The package includes the MX350-style control module and a 4-pin E300 twist-grip throttle so you can swap parts quickly. Read on to see what fits, how the parts work, and practical installation notes.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I know this controller and throttle will fit my Razor scooter or dirt bike?\u003c\/h3\u003e\n\n\u003cp\u003eCompatibility hinges on model and version numbers. This 24V controller and 4-pin twist throttle are built to match specific Razor E200 and E300 scooters and MX350\/MX400 dirt rocket bikes across several version ranges. Always check the printed controller model and the throttle connector before ordering.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eCompatible scooters: Razor E300 Version 20+, E200 Versions 13–23\u003c\/li\u003e\n  \u003cli\u003eCompatible bikes: Razor MX350 Versions 33–36 and MX400 Versions 33–36\u003c\/li\u003e\n  \u003cli\u003eController model reference: ZK2430-D-FS-ROHS (verify on your existing unit)\u003c\/li\u003e\n  \u003cli\u003eThrottle connector: 4-pin male—confirm the connector shape matches your wiring harness\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat does the controller actually do and why replace it?\u003c\/h3\u003e\n\n\u003cp\u003eThe controller translates rider input from the throttle into motor commands that regulate speed, torque and braking behavior. Replacing a faulty controller restores predictable acceleration and can include built-in protections to limit current in fault conditions, reducing the risk of damage to motor or electronics.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eConverts throttle voltage signals into motor speed and torque outputs\u003c\/li\u003e\n  \u003cli\u003eSupports mode switching for different road or load conditions\u003c\/li\u003e\n  \u003cli\u003ePower-off and over-current protection to limit damage during faults\u003c\/li\u003e\n  \u003cli\u003eImproves acceleration response and braking control when defective unit is replaced\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the twist-grip throttle work with the control module?\u003c\/h3\u003e\n\n\u003cp\u003eThe included MX350-style twist throttle senses rotational movement via an internal magnetic or potentiometer element and outputs a corresponding voltage to the controller.
