The SX125 runs on a 12 volt 5 Ah battery and charges through a coaxial port. Most parts are shared with the Razor MX125, and one control module also fits the Pocket Mod Petite. Control modules are listed by version, including one for V6+, so check the version number on the label on the frame and compare it with the part listing. Tires have E351 knobby tread and take an inner tube with a straight valve stem. As an authorized Razor dealer, we supply genuine OEM Razor parts, with compatible alternatives on select items.
