.
Where is mod, to transfer all this off-topic elsewhere!?
