The E-Kit consists of 1 throttle assembly (4-wire / no lights /single speed) and 1 control module (model # HB2430DYC-FS).
Not compatible with MX350/MX400 Bikes Versions 33 and up.
IMPORTANT NOTE: Razor product versions can be determined by locating your bar code ID on the bottom of the bottom of the product frame or on the battery cover. The 7th and 8th digit in the series will tell you the version of your product: 01=version 1; 02=version 2; 09=version 9, and so on. You need to know your version number in order for this conversion kit to be compatible, as this module/throttle combo is only compatible with certain versions of Razor MX350 and MX400.
