1. would the 9" motor and motorcycle transmission be a good match for blazing performance?

I'd go with No

48 volts will do that; very slowly, but it will do it.

Automotive transmission
Reduction housing built to go on a tail shaft
Industrial transmission
Direct drive is cheapest.
We can do the math to see what kind of performance is available. Have you tried eve's ev calculator?

What is the target vehicle? I hear 1500 lbs, Motorcycle, passangers so I'm not really sure what we are working with.
