AlveyTech 24 Volt ZK2430-D-FS-ROHS Controller for The Razor MX350 Dirt Rocket Bike (Versions 33-36) - Replacement Motor Speed Control Module with 4-Wire Throttle Connector

Old computer got water on it stopped it from running. This part fixed it. The wires wasn't long enough to reach the on/off switch so I had to mount the switch on the side. Runs great now

Delivery was delayed multiple days, but the part fit and works good. No complaints on the product itself. Just Amazon delays.

My son was happy it worked on his razor

I was able to replace a new one and the old controller from the manufacture controller got corroded.

First off, there was no packaging. Then, it didn't work. I bought someone's trash. Unbelievable.

This part did the job! Fast delivery

Fits razor exactly as stated and it is heavy duty so it doesn't seem to get as hot as original very pleased will purchase will buy again if neew

2 MAIN Issues with the controller ( MX 350/ MX 400 ): 1. The wiring is too short, you’ll have to ziptie the controller on the Body frame of the bike smh. It still works, but needs more cable management because of the short wires. 2. No Black wire for the Switch light, only the 2 red wires are available. So the switch light won’t light up. Fair warning, overall it works, but those 2 take aways are a red flag.
