Motorcycle Radio Installation Installation Overview
All APX mobile radios are tested and inspected before shipment. It is, however, suggested that the
transmitter frequency, deviation, and power output be checked at the time of installation. It is the
license holder's responsibility to ensure that the operating parameters of his station comply with
applicable laws governing radio communications equipment. For tests and alignment procedures,
refer to the appropriate service manual (refer to
Generally, the installation of the motorcycle radio takes place in the following parts:
• Mounting the universal mounting plate and related hardware at the rear of the motorcycle;
• Mounting the control head, speaker, microphone, and related hardware forward on the
• Routing the power cable, control-head cable, speaker cable, and ignition sense cable to the
• Mounting the weather-resistant enclosure and radio chassis, and connecting the cables;
• Mounting the antenna(s) to the weather-resistant enclosure.
A universal mounting plate, supplied by Motorola, is first mounted to either a motorcycle carrier at the
rear of the motorcycle or to the rear frame of the motorcycle itself. The mounting procedures for the
universal mounting plate vary from motorcycle to motorcycle. Therefore, the procedures given in this
manual for installing the mounting plate may not specifically apply, but are provided for guidance.
The control head, speaker, and microphone are mounted forward on the motorcycle, on or near the
steering column. There are several possible mounting configurations which use a combination of
Motorola and customer-built brackets. These configurations are outlined in this manual. Because of
the large number of motorcycle makes and models in existence, the customer-built brackets are
necessary to tailor the mounting of the Motorola equipment to the particular motorcycle being used.
Suggestions for customer-built brackets are given in this manual.
The power cable, control-head cable, speaker cable, and ignition sense cable are routed to the
weather-resistant enclosure position. The enclosure and the radio chassis are then mounted. Special
care is required when connecting cables to the radio equipment within the enclosure.
