The CX gets a mention - but check out the Russian V4.

Thanks 4 posting.....some of the "usual suspects" (Guzzis)...some new to me...

On second watching also would love to know why the engineers decided on 66degrees to 90degrees... we know the Cx story.😉

You might say it was to keep the heads out of the way. But the marashuo lilac employed a 80 deg head also.v Having the same engineer might have been the connection?

My mistake, the bergmeister was the 80:degree, the lilac was the 66.

I believe that it is a V-twin, not a V4. See here for a little history. AUTOSOVIET - All about the Eastern cars and motorcycles

OK Mike. I have yet to actually watch it.

I skimmed it without sound before posting it to here and added it to a playlist for that evening.

I was in the shed removing some stubborn screws from some switchgear when it played.

I'll check your link tomorrow. I'm just doing a few jobs before heading to bed.

I watched it a few times to see if i missed the obvious....the head shape is unusual...but 1 spark plug on each side.....

I think that it is a flathead engine with the valves to the rear of the cylinder, under that part of the head which looks like it might be a second cylinder.

The design on that bike is beautiful. Love the seat attached to the curved frame.

Many a Russian design/style has been innovative....
Digressing.. i collect Russian Watches...their "diving watches" feature seals that increase their effectiveness as diving depths increase...despite a somewhat crude design....and at 1/10 the cost of a seiko divers watch ..
(Vostok Amphibian ).....
In the West we have missed out on some of these better examples/innovative designs..
