In 1983 the GL500 was superseded by the GL650 with the new 674cc engine which produced 60hp. The GL650 also had the gear ratios changed to provide taller gearing for highway cruising resulting in improved highway fuel consumption by comparison with its smaller capacity but shorter geared sibling. The GL650 Silver Wing Interstate was only produced for the 1983 model year. Brakes for the GL500 and GL650 were the dual front discs and the fuel tank capacity was 4.6 US gallons (17.5 liters). Dry weight of these bikes was 478 lbs and the fact that these bikes were quite heavy for their capacity did not aid their sales.
