razor mx 500 upgrade

What parts would I need to upgrade my mx 500 to run faster and not sacrifice its hill climbing ability.

That would require a more powerful motor and speed controller. The Razor MX500 dirt bike has a 500 Watt motor so upgrading it to a 750 or 1000 Watt motor would give it a little more speed and better hill climbing. With a larger motor installed then a larger motor sprocket or smaller wheel sprocket could be installed to give it a good amount more speed and the same hill climbing ability.


Our MOT-36750 36 Volt 750 Watt motor will fit into the frame of the MX500, however our MOT-361000 36 Volt 1000 Watt motor is a half an inch longer than the original motor so installing it would require metal work to the bike's frame to make it fit in between the two motor mounting plates.


Please let us know if you have any questions.

Which 36 volt controller do i need for the 750 watt motor.
Our 36 Volt 800 Watt controller, item # SPD-36800B, would be the best controller to use with a 36 Volt 750 Watt motor.


Please let us know if you have any questions.
