Question on installaion of Bafang g062.1000.DC 1000W

Hello to all

I would like to buy 1000W Bafang g062.1000.DC motor,

this : https://bafang-e.com/en/oem-area/components/component/motor/rm-g0627501000dc/

I see that a 175mm frame is required on the site, my e-bike has a 190mm frame, does anyone know if I can mount it?

What frame? You might be able to cheat a 2mm worth of washers on each side of motor....squeeze frame drops (aluminum frame will only give a little before things break) in to make up the rest? The axle is pretty narrow to begin with, so not much room to play.
You could also put your anti-spin washers (and torque-arms if you are using) on inside frame to get a few more mm.

Using spacers or whatever, at risk would be disk brake alignment (rotor centering in caliper), and your chain line/derailleur alignment.
