Sur-Ron has made just a few prototypes so far, but they are in production now and up for sale as soon as the first production run clears the factory.

I've been in touch with a guy named Daniel Orlov who replied back to the email address (6204278@gmail.com) listed on the web site.
The images on the web page are confusing and Daniel has told me they are images of a prototype, not a production motor.
The specs say 6666 RPM and 9000 RPM, but no KV's.
Asking Daniel about this he told me 66.6kv and 100kv and that the RPM's were achieved at 80v.
I can do basic math with the best of them and calculate forwards and backwards to get voltage, Kv and RPM. The math doesn't work out.
I posted this in my last email to Daniel:
These Kv's and the voltage you mentioned in your response don't match up with each other or the information on the web page. I'm not sure what is true at the moment.
66.6kv at 100v = 6,660 RPM max (Very close to 6666 RPM as listed on the web page and mentioned by you.)
100kv at 100v = 10,000 RPM max (Trying to stick with 100v. That doesn't match up to anything.)
100kv x 90v = 9000 RPM max (Not 100v or 80v to get 9000 RPM.)
66.6kv x 80v = 5328 RPM max (80v is what you said the test voltage was. Doesn't match with 6666 RPM.)
100kv x 80v = 8000 RPM max (80v is what you said. Not matching with 9000 RPM.)
Going backwards...
6666 RPM/80v = 83.3 Kv (A lot higher than 66.6kv and lots lower than 100kv.)
9000 RPM/80v = 112.5 Kv (This is pretty high for a 181mm outrunner. Most outrunners of this size are down in the 40-70kv range.)
Again...I'm not sure what information is correct. Nothing checks out or matches up with what you told me or is found on the web page.
Looking at the pictures on the web page, it appears the stator has 27 teeth and the armature 18 magnets. I'm not 100% sure about either of those counts as you can't see the entire stator or armature. I'm guessing based on the typical stuff you see in outrunners. It looks like the larger magnets are about 2X wider than a stator tooth.
Daniel told me the motor is made by a guy or company...not sure which it is...named Roman or YTW200. He even gave me an address in Moscow.
улица Свободы 35 строение 10, вход со стороны фабрициуса на углу с ул. Свободы.
Svobody street 35, building 10, the entrance from the factory on the corner from st. Of freedom.
Google maps satellite view of this address looks like an apartment building to me. LOL
Does anybody know anything about this motor?
Is anybody in Moscow that can go check it out?
This is the images from the web page:
What's going on with the magnets? They protrude in one image and are flush in the other. What's with the smaller magnets? Neo magnets are usually coated in chrome or copper and the actual magnet is a dull silver color. Sumarium Cobalt magnets can be blackish but these really look like ceramic magnets. Maybe the bigger ones are not Neo's? Maybe the little ones are Neo's? I've never sen a magnet spacing like this before with 2 big magnets and 1 little one. Weird!
Motor bell and bottom of the stator.
You can see that the magnet is 2X wider than a stator tooth. I wonder what a "Reaper bike" is. I googled this and found a modded Honda GROM...not it. You can see part of a web site URL "...motors.com" and possibly "Montenegro". TIG or MIG welds to the shaft? A circlip ought to work.
