What do you guys think about buying one of they bikes with the new 14K liquid cooled QS motors?

I know its not a Zero but its cheaper. $4100 without battery
The 14K also comes as a kit for $2000.. Anyone ordered one?

I would not want to have >40kg of unsprung rear wheel mass in such powerful Motorcycle
Is there no alternative with mid-drive?
 
I have already 14kW air cooled version in use!
For long distance I would prefer water cooled version.
I run this motor in GSX-R 1000 K2 with KLS14401 because I ordered the 144V version of motor type cause I wanna go first with KHB 14601C but got a lot of problems by parameterisation.
So I changed to KLS and it worked at 100% of motor phase current and battery current without any problems.
But I have another intention, I do not need long distance drive, only quatermile!
I made a test run on airport landing field and reached 200,49 kph (gps measured) @ 175VDC within 20 seconds. 0-100 kph in 7 seconds but this was the effect that I only have 400A phase current!
Now I bought Emsiso emDrive500 controller and hope to get a better result with up to 800A phase current!
This I will see by next year!

Ok. I prefer a mid drive too.. sprung and center weight but in what frame and what motor with 14k+ power?

Everything seems to be going towards mid drives but does someone sell a mid motor motorcycle frame kit like the Enduro is for ebikes/hub?

If you prefer middrive take watercooled DLC-28 motor,
it´s also cheaper than QS. But to fit it you have to think of your own.
Everything depends of the aerea you want to drive.
Only streets: hubmotor is ok
Cross: would prefer middrive
