I 500cc 50hp electric motor swap

  1. Jun 12, 2017 #1
    Hi, I own a 1993 ex500 with that is having engine problems, I would like to swap the motor for one that is has more or equal power. The best specs I can come up with are these the motor puts on the rear wheel, HP 50, Torque 31 ft-lbs, top speed 130mph, I am looking into getting a DC-liquid cooled motor.

    What is your requirement for range? 50 HP will drain an extra large car battery in just about one minute. But if your goal is to drag race for 1/4 mile, that's no problem.

    What other electric motorcycles have you seen? How many HP? How big are the batteries?

    I am looking it
    Well maybe I could get away with a 15 or 20kw motor I'd be happy if it went 90 tops. I plan for a 100 mile range. Something like this http://www.thunderstruck-ev.com/motenergy-1302-water-cooled-brushless.html
