Our replacement single-speed 4-wire twist grip throttle for Razor MX125 and SX125 dirt bikes uses 28" wires. The length is slightly longer than those on MX125 and SX125 dirt bikes fresh from the Razor factory, but we have found that most people prefer to have a bit extra than too little as they are threading the wires from up on the handlebar to the controller.
Compatible with the Razor MX350 (versions 9 and up), the Razor MX400 (versions 1 and up), and the Razor Pocket Rocket (versions 7 Note: Model versions can be determined based on the product ID code on your Razor product. The product ID code can be found on the battery cover and/or on the bottom of the frame. The 7th and 8th numbers in your product ID code are the version number of your Razor product (e.g. "01" = Version 1, "02" = Version 2, etc.).
