This is a modification kit which requires custom installation of motor, speed controller, and battery pack.
The original power switch, charger port, and brake lever are reused with this kit and connect to the controller with the provided adapters.
The chain included with this kit will be oversized so it can be shortened to the correct length after the motor and wheel sprocket are installed.
All connectors and adapters are labeled for easy plug-and-play wiring connections.
When this kit is installed on an MX350 or MX400 dirt bike the top speed on flat ground will be around 20 MPH.
