In ref to the "turn key" statement, it's basically WWII tech.
I've seen similar statements posted like ten times.
The technology isn't that old. They just had an engine redesign less than 10 years ago to help meet American/European emission specs. New Urals have overhead valves, auto-advancing electronic ignition, constant velocity (CV) carbs, electronic starters, reverse gearboxes, 12 volt alternators, rear shocks/swingarms, a front disc brake, catalytic converters, paper air filters, paper oil filters, extended maintenance intervals, etc. It's more like 1980's-1990's tech.
Park a new Ural next to an M-72, K-750, or even a 1980's MT-12 and it's like putting a jet fighter next to a biplane: sidevalves, manual advance points ignition, atmosphere-vented slide carbs with manual chokes, kick-start only, 4-speed gearbox, 6 volt generators (dynamos), sprung rear suspension (M-72 only), drum brakes all around, fuel venting exhaust, oil-bath air filters, oil slinger oil filtration that requires digging into the engine to clean, shorter maintenance intervals (e.g., check the valves every 300-600 miles, de-coke the heads/cylinders every 3000-6000 miles), etc.

You're as bad as Bokad. You're destroying the myth that so many Ural owners cling too. These really are WWII bikes made today. They can be painted in RAL colours and used for re-enaction as "genuine" Nazi war machines. Stop destroying the fantasies of hundreds if not thousands of Ural owners. Why they even have 2WD just like the R75 and KS 750. (Shame it didn't appear until the early 1990's).

Really, If you think about it a Ural is a bit of an enigma.

Roller bearing mains and crank was old school by the 40's, The OHV push rod layout was fairly universal by the 50's, proper oil filtration came into general use by 70's, CV carbs, and catalytic converters the 80's, the electronic ignition is high tech 90's.

Not 40's, not modern, but a little bit of everything. Vintage with some necessary modern additions.

Life is too short to criticize other folks for doing what makes them happy, but I must admit painting up a Ural to look like a WWII German rig is a bit.......................

Don't know much about Japanese engines of the 1960's, 1970's or 1980's do you? Honda 450, Kwaka 9 and GS750 all had roller bearing engines. Still waiting for catalytic converters on some bikes here. Lots of brands consigned CV carbs to the garbage can in favour of EFI and EI.

OHC engines are antique. Dnepr had plain bearing engines three years before BMW. Zündapp thirty years or more. So you're basic point is?

The Soviets only changed things that were absolutely necessary. Think about it, the first overhauls of the basic M-72 design had nothing to do with the engine (technically, there was a 4hp power bump to 26hp on the K-750), it was swingarm suspension all the way around including the sidecar. Then about the same time Ural was developing the OHV engine, Dnepr was designing 2WD and a better gearbox. The original flathead engine was totally adequate and was offered as an option on some Dneprs all the way up to about 1985! And, as IMZ (Ural) logically decided on the OHV engine, you really don't need exotic bearings and oiling systems on an OHV engine that only generated 28hp! (Although they would squeeze about 36hp out of it.) Even today, I think the the new 750 only puts out 38-40hp and doesn't really require anything more exotic than an oil slinging system. In comparison, the Dnepr 650 had about the same power output (36-38hp, with a few escort models getting tweaked up to 52hp) with 100 fewer cc's but a high pressure oiling system.

And as for the OHV design being universal by the 1950's, after the R-71, BMW never made another flathead!!!

Hey Scott,
Don't forget that HD built flatheads until 1973-74.

Oh, I know!
But the big thing that makes the Soviet flattie so amazing in comparison is that it was air-cooled!!!

(But I still really dig the H-D flathead bikes! )

And it's kinda funny when you think about it, the last substantial American and Soviet flathead motorscycle engines actually powered two wheels in a three-wheel configuration: The Servi-Car and the MT-12...

This shit is still going??? People need to either:

A. Get laid
B. Go for a ride
C. Both A & B

Oh and that is post #1000. That is the height of my wisdom to add to this site.
