Other SUBURBAN 1985 Motorcycles

I am selling my 1985 Voyager 1300.  I purchased it new in 1987 from a local dealer. She came complete with matching helmets and the ground control headsets, which still work for intercom and listening to the radio and cds. I did not opt for the CB radio option. The trip computer has not worked in years.  When the battery starts to go low, the computer actually comes on.  It probably needs some kind of voltage regulator to make it work.
