Chapter 4 Motorcycle Radio Installation
NOTE: This installation is not applicable for 100W radios.
4.1 Motorcycle Radio Description
The motorcycle model includes all the same components in the standard radio, with the exceptions
listed in the model charts in the XTL 5000 Basic Service Manual (Motorola publication part number
6881096C73). The following paragraphs describe the unique items provided with the motorcycle
models.
NOTE: The XTL 5000 Basic Service Manual includes complete parts lists and parts numbers for all
parts shown in the exploded views in this chapter.
4.1.1 Transceiver Enclosure
The transceiver is mounted in the weather-resistant enclosure that consists of a bottom housing and
a hinged top cover. The top cover has a locking latch that requires a key to open. The enclosure is
mounted above the rear motorcycle wheel, oriented so that the lock is forward and the hinged cover
opens toward the rear of the motorcycle. The bottom housing has a grommeted hole for cable entry
and weep holes to permit water drainage.
The enclosure is mounted on the motorcycle with a universal mounting plate and shock and vibration
isolators. A large, braided ground-strap (installed between the mounting plate bolts and the
motorcycle frame) grounds the transceiver.
4.1.2 Control/Display Unit
All radio functions, except push-to-talk (PTT), are activated from the control head, which also is
weather-resistant. The control head and the external speaker are mounted for easy access near the
center of the handlebars. The control head is positioned for unobstructed viewing, and it may be
tilted on the horizontal axis for ease of viewing. The microphone cable port on the front of the control
head is plugged and is not used.
4.1.3 Control Head Cable
The control-head cable connects the control head to the transceiver. This 2.8-meter cable is routed
along the motorcycle’s frame and has weather-resistant connections at both ends. Excess cable is
coiled under the transceiver inside the weather-resistant enclosure.
Each end of the cable is strain-relieved with jackscrews at the control head and the transceiver. The
cable is shielded to reduce the effects of radio frequency interference and ignition noise.
4.1.4 Microphone
A weather-resistant, palm microphone and coiled cord plug into a pigtail connector on the control
cable. The microphone attaches to a hang-up bracket located within easy reach of the motorcycle
rider. The coiled cord is long enough to be operated by someone standing next to the motorcycle, yet
short enough to not interfere with the motorcycle’s steering or operation.
