Kit Warning: Our item # MOT-481000 and MOT-481000B 48 Volt 1000 Watt motors are too long to fit in the MX500, MX650, and SX500 frame and would require metal fabrication and welding to install.
Our item # MOT-48750 48 Volt 750 Watt motor does fit in the MX500, MX650, and SX500 frame and is suitable to use with this kit.
This kit is sometimes used to overvolt the MX500, MX650, and SX500 dirt bike's original 36 Volt motor, however, depending on riding conditions overvolting the original motor may cause it to run hotter than normal and decrease its lifespan.
We install matching connectors on every part of this kit and label them so all you have to do is plug the parts together.
This MX500, MX650 and SX500 modification kit is electronically 100%
plug-and-play, however, it does require custom installation of the
batteries and controller. Custom installation of the batteries may require battery tray modifications because the original battery pack has three batteries and this kit's battery pack has four batteries.
