Hi everyone , this is my other Bike . 82 Gl500 Silverwing base . I just upgraded the old air suspension with an early 2000's CBR600 shock with reservoir . Easy to do ( couple washers for spacers ) . OMG , it rides like a new bike , firmer , and now I can ride two up . Absolutely love it . I highly recccomend if you have a Gl500/600 .
