i know a guy who has a me-0913 motor with a kelly KLS7275h controller.
they are ac
google says this motor is good for 12kw continuous and 30kw burst.
however, the fellow who has it said the motor is low torque and he couldn't get his motorbike to go faster than 85kph (53mph).
whats going on here?
i had a dc motor (k91 4003) that had the same 12kw/30kw and it ran my car no problem.
any advice/information would be helpful, thankyou

Well first things first: Is the motor able to reach enough speed? I mean is it the right KV (rpm per Volt)?
Because if the KV is too low, then the motor can not go up to the revolutions needed for the speed wanted. Independently of its power.

If it was well chosen then there can be many other problems, from battery power to controller programming.
Without further informations it is imposible to start diagnosis of problems.
