This Universal Parts 4-Wire Variable Speed Twist Grip Throttle restores smooth speed control to the Razor MX350 Dirt Rocket, versions 1 to 7 (24V). It gives true variable acceleration instead of an on/off response, and its built-in battery level indicator shows your charge at a glance. It's a direct replacement for worn, sticky, or dead factory throttles. Cross-references Razor part W15128040043.
Version tip: To find your Razor version number, locate the ID barcode on your unit (usually on the battery cover or the bottom of the frame). The 7th and 8th digits of the barcode are your version number (for example, "01" = Version 1).
The terminals come loose, without a plug housing. Transfer them into your original connector housing or connect them to your harness, matching the wire colors. Disconnect the battery before you start.
