Plug and play power upgrade kit for version 37 and up MX350 and MX400 dirt bikes.
This kit has a variable-speed twist throttle and controller.
Includes a large heavy-duty double-sided foam mounting tape pad for the controller.
24 Volt 450 Watt motor has the same bolt-hole pattern as the bike's original motor.
Provides around the same top speed as the original motor with improved acceleration and hill climbing ability.
A faster top speed could be achieved with this kit if a smaller wheel sprocket was installed along with it.
We carry a 3 MPH top speed increase wheel sprocket and chain for this kit.
