10kw 72v bldc motorcycle parts list

[Melontiptron]

I'm trying to put together a kit that will have good power and still practically be able to fit a battery to run a sportbike frame most likely an R1. Perhaps a 100ah 72v lifepo4. I've checked and i think it will fit but it wieghs 126pounds is this too much. I am looking at using a 10kw dc sycronis brushless motor with regen. Is all of this practical. is the motor good? Is the battery enough?
