Powered, geared, and test proven for speeds up to 26 MPH.
This kit has been upgraded from its original 1600 Watt motor to the new 1800 Watt motor.
This NB (no batteries) series kit is the exact same kit as our KIT-MX481800-3 kit only without the batteries or battery charger. There is the option to add a 48 Volt 1.6 Amp charger for lead-acid batteries to this kit if needed though.
If you already purchased a 48 Volt battery pack to overvolt a Razor MX500, MX650 or SX500 dirt bike and now want even more power and speed then this is the right kit for you.
The switch on the throttle activates the speed limiter function of the controller. When the controller's speed limiter function is switched on the motor will operate at reduced power for slower speeds and a longer ride-time.
The motor in this kit is the same size as the original motor and directly replaces it with only one metal tab spacer needing to be cut off the bike's frame so the motor's power cord does not hit it, and one 1/4" hole drilled into the inside of the frame for one of the motor's bolt heads to fit inside.1/4" Hole Template Directions (PDF)
This modification kit requires custom installation (mounting) of the battery pack and controller.
This kit is electronically 100% plug-and-play. We install matching
connectors on every part of this kit and label them so all you have to
do is plug everything together.
